Abstract:: Taking Wulong County, Chongqing Municipality as a case, using the data of 25 m×25 m raster, based on the integrated use of GIS and RS technology, we built land suitability evaluation model for the Chinese mountainous town. The elasticity factors involved in the evaluation model include the distance from the town, the distance from the main road, elevation, the waviness of land surface, slope and the present situation of land use. The weighting elasticity factors were 0.253 3, 0.211 6, 0.093 0, 0.136 9, 0.206 9 and 0.098 3, respectively. The rigidity factors involved in the evaluation model include the basic farmland, the ecological land and the protected areas. According to integrated use of the data management and spatial analysis function of Arcgis 10.0 software, combing with the selection of evaluation factors, we established the land suitability evaluation database of Wulong County, and provided data support for the construction of Wulong County. The results showed that the suitable and slightly suitable land for construction areas were 46.78 and 70.11 km², respectively, percentages of total area was 1.62% and 2.43%, respectively.
