海洋生态岛建设评价方法研究与应用以崇明岛为例

在界定生态岛概念和借鉴国内外相关研究成果基础上,基于均权法,以集约节约、环境友好、经济发展、社会和谐、科技创新作为五大目标层,确定了49个基础指标,构建海洋生态岛建设指标体系,并以崇明岛为评价对象,结合资料收集情况,选取出36个指标评价其生态文明建设情况。结果显示,在崇明海洋生态岛建设中,森林覆盖率、COD排放强度等10项指标未达标,建设得分为0.925,评价结果为良。评价结果与崇明岛现实情况较为一致,说明本文构建的评价方法体系具有良好的显示性和适用性。

Research and application of evaluation method for marine ecological island construction-a case study of Chongming Island

Based on the definition of the connotation of marine ecological island and draw lessons from the related research domestic and foreign, this article build aevaluation framework of marine ecological islands construction. Five target layers for marine ecological island construction index system are established, based on averaging weight method, island characteristics and the situation of socio-economic development: intensive conservation, environment-friendly, economic development, social harmony and scientific, and technological innovation. Concretely, thematic layers are established based on 49 basic indicators to characterize the thematic condition. Finally, an application example is showed out. We choose Chongming Island as the object of evaluation, 36 indicators were selected. The result shows that in the ecological island construction of Chongming, there are 10 indicators didn't reach the standard, like forest acreage, COD emission intensity, etc. The synthesize score is 0.925. The evaluation results are consistentto the fact of ChongmingIsland which mean that the evaluation system has good revelation and applicability.
