- 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.
