EVALUATION OF NATURAL SUITABILITY FOR HUMAN SETTLEMENT OF ZUNYI REGION BASED ON GIS
利用GIS技术建立包含地形、植被、水文、气候的模型，评价遵义地区人居环境自然适宜性，发现大部分区域适宜居住，西北向东南适宜性递增。
In this paper,the evaluation model of natural suitability for human settlement including of relief degree of land surface,vegetation index,hydrology index,climate suitability is established based on Geographic Information System technique,the natural suitability and restrictive for human settlement in Zunyi region is evaluated systematically.The results showed that the human settlement of Zunyi region is suitability,the HEI of Zunyi region increases from northwest to southeast in general,which of 44.41% is generally suitable areas,54.13% is more suitable,small proportion is critical region;the natural condition for human settlement of Zunyi city is better,the restrictive of land surface,vegetation,hydrology and climate is not obvious,which of land surface is the strongest,vegetation is secondary.
