摘要:
为了实现基本农田保护政策“优质集中”的具体要求，以湖北省团风县为例，首先基于耕地自然质量、水利基础设施、区位条件、空间形态构建了4个因素11个评价指标的评价指标体系以反映耕地质量的空间差异性，随后使用K均值聚类法对耕地的综合质量等级进行划分，建立了基于耕地质量和空间聚类的基本农田划定方法。结合上级下达的基本农田保护指标确定团风县入选基本农田的耕地面积为16 333 hm2，且相应的耕地质量总分值均大于76.21，团风县基本农田大多分布在长江沿岸平原区。通过使用基于多因素加权求和模型获得的基本农田划定结果对此种方法进行验证，并基于景观格局指数对两种方法进行对比分析，这种方法不仅可行，而且能更好地实现基本农田划定中的质优和集中的目标。
Abstract:
In order to achieve the goal of high quality and concentration of the basic farmland protection policy, we took Tuanfeng County as an example and put forward a new method of the demarcation of basic farmland based on cultivated land quality and spatial clustering. Firstly, in order to describe the quality of cultivated land, indexes for each land unit were constructed by four elements that consist of eleven factors based on the spatial difference of cultivated land natural quality, water conservancy facilities, location and space form. Then the quality of cultivated land was classified by using K means clustering method in spatial clustering. The results showed that the area of cultivated land selected as basic farmland in Tuanfeng County was determined to be 16 333 hectares based on the basic farmland protection objectives assigned by the superiors, and the scores of the corresponding quality of cultivated lands were greater than 76.21, in addition, the primary farmland of Tuanfeng County mostly distributed in the plains along the Changjiang River. Through verifying this method by using the result basic farmland demarcating based on multi-factor model of weighted summation, and introducing landscape pattern index to compare two methods, the proposed method is not only feasible, but also can more better achieve the goal of high quality and concentration of basic farmland demarcation.
