中文摘要	以攀枝花视野区为例,研究了基于GIS的干热河谷区植被恢复适宜性评价及分区方法.在干热河谷植被恢复适宜性评价及分区中,主要考虑对植被类型及植物生长影响较大的海拔高度、坡向、坡度、岩土类型、土层厚度等因素,并采用专家评分法给各影响因子权重和适宜性评价赋值.经过GIS的数据处理、空间分析、模型建立及运算,得到植被恢复适应性评价图,再经过分类、合并,将攀枝花市视野区划分为适宜区、较适宜区、较不适宜区、不适宜区、极不适宜区,得到植被恢复分区图.
英文摘要	Taking the view area of Panzhihua city as an example, the suitability appraisement and regionalization of vegetation rehabilitation was undertaken in the dry hot valley by using GIS technique. Thinking of the importance to vegetation growth and distribution, some factors were considered. They were the elevation, the aspect, the slope degredient, the soil depth and the lithological composition. The weighs and the suitability values of selected factors were given through expert method. Through data dealling, spatial analyzing and model establishing and data handling, the vegetation rehabilitation suitability map was obtained. After that, the value of suitability appraisement was reclassified and merged. The area of Vegetation rehabilitation was divided into five types: suitable zone, less suitable zone, less unsuitable zone, unsuitable zone and extreme unsuitable zone. In the end, the map of vegetation rehabilitation was gotten.
