海洋生态环境承载力研究——以深圳东部海域为例

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"（P-S-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。

Research on marine eco-environmental carrying capacity -a case study in eastern coast ocean of Shenzhen

With the rapid economic development in coastal cities, problems such as marine resource consumption, environmental pollution, ecological damage have become increasingly serious.As one of the main means to evaluate the sustainable development of oceans, quantitative research of the eco-environmental carrying capacity is essential.Based on the "Pressure-State-Response" (P-S-R) conceptual model, this research established an evaluation indicator system of the marine eco-environmental carrying capacity.A State-Space evaluation model was constructed using the indicators which were empowered by the principal component analysis (PCA), entropy method and evaluation method in sequence.An empirical analysis of evaluating the eco-environmental carrying capacity of Shenzhen eastern coast ocean was conducted with the State-Space model with the main reasons for the state of overloading identified, which will provide a scientific basis for the sustainable use of marine resources.
