摘  要:
以遥感影像和青秀山土地利用现状图为主要数据源,在GIS支持下获取土地利用、土地覆被、水域面积等数据。选择景观格局、生境多样性、破碎化作为分析因子,从系统结构和功能两方面对青秀山完整性状况进行定量化综合评价。研究结果显示,林地作为模地的优势度值为66.28%,优势度明显;林地多样性H的值为1.0633,占Hmax的76.70%,显示多样性良好;破碎化指数为0.0018,破碎化程度低;生态完整性指数为3.98,说明青秀山森林公园生态完整性良好。

摘  要:
Taking the landsat TM images and the present land use map of Qingxiu mountain as the basic information resources,getting the data of land using,land covering,water area by using GIS.Choosing the landscape pattern,Shonnon-Waver Diversity and fragmentation as analysising indicators,Developing a quantitative ecological integrity assessment from the perspective of sytem structure and function.The results showed that the dominance score of forest matrix was 66.28%,has an obvious advantage;the landscape diversity average score was 1.0633,accounting for thirty percent of the Hmax,has a good diversity;the landscape fragmentation score was 0.0018,fragmentation level was low;the ecological integrity index score was 3.98,it means that Qingxiu Mountain has a good ecological integrity.
