摘　　要：生态敏感性评价是进行生态环境规划的一项重要措施,也是对区域进行划分的一种手段。文章通过对萝北县进行生态环境敏感性评价,应用“3S”技术法、系统学等方法对选取的6个环境因子进行环境敏感性评价,得出综合性环境敏感评价图。结果显示萝北县环境敏感等级分为5级非常敏感区、高度敏感区、中度敏感区、一般敏感区、不敏感区,分别占比9.89%、26.74%、20.72%、22.63%、20.01%。Ecological sensitivity assessment is an important measure for ecological environment planning and a method for regional division.The article evaluates the environmental sensitivity of Luobei County by applying the“3S”technology method,systematic method,AHP analytic method,and expert scoring method to evaluate the environmental sensitivity of the selected six environmental factors to obtain a comprehensive environment sensitivity evaluation chart.The results show that Luobei County's environmental sensitivity level is divided into 5 levels:very sensitive area,highly sensitive area,moderately sensitive area,general sensitive area,and insensitive area,which account for 9.89%,26.74%,20.72%,22.63%,and 20.01%respectively.
