生态文明导向下的小尺度农村居民点整理——以甘肃省渭源县清源镇为例

Rural Residential Land Consolidation Under Concept of Ecological Civilization——A Case Study at Qingyuan Town,Weiyuan County of Gansu Province

[目的]分析小尺度农村居民点的整理潜力、整理能力,为类似区域农村居民点整理提供参考依据。[方法]以甘肃省渭源县清源镇的25个行政村为研究对象,以2010年土地利用变更调查库数据为基础,采用Yaaph层次分析、聚类分析等方法,结合ArcGIS软件,对清源镇农村居民点的整理潜力、整理能力进行测算。[结果]清源镇农村居民点的整理潜力为330.063hm^2;选取生态条件、生产条件和生活条件等3方面的8个指标,构建修正指标体系,得出其整理能力为186.561hm^2,潜力释放水平为56.52%。25个村中,上磨村整理潜力最大,北关村、柯寨村和秦王村3个村不具备整理潜力,结合修正系数,将农村居民点整理潜力分为4级。[结论]根据整理潜力、整理能力及潜力修正系数,提出保留模式、并点模式、缩减模式和集聚模式等4种整理模式。

[Objective]To analyze the consolidation potential and capacity of rural residential land at a small scale in order to provide references for the rural residential land consolidation.[Methods]Taking 25 administrative villages in Weiyuan County,Gansu Province as the research objects,we estimated the consolidation potential and capability of rural resident.The land use data surveyed in 2010 was collected,the analytical hierarchy process and clustering analysis method was used,and ArcGIS software was employed.[Results]The consolidation potentiality area in Qingyuan Town was 330.063hm2.Under the concept of ecological civilization,8indicators covering ecological conditions,production conditions and living conditions were selected to construct the modified index system.The consolidation capability showed that the potential consolidation area was 186.561hm2,and the potential release level was 56.52%.Among the 25 villages,the consolidation potentiality in Shangmo village was the greatest,while the consolidation potentiality in Beiguan,Kezhai and Qinwang villages was the least.[Conclusion]According to the consolidation potentiality and correction coefficient,the consolidation capability of rural residential can be divided into 4modes,including retained mode,merged mode,reduction mode and agglomeration mode.
