Logistic增长模型在游客流量预测中的应用——以贵州省绥阳县为例

旅游开发要以市场为导向,以资源为基础,以产品为核心,以效益为目标。游客流量的准确预测对旅游资源的开发具有很重要的指导作用。现在游客流量预测已经有了一个比较成熟的方法系统,但这些方法大多针对于开发得比较成熟且具有一定的游客数据积累的景区。本文以贵州绥阳县双河溶洞国家地质公园为例,尝试将种群增长的Logistic曲线与景区的环境容量相结合的方法,来预测其未来一定时段的游客流量,得到了较为满意的结果,对国内其它类似旅游景区开发具有借鉴意义。

非市场竞争条件下喀斯特洞穴旅游竞争研究

在市场竞争条件下,即游客为经济人的情况下,同一地域内洞穴类旅游地的空间竞争表现为替代性强的空间竞争,其结果为区位好、资源价值高、知名度大的洞穴替代区位差、资源价值低、知名度小的洞穴.而在非市场竞争条件下,同一地域内的洞穴旅游地空间竞争结果受到旅游地内外部复杂环境因素的影响,表现为不确定性.企业经营因素、政策因素等有可能超越资源、区位、知名度等因素,对洞穴类旅游地间的空间竞争格局的形成发挥作用,导致市场的重新分配.     

The utility of livestock dung for reconstructing recent ethnological and environmental histories

Animal dung is evaluated here as a tool to reconstruct recent societal and environmental changes. Studies completed on the macro- and micro-contents from dung deposited in a mountain cave in Catalonia during the 1970–1980s, preceding the socio-economic changes in the area, was supplemented by the testimony of the last shepherd alive in the area. This information was also compared with evidence from aerial photographs of the area surrounding the cave taken in 1956 and 2009. Although taphonomic distortion of the dung shape precluded its assignment to its producers based on morphology, information from the organic remains reflects the agro-pastoral activities in the mountainous area of the Catalan coast. A lack of calcium phosphate and abundant phytolith and epidermal remains from wild species indicates that the dung was excreted by ovicaprines, who sheltered in the cave during spells of adverse weather. These indicators also signify that the animals fed only on natural vegetation. Insect remains in the dung include fragments of chafers, dung and ground beetles, bees and ants, and whilst the latter may have foraged in the cave, the others may have been accidentally ingested by herbivores. The nannofossils and diatoms found in the dung derive from tertiary crops 4 km away from the cave but within the range of the ovicaprine herd. The lack of cereal and vegetable remains in the dung is consistent with the ethnographic record that shepherds and farmers could not afford to supplement the herds’ diet with fodder crops or grain, a consequence of the low productivity of the local subsistence agriculture. This study further discusses the socio-economic impacts of the introduction of intensive farming, industrialisation and tourism in Catalonia during the latter part of the last century and how they are represented in the dung.     

Airborne LiDAR application to karstic areas: the example of Trieste province (north-eastern Italy) from prehistoric sites to Roman forts

The Trieste Karst, at the northernmost shore of the Adriatic Sea, is rich in prehistoric caves and protohistoric hill forts. Most of these archaeological sites were already identified in the second half of the 19th century when large parts of the area were almost without vegetation coverage for the effect of sheep breeding and exploitation of wood resources. Only a few open-air archaeological sites have been discovered in recent years due to the lack of systematic archaeological surveys and reforestation.     

多维贫困视角下的旅游扶贫与空间正义研究——以贵州施秉喀斯特世界遗产地社区为例

旅游扶贫作为促进贫困地区经济发展的主要手段,在产生经济效益的同时亦存在众多社会矛盾,然而以往研究更多强调主体利益,而未从空间的本质去探讨社会矛盾的表现及过程。本文从多维贫困视角,以施秉喀斯特世界遗产地的牌楼冲社区为例,通过深度访谈等研究方法,探讨旅游扶贫产生的空间非正义的问题。研究认为,旅游扶贫对社区产生的效应有经济收入增加但不均衡、村民参与旅游但机会不平等和旅游服务技能提升但参与能力欠缺三方面,这是由资源不公正分配、村民自主决策权缺失和社区参与边缘化等空间非正义过程导致的。本研究对中国传统乡村向旅游乡村转型的空间再组织过程中,由经济制度、旅游政策、资本、发展话语与实践所带来的社会冲突与风险提供了一个新的分析视角,也促进对旅游扶贫的效应及其空间正义问题的反思。

