| 摘 要： | 区域森林火灾的人为干扰主要分为人为负干扰和人为正干扰。通过基于GIS的空间分析方法,对人为火源的危险程度和人为正干扰的影响进行了分析与评价,确定了人为负干扰火险指标为农事烧荒、农事炼山造林、上坟、旅游与基本活动,人为正干扰火险指标为投入人力和投入资金,并确定了指标权重、指标度量算法和评价模型,并在实验区进行了验证,以火险等级区划图的形式进行了结果评价。

| Abstract: | Human activities to regional forest fire have both positive and negative impacts.The negative one is mainly the source of forest fire.The positive ones include manpower,resources and funds,popularization,population quality and the construction of shelter belts.Analysis and evaluation on forest fire danger by human activities based on spatial analysis of GIS,resulted that the negative forest fire indicators of human activities were like burning the grass on waste land,broadcast burning and preparation for forestation,visiting grave,tourism and common activities,while the positive indicators include input of manpower and fund.Weight and value of indicators were verified,and evaluation model was established,and were proved in experimental area. |

| Keywords: | negative and positive impact of human activity forest fire danger rating spatial analysis of GIS evaluation model |
