基于熵值法的农村居民点节约集约用地评价——以河北省为例

Evaluation of Rural Residential Intensive Conservation Land Use Based on the Entropy Method——A Case of Hebei Province

随着河北省经济社会的快速发展,农村居民点人均用地量大、容积率低,已对经济社会发展构成了制约。以河北省136个县(市)的农村居民点为评价对象,以县域农村居民点为评价单元,探讨河北省经济社会发展与保护并举的节约集约用地路径,采用熵值法和多因素综合评价法确定指标权重和综合评价值,对农村居民点节约集约用地进行评价。结果显示,河北省农村居民点整体上节约集约用地水平不高,但呈现逐步提高的态势。针对研究结果,提出了制定节约集约用地标准;因地制宜地采取相应措施;加强多学科融合,在景观水平上进行整合;强化理论研究,构建合理的配套体系等在农村居民点节约集约用地中亟待解决的相应课题。

With the rapid development of economy and society in Hebei province,economic and social development is restricted by large amount of per capita rural residential land and low volume rate.In this paper,we evaluated rural settlements from 136 counties(cities) in Hebei province to explore the land saving and intensive use path for the development and protection of economy and society.The entropy method and multivariate comprehensive evaluation method were used to determine the index weight and the comprehensive evaluation value of rural residential land conservation and intensive use.The results showed that rural residential land saving and intensive utilization level was not high,but the situation was improving in Hebei province.Issues to be solved urgently were proposed such as developing rural residential intensive land conservation standards,taking appropriate measures under local conditions,strengthening multidisciplinary integration and landscape-level integration,strengthening theoretical research and establishing matching system to construct a reasonable economical and intensive land in rural settlements.
