Abstract:
Village classification is the basic work that guides the planning and layout of villages and the formulation of renovation and upgrading plans. Taking Songji Town in Suiyang District, Shangqiu City, Henan Province as an example, using the grey fixed-weight clustering method, combined with the farming radius of local farmers, the natural villages and administrative villages of the town were classified and studied. The results are as follows:(1) A village classification index system was constructed covering resource endowments, development level, location conditions, etc., and the corresponding gray fixed-weight whitening weight function for village classification was established. (2) Through investigation, the main methods of local agricultural mechanized production travel are electric motorcycles and tractors, and the maximum acceptable travel time is 15~20 minutes. From this, it is determined that the farming radius of the local villagers is 5000~6666m. (3) Based on the gray clustering and the requirements of avoiding the abandonment of cultivated land, the study area the 92 natural villages in the area are divided into 1 characteristic protection village, 3 suburban integration villages, 29 agglomeration and promotion villages, 38 renovation and improvement villages, and 21 relocation and relocation villages. (4) The comparison found, the classification results based on natural villages are more in line with the actual situation of the villages than the classification results based on administrative villages, and the classification results are more refined and accurate.
