【摘要】：科学合理地测算汪清县农村居民点用地整治潜力,是为汪清县农村居民点用地整治工作的开展提供理论依据。以汪清县9个乡镇为评价单元,采用人均建设用地标准法测算汪清县农村居民点用地整治理论潜力,并选取整治意愿、整治能力和景观细碎化因素,构建腾退潜力综合修正指标体系,对理论潜力进行综合修正。然后综合考虑自然、区位和土地利用结构因素,构建综合评价指标体系进行适宜性评价,基于ArcGIS 10.2软件平台生成Voronoi图,测算汪清县各乡镇新增耕地潜力和新增耕地系数,最后以新增耕地潜力作为潜力分级标准,运用聚类分析法将整治潜力划分为4个级别。结果表明:(1)汪清县农村居民点用地Voronoi图的Cv值为134.82%,空间分布类型属于集群性;(2)汪清县农村居民点用地整治新增耕地潜力为265.06hm2,新增耕地系数为6.33%;(3)各乡镇综合修正系数介于0.15~0.65之间,东光镇综合修正系数最高,为0.65,天桥岭镇最低,为0.15;(4)建议将Ⅰ级和Ⅱ级潜力区作为整治重点区域,实施重点挖潜,合理有序地推进汪清县农村居民点用地整治工作。
[Abstract]:Scientific and reasonable calculation of rural residents Wangqing County land remediation potential, to provide a theoretical basis for carrying out rural residents Wangqing County land remediation work. In 9 villages and towns in Wangqing County as the evaluation unit, the use of rural residents to measure the standard method of Wangqing County construction land per capita in the whole theory of treating potential, and select the rectification willingness, ability and improvement of landscape fragmentation factors, construct a comprehensive index system of potential correction to vacate, comprehensive revision of the theoretical potential. Then considering the nature, location and land use structure factors, constructing a comprehensive evaluation index system to evaluate the suitability of Voronoi graph based on ArcGIS 10.2 software platform, the township of Wangqing County new cultivated land potential calculation and the new cultivated land coefficient, and finally to the new cultivated land potential as a potential classification standard, clustering analysis method is applied to the remediation potential is divided into 4 levels. The results showed that: (1) Rural residents Wangqing County Land Voronoi Cv value is 134.82%, the spatial distribution types belonging to clusters; (2) rural residents Wangqing County land remediation potential of new land for 265.06hm2 new arable land coefficient was 6.33%; (3) the township comprehensive correction coefficient between 0.15~0.65, Dong Guang Zhen comprehensive correction coefficient of the highest, 0.65, tianqiaoling town lowest, 0.15; (4) suggested that grade I and II as a potential area of improvement in key areas, the implementation of key potential, reasonable and orderly promotion of rural residents Wangqing County land remediation work.
