安徽省宣城市农村居民点用地整理潜力研究

Land Use Readjustment Potentials of Rural Settlements in Xuancheng

以乡镇为单位,在对宣城市农村居民点用地整理潜力调查的基础上,采用定性分析和定量计算相结合的方法,对农村居民点用地整理潜力的测算方法进行了研究,并运用系统聚类法对整理潜力进行分级、分区;针对各类型区,结合实际情况提出不同的整理模式。结果表明,全市农村居民点用地整理总潜力为12126.70hm^2,占待整理居民点用地面积的29.69%。其中,Ⅰ级整理潜力7812.37hm^2,主要分布在平原圩区;Ⅱ级整理潜力3612.40hm^2,主要分布在丘陵、岗地地区;Ⅲ级整理潜力701.93hm^2,以深丘、山地为主。

By using qualitative analysis and quantitative calculation in combination on the basis of investigations of land use readjustment potentials of rural settlements, approaches to measuring land use readjustment potentials of rural settlements in Xuancheng were discussed. And clustering analysis was adopted to grade and zone the potentials, and the models were established for collating the potentials in light of the specific conditions of each type zones. Results showed that the total potential of the rural settlements was 12126.70 hm2, accounting for 29.69 percent of the total land area of the settlements. Grade I potential was 7812.37 hm2, distributed mainly in the plain region; Grade II potential was 3612.40 hm2, mainly in the hilly region; and Grade III potential was 701.93 hm2, in the mountainous region.
