【摘要】：隨著沿海城市經濟快速發(fā)展,海洋資源消耗、海洋環(huán)境污染和海洋生態(tài)破壞等問題日益突出。作為衡量海洋可持續(xù)發(fā)展的主要手段之一,承載力的量化研究至關重要。本研究基于"壓力-狀態(tài)-響應"(PS-R)概念模型,構建了海洋生態(tài)環(huán)境承載力評價指標體系;運用主成分分析法(PCA)、熵值法和等權重法對評價指標分別賦權,建立了狀態(tài)空間評價模型,并以深圳東部海域為例對生態(tài)環(huán)境承載狀況進行實證分析,得出深圳東部海域超載的主要原因,為海洋資源的可持續(xù)利用提供科學依據。
[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.
