Impacts of the 2004 Tsunami on Surin Marine National Park,Thailand

The impacts of the tsunami in 2004 on the reefs in Surin Marine National Park, Thailand, varied with the location and exposure of the reefs. Channel areas between islands were severely damaged. Areas with steep reef slopes were damaged by sand slides or coral collapse more than areas with low slopes. Massive, sub-massive, and encrusting corals were more resistant and resilient to the direct impact of the tsunami than branching, tabulate, and foliose life forms whereas the latter were more tolerant of temporary coverage by sand. Sub-massive corals were the most tolerant overall and survived sand coverage, breakage, and overturning. Live coral cover measured three months after the tsunami was significantly greater than immediately post-tsunami as broken, moved, or sand-covered corals, recorded as impacted in the initial survey, had survived and were regenerating. Low turbidity, lack of pollution, and mild currents possibly contributed to rapid recovery and limited long-term effects of the tsunami. Impact assessment shortly after a major disturbance may give an initial measure of damage but subsequent surveys must be undertaken to identify long-term effects. Understanding patterns of reef damage can help to formulate reef zoning and protection strategies in response to catastrophic events, but also in advance of such events to improve likely resilience of the marine park to disturbance.     

Tragedy of the San Francisco bay commons

Abstract

Although the early efforts to save San Francisco Bay in the 1960's provided the role model for protection of California's 1100 mile ocean coastline, neither Proposition 20 of 1972 nor the California Coastal Act of 1976 provided any benefits to San Francisco Bay. One result is that the Bay is locked into its urban, shoreline‐use dominated plan of 1969 while every other estuary and coastal wetland in California receives much stronger protection of its resources. Furthermore, due to the complexity of California's water laws, there is no instream flow protection for receiving waters such as San Francisco Bay. This is particularly critical considering that 70% of the Bay's freshwater inflow has been diverted. The Bay's present decline as the largest and most important estuary on the West Coast, as well as its possible death as an estuary, may be irreversible. The problem requires the immediate attention of engineering, scientific, economic and legal disciplines if San Francisco Bay is to be saved.     

浅谈当前外派船员市场的可持续发展

文中通过对我国和国外船员发展情况现状的研究,分析我国海员外派存在的问题及原因,提出整改建议和发展方向,以便于船员市场能够可持续、健康地发展。     

基于生态足迹供给模型的区域可持续发展能力评价

区域环境影响评价乃至目前正大力推行的规划环境影响评价中区域规划的可持续能力的评价是个难点,现尝试借用生态足迹理论中生态足迹供给的模型,结合区域环境影响评价的具体实践,分析了其用于区域可持续能力评价的可行性,并以上海市青浦区重固镇的区域开发为案例进行了研究,结论认为:生态足迹供给模型是对区域开发的可持续能力进行评价的一个有效工具,但有关具体参数的选择还需结合当地实际进一步开展基础研究工作。
