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。 相似文献

As a major contributor to local economies, the tourism industry has been greatly impacted by natural disasters. This study demonstrates the association between tourism economies and impacts of hurricanes in the southeastern United States containing coastal national parks, known for attracting a large number of tourists and having experienced hurricanes. In keeping with two longitudinal data methods (i.e. panel logit model and autoregressive integrated moving average), this study focused on the relationship between the (1) duration, intensity, and damage of hurricanes; (2) existing climate conditions; and (3) tourism demand on park visitation during hurricane and tourism seasons. As a whole, the impacts of hurricanes and climate conditions (precipitation, temperature) were found to have a negative effect on tourism demands (park visitation). With regard to the response of tourism economies to natural disaster damage, parks that experienced stronger natural disasters may be closed for a longer period in order to reconstruct facilities or natural/cultural resources damaged by storms. In an attempt to improve tourism-based regional economies, overcome the challenge of natural disasters on tourism economies, and increase opportunities for establishing disaster management, it is necessary to make an effort to allay unexpected damage to tourism-based areas through proactive plans for disaster mitigation activities. 相似文献

Whales have long been an important part of Pacific Northwest Coast human subsistence and lifeways. Native peoples on the Oregon Coast were not known to hunt whales, but a humpback whale phalange with an embedded bone harpoon at the Par-Tee site (35CLT20) and ethnographic accounts raised the possibility of opportunistic whale hunting. We analyzed a suite of whale remains from Par-Tee and performed ancient DNA-based species identifications on 30 specimens. The assemblage includes gray whales (Eschrichtius robustus, 60.7% of the assemblage), humpbacks (Megaptera novaeangliae, 32.1%), minkes (Balaenoptera acutorostrata, 3.6%), and orcas (Orcinus orca, 3.6%). While the species composition is similar to those found in archaeological deposits from systematic whaling areas in Washington and Vancouver Island, bone modification patterns and element representation reveal important differences. Our analysis demonstrates that whales were likely a supplementary part of human subsistence at Par-Tee and, while opportunistic whale hunting likely occurred, it may have been secondary to scavenging and utilization of beached and/or drift whales. 相似文献

This article explores how residents of a small coastal fishing enclave in Colombo live with cumulative waves of dispossession brought on by exclusionary projects of urban development. Drawing on ethnographic fieldwork, I introduce the analytic of navigation to describe how people move, plan and live with both present and future threats of dispossession. Navigation offers a unique perspective on questions of agency and resistance in oppressive conditions. Rather than framing subjects as “resisting” projects of world-class city-making, this analysis shows that urban residents instead engage in complex and occasionally contradictory modes of living with uncertainty. I complicate existing understandings of the term “navigation” by describing how questions of nation and belonging are crucial to comprehending how people navigate. Ultimately, I suggest that expressions of belonging and obligation to an imagined community might not only be strategic, but instead reflect some of the broader social forces which structure possibilities for action. 相似文献

We here report the first results from a systematic research project in Mani (Southern Greece), which includes survey and test excavations. Forty-six caves, rockshelters and open-air sites in lowland settings were surveyed. Geomorphological data were collected in order to assess how geological processes affect the preservation of sites and bias site distribution patterns. Artifacts manufactured from non-local rock indicate potential raw material transfers and suggest links among the different regions of Mani, related to mobility patterns. Our research in the Mani has nearly doubled the number of known Middle Palaeolithic sites from the region and confirmed that the peninsula has the strongest ‘Neanderthal signal’ identified to date in Greece. Almost all sites are located at coastal areas. Despite the influence of Pleistocene landscape dynamics, this distribution emerges as a persistent pattern, perhaps indicating a preference for coastal locations. The Neanderthal occupation of Mani can illuminate important aspects of Middle Palaeolithic adaptation in one of the southernmost coastal regions of Europe. 相似文献

Southern Brazilian prehistoric coastal series were examined for the presence of spondylolysis. All defects occurred at the pars interarticularis, most at L5 (51%), with the vast majority bilateral and complete (86.2%). Frequencies decreased from young adulthood (54.2%) through mid‐adulthood (33.3%) to older adulthood (12.5%), suggesting differential mortality among affected individuals. The high overall prevalence (29.6%) demonstrates that these groups experienced a strenuous lifestyle, with activities that required repetitive and vigorous movements of lumbar hyperextension and rotation. Archaeological data provide support to interpret this pattern. Throwing harpoons, rowing and wrestling fishing nets were likely the main activities associated with the defect among men. Continuous loading of weight, including plant resources, mollusks and nursing children, were probably the tasks associated with spondylolysis in women. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献
