崇明生态岛生态环境评价及指标优化分析

崇明岛拥有良好的生态环境和丰富的自然资源,是上海可持续发展的储备空间。基于PSR模型构建了一套包含1目标3要素22项评价指标的崇明岛生态环境评价指标体系,并通过对评价指标归一化处理和各要素层指数权重计算,得出崇明生态环境指数。结果表明:在崇明生态岛建设行动计划的实施下,崇明岛生态环境指数从2008年的0.57增长至2015年的0.91,增幅达60%,生态岛建设进程从启动阶段进入发展阶段并逐步向完善阶段过渡,环境保护成效显著,可持续健康发展模式已经形成。同时,在分析评估近几年环境状况的基础上,对6项评价指标进行优化研究,以期更科学准确地反映崇明岛生态环境质量,为崇明岛生态文明建设提供依据。

Ecological environment evaluation and index optimization analysis of Chongming Eco-island

Chongming Island has a good ecological environment and abundant natural resources, which is the reserve space of sustainable development in Shanghai. Based on the PSR model, this paper constructed Chongming island ecological environment evaluation index system, which contained 1 target, 3 elements and 22 evaluation indexes. Chongming island ecological environment index was obtained by the normalization of evaluation index and the weight calculation of each factor layer. Results show that, due to the implementation of Chongming ecological island construction plan, Chongming island ecological environment index showed a trend of increased from 0.57 by 2008 to 0.91 by 2015, the growth rate reached 60%, and ecological island construction process gradually tend to reach perfection, environmental protection had achieved remarkable results, and the sustainable and healthy development mode had been formed. In addition, the index optimization analysis provided data support and policy suggestion for Chongming ecological civilization construction, which based on environmental evaluation in recent years.
