海洋生态环境承载力研究——以深圳东部海域为例
发布时间：2019-05-22 08:52
【摘要】：随着沿海城市经济快速发展,海洋资源消耗、海洋环境污染和海洋生态破坏等问题日益突出。作为衡量海洋可持续发展的主要手段之一,承载力的量化研究至关重要。本研究基于"压力-状态-响应"(PS-R)概念模型,构建了海洋生态环境承载力评价指标体系;运用主成分分析法(PCA)、熵值法和等权重法对评价指标分别赋权,建立了状态空间评价模型,并以深圳东部海域为例对生态环境承载状况进行实证分析,得出深圳东部海域超载的主要原因,为海洋资源的可持续利用提供科学依据。
[Abstract]:With the rapid economic development of coastal cities, the consumption of marine resources, marine environmental pollution and marine ecological damage have become increasingly prominent. As one of the main means to measure the sustainable development of the ocean, the quantitative study of bearing capacity is very important. In this study, based on the conceptual model of "pressure-state-response" (PS-R), the evaluation index system of marine ecological environment carrying capacity was constructed. The principal component analysis (PCA), entropy method and equal weight method are used to weight the evaluation indexes respectively, and the state space evaluation model is established, and the ecological environment carrying status is empirically analyzed by taking the eastern sea area of Shenzhen as an example. The main reasons of overload in the eastern part of Shenzhen are obtained, which provides scientific basis for the sustainable utilization of marine resources.
