湖南省全域土地综合整治资源潜力调查分析评价

Survey,Analysis and Evaluation of Resources Potential of All Land Comprehensive Consolidation in Hunan

以湖南省20个全域土地综合整治试点区域为研究对象,采用资料收集、内业判读、外业调查核实等方法,利用限制因子评价法对宜耕土地后备资源潜力图斑进行区划和面积测算,对后备资源潜力的来源、地类和分布特征进行分析评价。结果表明:后备资源潜力以其他林地、坑塘水面、农村建设用地复垦为主;耕地后备资源来源存在明显的地域特征,平原湖区后备资源主要来源于坑塘和养殖坑塘,其他区域后备资源主要来源于其他林地和园地。最后对全域土地综合整治资源潜力调查和开发存在的问题进行了分析,并提出相应建议。

Taking 20 pilot areas for all land comprehensive consolidation in Hunan province as object of study,by using the data collection,indoor interpretation and field investigation and verification,etc.,and also using the limit factor evaluation method,the division and area measurement have been made to reserve resource potential map spots of appropriate tillage land.Then,the analysis and evaluation to the source,land type and distribution characteristics of reserve resource potential also performed.The results show that the reserve resource potential mainly includes other woodland,water surface of potholes and ponds,the reclaimed land from rural construction land;the reserve resources of cultivated land have obvious regional characteristics,the reserve resources of plain lake area are mainly from ponds and aquaculture ponds and the reserve resources of other areas are mainly from other woodlands and gardens.Finally,the paper analyzes the problems existing in the resource potential investigation and development of all land comprehensive consolidation and puts forward some relevant suggestions.
