Abstract:

Suitability evaluation of villages’ construction land is the foundation of village land use planning, contributing to new rural construction and overall planning of city and countryside development. The author chose Huafang village in Chongqing Banan area as the research object. The method of minimum factors’ weight square was adopted to determine the index weight, using which weighted sum was calculated. Specifically, spatial analysis with GIS gave 4 levels of land suitability evaluation of the village: the best appropriate, the better appropriate, the appropriate and the non-appropriate. After that, the map of construction land suitability evaluation of the study region was drawn. The results showed that in Huafang village, Tianjing hill and the neighboring area were not suitable for construction layout, while Lizhi community, Chenjiazui community and Taoyuanzi community were relatively suitable for construction layout. On the whole, ‘Bayu New Village’ could be implemented in this village. Through the introduction of GIS technology, the scientific property and work efficiency were improved. Also, scientific basis was offered to improve the distribution of construction land.
