摘要:
以湖南省为研究区，结合湖南省的实际情况，构建了耕地适宜性综合评价指标体系，在GIS技术的支持下，运用回归树、核密度等地理空间建模方法提取计算参评因子，在此基础上构建了评价因子数据库。基于多指标决策（MCDM）框架，利用层次分析法（AHP）确定各参评因子的权重，选择加权叠加法进行耕地适宜性综合分析，并将耕地适宜性分为高度适宜，中度适宜，勉强适宜和不适宜四类。在数量上，各适宜等级面积分别占湖南省面积的24.34%，27.70%，32.35%，15.61%；在空间分布上，湖南省耕地适宜性总体呈现东高西低的分布特点，高度适宜和中度适宜的地区主要分布在湘北洞庭湖平原以、湘江平原地区和湘中丘陵区盆地；勉强适宜和不适宜地区主要分布在湘西、湘西北、湘东南部分地区。
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.
