摘　　要：城镇近郊区生态敏感性分析是进行"空心村"整治与发展规划的基础性工作。根据城镇近郊区的基本特征,选取坡度、高程、植被、水系等4个评价因子,采用层次分析法确定评价因子权重,并将生态敏感性划分为5个等级,利用GIS空间分析功能获得实验区生态敏感性区域分布状况及相关统计数据。并根据城镇近郊区生态敏感性的分析结果讨论了"空心村"整治潜力。Ecological sensitivity analysis of suburban areas is the basic work of hollow village renovation and development plan.According to the basic characteristics of suburban areas,this paper chooses slope gradient,elevation,vegetation,water as four evaluation factors,uses AHP to determine the weights of evaluation factor and divides the ecological sensitivity into five levels,then exploits the GIS space analysis function to obtain the ecological sensitive area distribution and related statistical data of experimentation.Finally,this paper discusses the potential of the hollow village renovation according to the results of the analysis of the ecological sensitivity of the suburban area.
