长兴县与水相关的生态环境承载力评价

从与水相关的生态环境承载力的概念及内涵出发，构建包含水(土)资源系统、与水相关的生态环境系统、社会经济系统的指标体系框架。依据指标的精选原则，采用层次分析法，结合长兴县实际的水资源情况、与水相关的生态环境问题及社会经济发展特点，构建包括2个水资源指标、10个与水相关的生态环境指标、7个社会经济指标的长兴县与水相关的生态环境承载力评价指标体系。基于构建的指标体系，采用承载状态综合测度模型法评价得出长兴县2014年水资源余缺水平测度值为0.711 9、与水相关的生态环境质量测度值为0.880 8、社会经济水平测度值为0.850 6、综合测度值为0.820 7，说明长兴县2014年与水相关的生态环境承载状态总体上处于良好承载状态，结果与实际情况较为符合，验证了该评价体系的有效性。

Water-related eco-environmental carrying capacity evaluation index system in Changxing County

Based on the concept and connotation of water-related eco-environmental carrying capacity, in this study the index system framework was constructed, which included the water(soil)resource subsystem, the water-related eco-environmental subsystem and the socioeconomic subsystem. According to the indicator selection principle, the analytic hierarchy process combining with the actual water resources situation, water-related eco-environmental problems and socioeconomic development characteristics of Changxing County, the water-related eco-environmental carrying capacity evaluation index system was constructed, which included two water resource indicators, ten water-related eco-environmental indicators and seven socio-economic indicators. Based on the built index system, the evaluation results show that the water resources surplus and deficiency level estimating index was 0. 711 9, the water-related eco-environmental quality estimating index was 0. 880 8, socioeconomic level estimating index was 0. 850 6 and the comprehensive estimating index was 0. 820 7 by using the carrying status comprehensive evaluation model for the Changxing County in 2014. These results indicate that the water-related eco-environmental carrying status in Changxing County in 2014 was generally in a good carrying status, in line with the actual situation.
