摘　　要：以济南小清河流域为研究区域,通过选择有代表性的生态影响因子,采用GIS技术和层次分析法对小清河流域进行生态敏感性分析,为小清河流域生态环境保护和开发利用提供依据。结果表明,济南小清河流域生态敏感性在空间分布上呈显著差异,敏感区主要分布在小清河上游、干流、玉清湖水库及其周边、白云湖以及南部山区,面积约487.0km^2,占流域面积的18.1%;轻度敏感区主要分布在敏感区外围,面积约1 173.7km^2,占流域面积的43.7%;不敏感区主要分布在平原区,距离水体一定范围以外的区域,面积约1 025.4km^2,占流域面积的38.2%。济南小清河流域总体生态敏感性一般,以轻度敏感性和不敏感性为主。In this paper,the Xiaoqinghe River Basin in Jinan,Shandong Province was chosen as the main study area to investigate the ecological sensitivity of the region,and to provide the basis for the ecological environment protection and reasonable utilization.Based on essential characteristic analysis,including ecological environment and resource utilization,taking typical ecological factors with the combination of geographical information system（GIS）and analytical hierarchy process（AHP）,the eco-environmental sensitivity of the basin was analyzed.The spatial distribution to ecological sensitivity of the basin was significantly different.The sensitive zone,with an area of 487.0km^2,accounting for 18.1% of the total,was mainly distributed in mainstream and upstream of Xiaoqinghe River,Baiyun Lake,the southern mountainous areas.Lower sensitivity zone,with an area of 1 173.7km2,43.7% of the total,was mainly distributed in the areas nearby the sensitive zone.Non-sensitive zone,with an area of 1 025.4km2,38.2% of the total,was mainly distributed in the plain areas.It was concluded that the eco-sensitivity of Xiaoqinghe River Basin was moderate,ranged between sensitivity and insensitivity.
