江苏省海岸带可持续发展初探

在海洋经济区中,海岸带具有一定的特殊性。虽然其资源丰富且种类繁多,但由于受到多种作用力的交互影响,而客观上存在各种灾害频繁、生态环境脆弱等问题,因此迫切需要实施可持续发展。江苏是海洋资源大省,海涂面积占全国海涂总面积高达30%左右,大陆海岸线长度约占全国大陆海岸线总长度的5.3%,但却又是海洋经济弱省,其海洋产业产值仅占全国海洋产业总产值的4.4%,与广东(21.71%)、山东(14.14%)、浙江(14.05%)、福建(12.68%)相比存在很大差距,已经成为江苏区域发展中必须正视和急于解决的突出问题。本文从可持续发展原理出发,通过分析江苏省海岸带的特点及其开发利用现状与存在问题,提出了实施其可持续发展的战略选择以及所应采取的主要措施。     

明清时期广东海防“分路”问题探讨

明清时期,广东的海防部署依据不同的区域划分呈现出循序渐进的"分路"特征,即从元末三路分防的萌芽,到明中叶的全面成型,再到清代四路甚至五路的发展。关于广东海防分路的时间,本文认为早在元末已经出现,当时中路的虎头门、南头澳等地均是重要的海防要塞,明初的广东海防从无备到有备,实际上借鉴了元末的海防实践,而对于肇庆府在明清两代并不归属中路海防区域,本文也明确提出自己的看法。从元末到清末,广东海防分路的漫长发展演变不仅是海防部署工作的细化,更体现了明清两代区域海防工作责任的日益繁重。     

我国沿海港口港城关系协同发展与驱动机制研究

近年来,随着我国港口资源整合、港区功能调整和港口城市的转型升级,沿海港口与所在城市的关系发展面临新的变化和挑战。本文以我国沿海港口为例,结合定量分析与定性讨论,聚焦我国沿海港口港城关系问题,剖析港城关系的演变及驱动机制。研究发现：我国大部分沿海港口已进入极度协调发展阶段,但发展趋势逐渐放缓,区域分化特征显著,港城协同度差距呈现再扩大的发展趋势。在研究期间,我国城市驱动型港口城市数量显著增加,港口驱动型和港城互驱型港口城市数量减少。建议通过政府政策引导、港产城融合发展和港口转型升级等方式,不断提升我国沿海地区港城关系整体协调发展水平,为新时期我国沿海港口与所在城市的高质量发展提供重要支撑。     

Selling surf and turf: throwntogetherness and real estate advertising on the suburbanising east Australian coastline

New residential development is transforming coastal places in Australia. This paper untangles perceptions of coastal change by analysing representations of nature and lifestyles in marketing new residential developments on the New South Wales (NSW) coastline. We focus specifically on master-planned estates (MPEs). In this context MPEs are primarily a consequence of housing affordability and supply dilemmas in capital cities. Their form and character is derided as ‘suburbanisation by the sea’: vandalism of ‘authentic’ coastal cultures. We draw on Massey’s theorisation of place as ‘event’ and a relational politics termed ‘throwntogetherness’ to understand the role of real estate advertising in blending coastal places and MPEs. Our insights are drawn from visits to 19 MPEs for sale on the NSW coast, and discourse analysis of 76 advertisements collected in situ (billboards, signs, banners and brochures). Advertising narratives for new MPEs both sustain and contradict the idea of coastal suburbanisation: portraying permanent settlement by young families as a culture shift and implicating ‘sea change’ configurations of coastal places to do so. This makes lifestyle expectations with coastal nature perplexing. In the throwntogetherness of contemporary coastlines, marked by landscape change and development pressures, real estate advertisements are pivotal in establishing, grounding and guiding change.     

空间思想演变视角下的西方滨海旅游研究

以往滨海旅游研究综述大多限于对所涉研究领域的横向分类,缺乏基于特定学科演进视角下的纵向考察。本文从人文地理学空间思想演变视角出发,重新审视和梳理西方滨海旅游研究的脉络。与空间思想流变过程对应的是,西方滨海旅游研究主题也经历了从"滨海旅游地空间模型与演化"到"滨海旅游空间文化解读与社会建构"再到"滨海旅游空间政治与权力景观"的过程,亦即从关注滨海旅游空间的物质性转变到社会性和政治性。借助人文地理学空间思想演变视角,可以厘清滨海旅游研究视角转换的内在逻辑,并能从空间的生产视角重新思考中国滨海旅游的新一轮发展热潮,为国内滨海旅游研究提供新的思路和方向。     

