Suitability evaluation and consolidation division of rural residential areas in villages and towns

Suitability evaluation of rural residential areas is the basis of land consolidation division. Taking Yuyue town and Guanqiao town as cases, the suitability evaluation indexes of rural residential areas were established based on three factors of nature, society and economy, ecology, and quantitative system and characterization of indexes were analyzed. The consolidation division of rural residential areas was realized by coordinating rural-urban development and suitability classification. The results showed that the difference of suitability was apparent between Yuyue and Guanqiao, and the suitability of rural residential areas in Yuyue town was higher than that of Guanqiao town. Converting from rural residential areas into town land should be regarded as key consolidation way in Yuyue town, while spatial migration for scattered rural residential areas was the main way in Guanqiao town. Consolidation areas and planning areas were well organized based on spatial integration among different division areas, which can provide decisive support for rural residential land consolidation.
