摘要
随着人口增长及经济快速发展,江西省社会、经济、资源与环境之间矛盾日益突出。水生态承载力为一定条件能够承载的陆域生态发展、人口社会规模及经济发展水平的能力,对其研究可协调社会、经济、资源和环境之间的矛盾。基于对水生态承载力理论分析基础上建立江西省水生态承载力指标体系(压力层、支撑力层、弹性力层),结合层次分析法和模糊数学方法对1999～2008共10年江西省水生态承载力进行了分析。分析结果显示承载力10年都在中等水平范围内波动;江西省水生态承载力下降趋势由压力层主导,上升趋势由支撑力主导,波动趋势由弹性力主导。
Along with the rapid economic development and population growth,the contradictions among the society,economy,resources and environment in Jiangxi province have become increasing prominent.The water ecological carrying capacity is the ability to carry the terrestrial ecological,population and economic development.We attempted to coordinate this contradiction through evaluating it in this paper.We defined the indicators（i.e.,pressure layer,supportive layer,elastic layer） based on the theoreticalanalysis of the water ecological carrying capacity.Then the AHP and fuzzy math method was applied to study the ecological carrying capacity of water in Jiangxi province from 1999 to 2008.The results showed that the capacity was various in the moderate range in past 10 years.The pressure layer leaded to the trend of decline,whereas the rise trend was incurred by the supportive layer and the fluctuation trend resulted from the elastic layer.
