Abstract:: Land suitability evaluation of rural settlements plays an important role in construction of new rural area. In order to reasonably arrange the rural settlements in karst mountainous, Majiang County of Guizhou Province was taken as the example and six factors were chosen to establish the evaluation index system of rural settlements in karst mountains by the technology of GIS, which were the slope, distance from the river, distance from the road, distance from the farming, distance from the town and land use，and the land suitability of rural settlements was evaluated by using ArcGIS spatial analysis techniques. The results showed that the high suitability and the middle suitability were only 4.38% and 8.96%, while the low suitability and the non-suitability accounted for 45.48% and 41.18%, respectively; high suitability and middle suitability distributed in the surrounding town, riverside and roadside, which had relations with convenient traffic conditions, adequate water resource, flat terrain and the attraction of the town. Low suitability and non-suitability distributed in steep mountains, which had relations with lack of water, inconvenience of traffic conditions, farther distance from the town.
