【摘要】：海洋是生命的摇篮、人类的故乡、资源的宝库。海洋资源是人类社会实现可持续发展的宝贵财富。发展海洋产业是解决当今人类社会面临的人口膨胀、资源短缺和环境恶化等一系列问题的重要途径。但是,在海洋经济发展的同时,由于粗放式的开发方式及落后的生产技术使得海洋资源的掠夺性开发与沿海环境污染都很严重。海洋资源短缺、环境污染与生态破坏己成为今后海洋经济发展的主要限制性因素。因此,迫切需要深入开展海洋承载能力方面的研究,实施海洋的可持续发展战略。海域承载力就是这样一种能反映海洋人地关系可持续发展的定量化指标,它是海洋可持续发展重要的判断依据。本文借鉴有关海洋承载力的研究,以福建省沿海县域单元为研究对象,通过对海域承载力影响因素的分析,构架福建省沿海县市海域承载力评价指标体系,运用层次分析法确定指标权重,通过空间状态模型计算各海域的承载力得分,比较分析各县域单元海域承载状况的空间差异,并提出提高各海域承载力的相关对策。
[Abstract]:The ocean is the cradle of life, the hometown of mankind, the treasure-house of resources. The marine resources are the precious wealth for the sustainable development of human society. The development of marine industry is to solve the population expansion that human society is facing. An important approach to a series of problems, such as the shortage of resources and the deterioration of the environment. However, the development of marine economy is at the same time. Due to extensive development and backward production technology, the predatory exploitation of marine resources and coastal environmental pollution are very serious. Environmental pollution and ecological destruction have become the main restrictive factors of marine economic development in the future. Therefore, it is urgent to carry out in-depth research on marine carrying capacity. The carrying capacity of sea area is such a quantitative index which can reflect the sustainable development of the relationship between man and land, and it is an important basis for judging the sustainable development of the ocean. Based on the study of marine carrying capacity, this paper takes the coastal county area unit of Fujian Province as the research object, through the analysis of the influencing factors of the sea area carrying capacity, sets up the evaluation index system of the coastal county sea area carrying capacity in Fujian Province. Analytic hierarchy process (AHP) is used to determine the index weight and the spatial state model is used to calculate the bearing capacity score of each sea area and to compare and analyze the spatial difference of the carrying capacity of each county unit. And put forward the relevant countermeasures to improve the carrying capacity of each sea area.
