研究目的:识别生态安全受扰动地段,为区域生态安全生态修复与重建提供技术支撑。研究方法:利用2009年变更土地利用调查数据和生态限制因子分布图,借助GIS工具,定量分析与定性分析相结合。研究结果:基于人居生态安全修复面积为42.05km2,基于景观生态安全修复面积为4.46km2,基于文化生态安全的修复面积为2.96km2。研究结论:通过对多目标区域生态安全因子的分析,结合现状建设用地分布,识别基于人居生态安全、景观生态安全、文化生态安全的扰动地段,提出基于不同目标的区域生态安全生态修复利用类型与生态重建技术措施。
The purpose of this study was to identify the disturbance areas based on regional ecological security and to provide technical support for ecological restoration and reconstruction. Methods of GIS spatial analysis were employed to conduct qualitative and quantitative analysis with the dataset of land use and distribution of ecological factors in Fangshan District of Beijing. Main results were as follows. The disturbance area of habitat ecological security was 42.05 square kilometers, the disturbance area of landscape ecological security was 4.46 square kilometers, and the disturbance area of cultural ecological security was 2.96 square kilometers. It was concluded that the disturbance areas of habitat ecological security, landscape ecological security and cultural ecological security were identified through the multi-objective analysis on regional ecological security factors combined with the distribution of land type, and eventually the ecological reconstruction measures were proposed based on different goals of ecological restoration of regional ecological security.
