摘要
通过建立南宁市青秀山风景名胜区生态系统敏感性评价因子指标体系和利用AHP法确定评价因子权重,构建青秀山生态系统敏感性综合评价模型,采用ARCGIS的空间分析功能、因子叠加法和层次分析法生成6个生态因子评价结果图,即坡度因子图、坡向因子图、光照强度分析图、水域缓冲区分析图、高程分析图和植被现状图,得到了生态敏感性等级及面积比例:强敏感区273.11 hm2,所占比例为23.98%;中敏感区493.50 hm2,所占比例为43.33%;弱敏感区372.3 hm2,所占比例为32.69%。
The comprehensive evaluation model of Qingxiushan is set up by the establishment of the ecosystem sensitivity assessment factor index system and the application of AHP method to evaluate the weight of ecological factors.Based on the spatial analysis of GIS and the factors superposition analysis method and AHP method,the factors of slope,aspect,illumination intensity,hydrological regime,evaluation and present plants were analyzed and the their maps were constructed.After grading the ecological factors and determining the weight index,the conclusion is shown as bellow: strong sensitive area is 273.11 hm2,which accounted for 23.98 % of total area;medium sensitive area is 493.50 hm2,which accounted for 43.33 % of total area;weak sensitive area is 372.3 hm2,which accounted for 32.69 % of total area.