Perceptions of Risk among Households in Two Australian Coastal Communities

There is limited knowledge of risk perceptions in coastal communities despite their vulnerability to a range of risks including the impacts of climate change. A survey of 400 households in two Australian coastal communities, combined with semi‐structured interviews, provides insight into household perceptions of the relative importance of climatic and non‐climatic risks and the subsequent risk priorities that may inform household adaptive action. In contrast to previous research, the results demonstrated that geographic location and household characteristics might not affect perceptions of vulnerability to environmental hazards. However, past experience was a significant influence, raising the priority of environmental concerns. Overall, the results highlight the priority concerns of coastal households (from finance, to health and environment) and suggest to increase the profile of climate issues in coastal communities climate change strategies need to better demonstrate links between climate vulnerability and other household concerns. Furthermore, promoting generic capacities in isolation from understanding the context in which households construe climate risks is unlikely to yield the changes required to decrease the vulnerability of coastal communities.     

Coastal and marine studies in the department of geography and environment at the University of Aberdeen

ABSTRACT

The Department of Geography and Environment at the University of Aberdeen has a long history of coastal and marine teaching and research from the 1960s to the present day. Beginning with the work of Walton and latterly Ritchie, the paper traces the coastal and marine studies in the Geography degree programme, the development of the Marine and Coastal Resource Management degree, and the introduction of more recent courses such as Managing Our Coasts and Seas, Hydrography, and Land and Marine Conservation. Establishment of the Centre for Marine and Coastal Zone Management (CMCZM), and later the Aberdeen Institute for Coastal Science and Management (AICSM), provided a clear focus for continuing academic research into integrated coastal management and marine spatial planning. This complemented long-term involvement with Shell, SOTEAG (Shetland Oil Terminal Environmental Advisory Group), the Association for Geographic Information (AGI), OceanLab, the EUCC, and several Scottish coastal fora. The creation of the Unmanned Airborne Vehicle (UAV)/Unmanned Airborne System (UAS) Centre for Environmental Monitoring and Mapping (UCEMM) in 2014 brought together the role of remote sensing, GIS and photogrammetry in monitoring, mapping and modelling the coastal environment.     

SHEEPSHEAD COUNTRY: COASTAL WOODLAND SUBSISTENCE FROM THE PERSPECTIVE OF MACK BAYOU AND OTHER NORTHWEST FLORIDA SITES

Abstract

Zooarchaeological analysis of faunal remains from the Mack Bayou site produced new data related to coastal Woodland subsistence on the northern Gulf Coast of Florida. When the Mack Bayou data are compared with data from other Woodland sites on the northern Gulf Coast, a strong pattern of estuarine and shallow coastal waters utilization is evident, with notable but fairly minor site by site variation. It is also evident from these data that sheepshead (Archosargus probatocephalus) are a consistently important dietary component across the northern Gulf Coast, particularly on coastal sites in the Panhandle region of northwestern Florida.     

清初迁海前后的沿海盐场与地方宗族——以广东归德、靖康诸盐场为例

清初迁海给沿海尤其是盐场地区的社会经济带来严重的破坏,但具体影响的范围、程度和方式,却不能仅就官方文献和展界后的赋役情况轻下定论。通过广东归德等盐场及相关宗族在迁海前后的活动情况,我们发现,迁海并没有给盐场宗族主要成员造成太大的影响,相反,官方文献"盐课缺征"、"丁绝田荒"的记载,实际上是盐场家族有意识地利用迁界机遇和制度漏洞,逃避灶课、隐匿盐田,借恢复祖先祭祀之机抢占民田的结果。     

Associations between coastal proximity and children’s mental health in Australia

Limited research has explored associations between blue spaces and mental health, specifically in children. This study assessed links between coastal proximity and depression and anxiety among children in Australia and tested whether duration of residency at current address moderated associations. It also explored associations between within-individual changes in coastal proximity and changes in depression and anxiety. Data were from 2400 children aged 11–12 years in Wave 5 (2012) and aged 14–15 years in Wave 6 (2014) of the national Longitudinal Study of Australian Children. Outcomes were children’s self-reported symptoms of depression and anxiety. Exposure was coastal proximity (<2, 2–<5, 5–<10, 10–<20, 20–<50, and ≥50 km). Linear models were fitted to examine cross-sectional associations and fixed effects models for within-individual associations. After adjustment for potential confounders, findings suggested that those living close to the coast (<2 km) had lower levels of depression than those living the furthest from the coast (≥50 km) during childhood (Wave 5) but not adolescence (Wave 6). No associations were observed with anxiety. There was weak evidence to suggest residency duration moderated associations. No associations were observed for within-individual changes. Further research is needed to understand whether and what characteristics of coastal environments may benefit children’s mental health.

