金沙江干热河谷区是我国西南地区典型的生态脆弱区。以金沙江流域重要的干热河谷地段——云南省巧家县为例，在野外实地调查和综合分析的基础上，将巧家县干热河谷区划分为1个立地类型小区、2个立地类型组、8个立地类型。 通过对植被资源的调查分析，筛选出适合本区生长的25种植物，并将其与不同立地类型进行合理配置，以期为巧家植被恢复和生态环境建设提供科学依据。

The ecological environment of dry hot valley in Jinsha River is very fragile and difficult to rehabilitate its vegetation. With the ?method of field survey and comprehensive analysis, the typical dry hot valley at the Qiaojia County in Yunnan province, was taken as an example to study the site type and its vegetation resources. The Qiaojia dryhot valley region was divided into 1 site subarea, 2 site type groups and 8 site types. By means of investigating vegetation types and plant species, 25 plants suitable for rehabilitation were chosen, which were rationally collocated with different site types to provide scientific basis for the vegetation rehabilitation and ecological construction at Qiaojia County.
