摘要/Abstract

摘要： 以生态岛建设为政策前提，建立了崇明岛区生态承载力评价指标体系，包括1个总目标、3个分目标和41个具体指标。根据崇明岛区1998—2004年统计年鉴与2005—2006年实际调查数据，建立了评价指标体系，并利用层次分析（AHP）法确定权重，运用状态空间模型评价历年生态承载力，利用GIS空间插值对数据进行了空间量化与生态承载力空间分异分析。结果表明：崇明岛区生态承载力总体处于可载水平，从3个分目标层看，环境纳污能力与资源供给能力较好，但人类支持能力较差；崇明岛区各功能区生态承载状况有明显差异，可根据各分区实际承载情况，发展不同特色产业。

Abstract: According to the policy-decision of ecological island construction, and based on the 1998〖KG-*2〗-〖KG-*7〗2004 statistic yearbooks of Chongming Island and the investigation in 2005〖KG-*2〗-〖KG-*7〗2006, the evaluation index system of ecological carrying capacity of Chongming Island, Shanghai was established, which included one overall objective, 3 sub-objectives, and 41 indices. AHP method was used to evaluate the weights, State-Space Model was used to calculate ecological carrying capacity, and GIS spatial interpolation was used to analyze the spatial differentiation of ecological carrying capacity. The results showed that the overall ecological carrying capacity of Chongming Island was high, the environmental carrying capacity and resources supplying ability were good, while the human supporting ability was bad. Different function areas had different ecological carrying capacity, and various industries should be developed in accordance with their own practical status.
