- Abstract:
-
Based on the actual situation of Hunan Province, this paper built the index system of land suitability comprehensive evaluation, and with the support of GIS technology, regression tree and kernel density estimation were used to extract and compute the evaluation factors, then the evaluation factor database was constructed. Based on the multiple criteria decision making (MCDM) framework, the weight of each factor was determined by using analytic hierarchy process (AHP), result of cultivated land suitability was achieved through weighted superposition method, and the cultivated land suitability could be divided into highly suitable, moderately suitable, marginally suitable and unsuitability, the proportions of four categories were 24.34%, 27.7%, 32.35%, 15.61%, respectively. Overall, cultivated land suitability distribution demonstrates that the suitability was strong in the east and weak in the west,the strong suitability areas are mainly located in the north of Dongting Lake Plain and the Xiangjiang River Plains, marginally suitable and unsuitable areas are mainly located in western, northwestern and southern mountain areas of Hu’nan Province.
