汪清县农村居民点用地整治潜力评价研究

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C_v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265.06 hm²，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。

Estimation of Rural Residential Land Consolidation Potential in Wangqing County

It is important to scientifically evaluate the rural residential land consolidation potential for the work of rural residential land consolidation in Wangqing County.Nine townships in Wangqing County was selecting as estimation units.We used the per capita construction land standard method to estimate theoretical potential of rural residential land consolidation of Wangqing County.The factors of consolidation will,consolidation ability and landscape fragmentation are selected to construct a comprehensive correction index system for the reclamation potential,and the theoretical potential is revised synthetically.Then natural,regional and land use structure factors are considered to construct a comprehensive estimation index system and evaluate its suitability.Based on ArcGIS 10.2 software platform,Voronoi diagram was generated to evaluate the new cultivated land potential and the new cultivated land coefficient of Wangqing County.At last,the new cultivated land potential was added as potential grading standard to divide cluster potential into four levels.The results show that:(1) the Cv value of rural residential land in Wangqing County is 134.82％ and the spatial distribution is cluster-type;(2) the new cultivated land potential is 265.06 hm2 and the new cultivated land coefficient is 6.33％;(3) the comprehensive correction coefficient of each township ranges between 0.15 and 0.65,the maximum appears in Dongguang Town and the minimum appears in Tianqiaoling Town;(4) It is suggested that the potential areas of Grade Ⅰ and Grade Ⅱ should be taken as key areas for consolidation,and the key points should be tapped to promote the land consolidation of rural settlements reasonably and orderly in Wangqing County.
