【摘要】：基于农村集体建设用地集约利用的内涵,构建了一套评价农村集体建设用地利用集约度的指标体系,并以江苏省苏南、苏中、苏北的12个行政村为例,采用灰色关联与主成分分析方法对各行政村集体建设用地利用的集约度进行了对比分析。分析结果表明:苏南地区的农村集体建设用地利用的集约度较高,而位于苏北地区的农村集体建设用地利用的集约度则相对较低,苏中地区在两者之间,整体上与江苏省区域经济的发展水平相符;从近郊与远郊的农村集体建设用地集约利用水平来看,两种评价方法测算的集约度虽有所差异,但两种方法对于近远郊的排序是基本一致的,呈现的趋势是近郊农村集体建设用地利用集约度高于远郊的。研究表明,两种方法所得的农村集体建设用地利用的集约度大致相似,在近郊远郊空间分布以及苏南、苏中、苏北的区域差异所呈现出的规律性,可为制定促进区域农村经济发展和提高农村建设用地的集约利用水平等相关的宏观政策提供参考依据。
[Abstract]:Based on the connotation of intensive utilization of rural collective construction land, this paper constructs a set of index system to evaluate the intensity of rural collective construction land use, and takes 12 administrative villages in southern Jiangsu, central Jiangsu and northern Jiangsu as examples. The intensive degree of collective construction land use in each administrative village is compared and analyzed by means of grey correlation and principal component analysis. The results show that the intensity of rural collective construction land use in southern Jiangsu is higher, while that in northern Jiangsu is relatively low, and that in central Jiangsu is between the two. On the whole, it is consistent with the development level of regional economy in Jiangsu Province. According to the intensive utilization level of rural collective construction land in suburbs and suburbs, although the intensity calculated by the two evaluation methods is different, the order of the two methods is basically the same for the suburbs. The trend is that the intensive use of rural collective construction land in the suburbs is higher than that in the suburbs. The results show that the intensity of rural collective construction land use obtained by the two methods is about the same, and the spatial distribution in the suburbs and the regional differences between southern Jiangsu, central Jiangsu and northern Jiangsu show the regularity. It can provide a reference for the formulation of macro policies to promote the development of regional rural economy and improve the intensive use of rural construction land.
