Suitability evaluation of rural residential areas is to realize the reasonable distribution of rural land, mining an important basis for land consolidation potential. Taking northern area of Wuchang as study case, the suitability evaluation index system was setup for rural residential land in typical grain-planting areas based on three factors of nature, economy and society and ecology.The indexes were quantified by combining with regional internal characteristics. The zoning plan of consolidation of residual areas was realized by comprehensive consideration of population urbanization influences according to the difference of the suitability evaluation and the regional pattern. The results showed that the suitability of rural residential areas ranged from 0 to 3.996 8 for 12 villages in northern Wuchang City, dominated with high and middle suitable classes, the proportion of low suitable and unsuitable classes was 5.02%, no highest suitable class existed. There were some rural residential areas need key consolidation. Villager relocation should be guided in parts of Xinglong, Yingchengzi, Minle and other villages, while village relocation should be considered positively for Bajiazi, Changbao and Niujia villages or town, the internal reform could be conducted in parts of Xinglong, Bajiazi and Weiguo villages on the basis of residential reservation. The above results can provide scientific bases for the consolidation planning of the regional residential land.