Midden or Molehill: The Role of Coastal Adaptations in Human Evolution and Dispersal

Coastal adaptations have become an important topic in discussions about the evolution and dispersal of Homo sapiens. However, the actual distribution and potential relevance of coastal adaptations (broadly, the use of coastal resources and settlement along shorelines) in these processes remains debated, as is the claim that Neanderthals exhibited similar behaviors. To assess both questions, we performed a systematic review comparing coastal adaptations of H. sapiens during the African Middle Stone Age (MSA) with those of contemporaneous Neanderthals during the European Middle Paleolithic. In both species, systematic use of marine resources and coastal landscapes constitutes a consistent behavioral signature over?~?100,000 years (MIS 6–3) in several regions of Africa and Europe. We found more similarities than differences between Neanderthals and modern humans, with remaining disparities all in degree rather than kind. H. sapiens exploited a wider range of marine resources—particularly shellfish—more intensively. MSA shellfish-bearing sites are also more often associated with intense occupations on coastal landscapes, and more evidence of complex material culture such as shell beads. In terms of broader ramifications, Pleistocene coastal adaptations are best conceived of as an ‘add-on’ to previous adaptive strategies, complementing more frequently exploited inland resources and landscapes. Still, Neanderthals and modern humans increased their dietary breadth and quality, and added options for occupation and range expansion along coastlines. Potential evolutionary implications of these multi-generational behaviors include higher intakes of brain-selective nutrients as a basis for neurobiological changes connected to increased cognitive capacities, but also greater reproductive success, dispersal abilities and behavioral flexibility. Whether gradual differences between modern humans and Neanderthals stimulated different evolutionary trajectories is a question for future research.

     

Assessment of the Programme of Measures for Coastal Lagoon Environmental Restoration Using Cost–Benefit Analysis

The degradation of marine and coastal ecosystems has given rise to the creation of specific protection rules. The Marine Strategy Framework Directive and the Water Framework Directive are the standards agreed in the European Union with the aim of obtaining a good ecological status in marine and coastal waters by applying a programme of measures, if necessary. These measures must be technical, social and economically feasible, in such a way that costs do not exceed benefits. This work expounds the implementation of two economic tools to assess the programme of measures intended for the environmental restoration of one of the most important coastal ecosystems in Europe, the Mar Menor coastal lagoon (SE Spain). Thus, the cost–benefit analysis (CBA) (and its extensions) and the contingent valuation method are used to assess the aforementioned programme in terms of economic and environmental profitability. Results prove the socioeconomic and environmental profitability of the actions due to be undertaken, with rates of return of around 10%. From a methodological point of view, there is a clear need to widen the classic CBA scheme by using the extended CBA and the dual CBA to gauge this type of environmental restoration actions.     

Shoreline Change and Coastal Vulnerability Characterization with Landsat Imagery: A Case Study in the Outer Hebrides,Scotland

Abstract

Observation of cause–effect patterns of change in coastal environments provides insights into vulnerable areas and supports prediction and adaptation to flooding and erosion. Historic and periodic (6–8 year intervals) imagery from the Landsat archive is used to investigate transformations in the Atlantic coast of two Scottish islands over the period 1989–2011. Supervised classification of spectrally normalized images followed by change detection and spatial analysis reveals the patterns of change and the location of the most dynamic coastal areas. Quantitative measures of recent shifts and movement rates of relevant coastal lines, such as the lower limit of land-based vegetation, are assessed with the Digital Shoreline Analysis System. While very low rates are indicated for horizontal changes in the position of the lower limit of land-based vegetation (0.3?m?y^?1), specific areas have been subjected to high rates of coastal progradation as well as erosion (e.g. 2.5?m?y^?1 at Stilligarry). Information derived from satellite data supports the characterization of geomorphologically dynamic coasts at regional scales. With a rich and open access archive of imagery, a commitment to continuity, and compatibility with the Earth observation missions of other space programs, the Landsat mission offers useful and otherwise unavailable data for monitoring of coastal areas.     

