基于Topsis和矩阵法的山区农村居民点整治时序分区研究

Zoning and Time series of Mountain Rural Residential Land Consolidation Based on TOPSIS and Prioritization Matrix Method

深入开展农村居民点整治是改善山区生活质量、加快山区新农村建设的重要途径。以湖北省十堰市郧阳区为例,在村级尺度上建立了基于topsis法的山区农村居民点整治适宜性和紧迫性评价模型,并运用时间管理优先矩阵法对评价单元进行整治优先级的划分,最后结合山区农村居民点整治实践将郧阳区农村居民点整治划分为优先整治区、次先整治区、后先整治区和暂不整治区四个时序分区。结果表明:(1)山区农村居民点整治的适宜性和紧迫性呈现区域差异,并且在村级尺度上的区域差异较乡镇尺度上明显,这表明在村级尺度上开展农村居民点整治更加合理;(2)通过耦合整治的适宜性和紧迫性来划分的农村居民点四级整治时序分区更符合山区整治实际,对山区农村居民点整治工作具有一定的指导意义。

Residential land consolidation is one of important measures to improve the living condition, produc tion quality in the mountainous area and speed up the construction of new rural area. As a case of Yunyang County in Hubei Province, we established an evaluating model of residential land consolidation urgency and suitability, based on the Topsis method, and used the prioritization matrix to divide the unit priority of con solidation in the mountain village level scale. Finally, the county was divided into the top priority zone, the second priority zone, the third priority zone, and the last priority zone. The main conclusions are as follows. （1） The appropriateness and urgency of the mountain village consolidation show regional differences and the regional differences are more evident at the village scale than the township scale, suggesting that village con- solidation should be carried out on the village scale. （2） It is more consistent with the actual mountain resi dential land consolidation by coupling the appropriate and urgency to divide the village timing partition, with some guidance for the mountain village renovation work.