Cave sediments,upper pleistocene stratigraphy and mousterian facies in Cantabrian Spain

Archaeological sediments are analysed from karst cave columns in Cantabrian Spain: Cueva Morín, El Pendo, the Castillo cave complex (including La Flecha, Las Chimeneas, La Pasiega, Las Monedas), Hornos de la Peña and Cobalejos. External sediment influx, including loess, is calibrated by an index of cave and slope run-off energy, while other features (slope and roof rubble, chemical precipitates, cryoturbations, fine soil derivatives, and cultural components) are discussed. The key sequences (Morín, El Pendo, Castillo) are each interpreted in local terms and then combined into a regional climatostratigraphy that includes 40 environmental phases within deep-sea isotope stages 2–5. Trends in run-off energy (reflecting slope stability), temperature, and summer-moisture are rarely in phase, indicating complex environmental change. Mid-Pleistocene and older deposits exist but have largely been destroyed, explaining the apparent absence of Acheulian settlement. Mousterian occupation is verified by isotope stage 5b, and two or three Mousterian facies that span 25–50,000 years are coeval in several caves, regardless of the direction of climatic oscillations. This suggests the flexible lithic technology of a single population, maintaining an adaptive steady state despite repeated environmental changes. By contrast, the distinct upper palaeolithic industries each span only a few millennia, but in part overlap temporally within the region between 35,000 and 9500 bp.     

GPR survey at Lapa do Santo archaeological site,Lagoa Santa karstic region,Minas Gerais state,Brazil

In this work we present and discuss the results of a novel and timely GPR-2D and GPR-3D survey performed at an archaeological rock shelter site, Lapa do Santo, localized in the karstic region of Lagoa Santa, central Brazil. A total of 113 ground-penetrating radar profiles were acquired with 200 MHz and 400 MHz shielded antennas aiming in identifying geological and archaeological anomalies in order to assist archaeologists in an excavation program. The GPR results indicated clear geophysical anomalies characterized by hyperbolic reflections and areas with high amplitude sub-horizontal electromagnetic waves. The anomalies observed by GPR were confirmed by the excavation of test units, allowing the identification anthropogenic features such as a fire-hearth structure and wooden artifact, and natural features, such as, tree roots and rocky bodies such as speleothems, boulders and bedrock. The results showed the efficiency of GPR method in identifying potential buried archaeological targets in cave sites within a karstic area, and they oriented to archaeological excavations, reducing costs and increasing the probability of finding archaeological targets in the initial stages of a project.     

History of Deforestation and Reforestation in the Dinaric Karst

The term karst derives from the Kras plateau, which is in the northwestern part of the area now known as the Dinaric Karst. The landscape consists mostly of Mesozoic carbonate rocks and stretches along the Adriatic Sea coast for a distance of 600 km. Although the region lies parallel to the sea, the Mediterranean temperature influence is limited to a narrow coastal belt, except for the amount of precipitation, which can reach 5000 mm yr^?1. Forests belonging to the Mediterranean and Euro‐Siberian – North American region, covered the primary Dinaric Karst. Human deforestation of the Karst began during the Neolithic period, 6500–6000 BC. Throughout history there have been two main reasons for deforestation; economic (the requirements of new land, pastures, timber use and trade), and social (local increases in population, mass migration, wars, raids). Mankind's perception of forest protection and preservation can be traced through documents going back to the 12th century. Reforestation is mentioned in some of them, but successful reforestation did not begin until the 1850s. Nowadays dense natural forests, extensive forest plantations, dry karst shrublands and also completely barren karst areas can all be found on the Dinaric Karst.
