沿海省市海洋/陆地生态服务价值估算及相互作用关系

Estimation and Interaction of Marine and Terrestrial Ecosystem Services Value in Coastal Provinces and Cities of China

指出了生态服务价值是人类直接或间接从生态系统得到的利益,陆地和海洋每年向人们提供了不菲的生态服务价值,但对于这一价值的估算缺少系统的方法和统一的口径。借鉴前人研究成果,构建了海洋和陆地生态服务价值的框架,以此估算了我国沿海11个省市的陆地和海洋生态服务价值,并从人均生态服务价值角度进行了分析,在此基础上探讨了海洋和陆地生态服务价值之间的协同/互竞关系。结果表明:人均陆地生态服务价值远大于海洋;通过Pearson相关系数和互竞指数的计算发现大多沿海省市的海洋和陆地生态服务价值呈显著的协同关系,少数呈不显著的互竞关系。

The value of ecological services refers to the benefits that human beings get directly or indirectly from the ecosystem, and both of land and sea provide us with valuable ecological services every year. However, the estimation of this value lacks systematic method and unified caliber. This paper used the previous research results to construct the framework of marine and terrestrial ecological service value to estimate the marine and terrestrial ecosystem services value in 11 coastal provinces and cities of China, and analyzed from per capita ecological service value. On this basis, the cooperative / competing relationship between marine and terrestrial ecosystem services value is discussed. The results show that the value of per capita terrestrial ecosystem services is far greater than that of the marine ecosystem services. Through the calculation of Pearson correlation coefficient and mutual competition index, it is found that the marine and terrestrial ecosystem services value of most coastal provinces and cities show a significant synergistic relationship, while a few of them show no significant inter competitive relationship.
