Study on the eco-geological vulnerability in Langfang area, Hebei Province

摘要: 以廊坊市南部七区县为研究对象,依托生态修复支撑调查项目数据,基于GIS技术,采用层次分析法对廊坊地区进行了生态脆弱性研究,提出生态保护修复与发展建议.研究表明,廊坊市南部七区县生态地质微度脆弱区的面积为1 742.85 km²,占总面积的33.83%;轻度脆弱区的面积为2 287.51 km²,占总面积的44.40%;中度脆弱区的面积为961.72 km²,占总面积的18.67%;高度脆弱区的面积为159.92 km²,占总面积的3.10%.

Abstract: Taking the seven districts and counties in southern Langfang City as the study area, this research assesses the ecological vulnerability of Langfang area and puts forward suggestions for ecological protection, restoration and development by way of GIS and AHP(analytic hierarchy process) on the basis of data from the ecological restoration survey projects. The results show that the slightly vulnerable zone covers 1 742.85 km², accounting for 33.83% of the total area, the mildly vulnerable zone 2 287.51 km² (44.40%), the moderately vulnerable zone 961.72 km² (18.67%), and the highly vulnerable zone 159.92 km² (3.10%).