Rare animals at a Mississippian chiefly compound: the Irene Mound site (9CH1), Georgia,USA

ABSTRACT

The Irene Mound site (9CH1) was a Middle and Late Mississippian site (ca. AD 1150–1450) situated on a bluff overlooking the lower Savannah River, Georgia (USA), a few kilometers upstream from the Atlantic Ocean. The 2.4 ha site consisted of a sequence of superimposed layers referred to as temple mounds, as well as a burial mound, a rotunda, a few residences, and other structures. It is interpreted as the residence of a chiefly lineage. The presence of animals rare or absent in other precolonial coastal assemblages distinguishes the Irene assemblage from others along the coast. Some of the animals exhibit atypical, even dangerous, behavior, others have elaborate feathers or fine fur, and many are notable coastal fishers. White-tailed deer (Odocoileus virginianus) specimens in the assemblage are dominated by portions from the body. Irene may provide a zooarchaeological standard for assessing evidence of site functions and status in other coastal assemblages.     

Luminescence geochronology and paleoenvironmental implications of coastal deposits of southeast Cyprus

Quaternary stratigraphy and sea level changes have been extensively investigated in many areas of the Mediterranean. However, numerical dating of coastal deposits and the associated paleoenvironmental information are limited for the coasts of Cyprus, principally based on radiometric and radiation-exposure geochronological techniques on fossils which bear a range of limitations and uncertainties. As such, optically stimulated luminescence (OSL) dating techniques are deemed to be the most suitable in direct dating of the coastal sediments of Cyprus. In the southeastern Cyprus, coastal dunes (aeolianites) now forming elongated ridges appear as morphological features running parallel to the current shoreline presenting an indicator of sea level and climate changes of great paleoenvironmental significance. We present our first chronological results for the exposed aeolianites and underlying littoral deposits formed along the southeastern coastal Cyprus ranging from 78.4 ± 9.9 to 56.2 ± 7.4 ka. The post-infrared–infrared stimulated luminescence (pIR-IRSL) revealed that dune formation took place during the marine isotope stages (MISs) 3, 4, and possibly 5a. Late Holocene reworking is proposed for a distinctively isolated dune with an age of ~1.3 ka ago. This study also showed that pIR-IRSL dating of feldspars may be a reliable alternative to quartz OSL dating when the quartz luminescence characteristics are unsuitable.     

基于景观生态的亚热带沿海景观及旅游保护性开发探讨——以福建省为例

沿海景观作为海洋景观与陆地景观的边界,是特色鲜明和空间异质性突出的系统整体。同时沿海地区一直是人类开发较早、人地关系紧密、系统物能交换最频繁、最集中的区域,对海-陆-气系统耦合力和内外营力具有高度的敏感性,因此保持沿海景观的生态整体性尤为重要。研究沿海景观的景观体系和开发利用,目前在我国仍属于薄弱环节。本文评述福建沿海景观分类并概括其生态特征,应用景观生态的原理,探讨福建沿海景观旅游保护性开发模式,构建和谐稳定的景观格局。     

Geoarchaeology of Beirut's ancient harbour,Phoenicia

This paper presents geoarchaeological results from the ancient harbour of Beirut (Lebanon). As at Sidon, knowledge of Beirut's ancient tell has advanced significantly over the past decade, thanks namely to redevelopment of the city centre and excavations centred on the modern port. In spite of this research, understanding of the city's coastal palaeoenvironments during antiquity is poor. Buried Iron Age harbourworks presently 300 m from the sea attest to pronounced coastal changes during the past 3000 years. These processes have been significantly accentuated during the last two centuries by redevelopment of the port, which remains in use some 5000 years after its foundation. Here we elucidate the coastal stratigraphy east and west of the Bronze Age tell to yield new insights into the evolution of the Beirut seaboard, in addition to the complex history of human–environment interactions. These chronostratigraphic data are subsequently used to (1) precisely locate the main anchorage haven during antiquity; and (2) propose a chronology for its evolution.     

Finding a middle ground: Conservation challenges among stakeholders in coastal Tanzania (Respond to this article at http://www.therai.org.uk/at/debate)

Recently, evictions associated with climate change mitigation in the Rufiji Delta of Tanzania sparked intense debate about the ethics of coastal conservation between academics, NGOs (non‐governmental organizations) and government officials working in the region. Some actors argue that environmental change is a myth used to wrest control of natural resources from local communities, while others point to the urgency of environmental protection and action on climate change. Insights gleaned from interviews with multiple government officials, NGO employees, academics, and coastal village residents in Pangani, however, reveal a more complex and perhaps less contentious situation in coastal Tanzania. Although they often proffered different solutions, different stakeholder groups articulated the same key challenges in nuanced ways that shed a more hopeful light on currently heated conservation and development issues.
