摘要

借助于统计学分析方法、Landsat7ETM+遥感影像解译及GIS综合评价手段,构建了相对生态压力比值REP、相对剩余生态容量值R REC及相对生态风险度指数RERI,对珠江三角洲快速城市化的典型城市佛山市进行了区域开发的生态承载力分析及生态风险度评价,揭示了佛山市域的生态安全总体态势及问题成因;并从区域可持续发展角度提出应重视在区域开发中尽可能科学合理地维护林地、湿地、农田、城市防护林带等自然及半自然景观要素的系统性与连续性,从宏观尺度上引导城市集聚并对城市化的不良生态后果予以积极预防和有效调控,从而降低城镇化的生态风险。

Abstract

Foshan city is the third biggest city in Guangdong province and typically one of the fast developing cities of Pearl River Delta,which has been one of the most prosperous economic zones but meanwhile one of the areas characterized with serious ecological degradation within China's coastal economic regions since the late 1970s.Therefore,Foshan was selected as a case for the study on ecological security situation during the recent rapid urbanization process.Based on statistical methodology,Landsat 7 ETM+ interpretation by remote sensing software and GIS based integrated assessment,the local ecological capacity assessment,which was calculated with REP(Relative Ecological Pressure)and RREC(Relative Residual Ecological Capacity),and the ecological risk assessment,which was calculated with RERI(Relative Ecological Risk Index),were performed to demonstrate the total environmental situation,ecological consequences and causes for Foshan regional development.Results show that among the various districts of Foshan the REP levels rank in decreasing order as Chanchen>Nanhai>Shunde>Gaoming>Sanshui,whereas the RREC levels rank in decreasing order as Chanchen<Nanhai<Shunde<Gaoming
