2003年中国省域社会－经济－自然复合生态系统生态位评价

在借鉴可持续发展和宜居城市等评价方法的基础上,建立了一套社会-经济-自然复合生态系统生态位评价的指标体系.复合生态系统综合生态位包括资源、环境、经济和社会4个子系统生态位,而各子系统的生态位又包含若干单项评价指标.介绍了如何运用全排列多边形综合指数方法计算4个子系统的生态位和复合生态系统综合生态位,并对2003年中国31个省、自治区、直辖市的复合生态系统生态位做出了定量评价.结果表明:云南、海南、广西等省的资源生态位较高;海南、福建、湖北等省的环境生态位较高;上海、北京、浙江等省的经济生态位较高;上海、北京、天津等省市的社会生态位较高.综合生态位排在前三位的区域分别为广东、福建和海南.

Niche assessment of China provincial social-economic-natural complex ecosystems in 2003

Using the approaches of evaluating sustainable development and livable cities for references, a set of indicator systems were established to assess the ecological niche of complex ecosystem. The integrated ecological niche of complex ecosystem included 4 sub-niches of natural resources, environment, economy and society, and these sub-niches comprised many single-item indicators. How to apply the polygon synthesis indicators approach to calculate the integrated ecological niche and 4 sub-niches was introduced, and a quantitative assessment on the ecological niches of complex ecosystems in 31 provinces, autonomous regions, and municipalities directly under Central Government of China in 2003 was made. The results showed that Yunnan, Hainan and Guangxi had a higher sub-niche of natural resources, Hainan, Fujian and Hubei had a higher sub-niche of environment, Shanghai, Beijing and Zhejiang had a higher sub-niche of economy, and Shanghai, Beijing and Tianjin had a higher sub-niche of society. The integrated ecological niche in Guangdong, Fujian and Hainan was the highest.
