摘要
生态环境承载力是区域可持续发展研究的重要内容。本研究结合海南省社会、经济、环境现状,构建压力-状态-响应(P-S-R)模型,选取27个指标构建海南省生态环境承载力评价指标体系,采用GIS空间分析法和模糊综合评价法,对海南省18个市县生态环境承载力的时空差异进行研究。研究结果表明:(1)海南省生态环境状况较好,生态环境承载力的整体水平较高;(2)随着社会经济的发展,绝大部分市县的Ⅰ级隶属度值不断增大,生态环境承载力整体呈现不断上升的趋势;(3)从各市县的对比分析来看,海南省各市县的生态环境承载力呈现东部-中西部-北部递减的态势。
The eco-environmental carrying capacity is a critical part of the study on regional sustainable development. Combining social, economic and environmental status of Hainan Province, the authors constructed the pressure-state-response (P-S-R) model, selected 27 indicators to build the evaluation index system of ecological environment carrying capacity in Hainan and used the method of GIS spatial analysis and fuzzy comprehensive evaluation to study the temporal and spatial differences of ecological environment carrying capacity of 18 cities and counties in Hainan. The results showed that (1) the eco-environmental carrying capacity in Hainan was better than that in other provinces and the overall level of it was relatively high; (2) with the social and economic development, the membership value of Level I in most cities and counties increased, and the overall carrying capacity of ecological environment showed a rising trend; (3) the coo-environmental carrying capacity of cities and counties in Hainan showed a declining tendency from east to mid-west, then to north.
