【摘要】：探索耕地资源贫困状态,揭示耕地资源贫困在空间上的集聚与异化,对整治耕地资源与提高利用效益具有重要意义。该文在引入"耕地资源贫困"概念的基础上,通过构建农村耕地资源贫困测度评价指标体系与耕地资源贫困指数模型,运用动态层次分析法和空间自相关分析,对重庆市37个区县的耕地资源贫困程度以及在空间上的集聚与异化进行研究。结果表明,时间序列上,重庆市耕地资源贫困程度不断降低,各区县贫困程度差距巨大但逐年不断缩小;空间分布上,耕地资源贫困程度呈现出渝东北渝东南城市新区主城区的特征,并且贫困程度高值区域由渝东南向渝东北转移,贫困程度低值区域由主城区向城市发展新区扩散;空间关联上,重庆市耕地资源贫困呈现出显著的空间集聚效益,高值中心集聚于渝东南和渝东北,低值中心集聚于主城及城市发展新区。
[Abstract]:Exploring the poverty state of cultivated land resources and revealing the agglomeration and alienation of cultivated land resources poverty in space is of great significance to renovate cultivated land resources and improve utilization efficiency. On the basis of introducing the concept of "cultivated land resource poverty", this paper constructs the evaluation index system of rural cultivated land resource poverty and the model of cultivated land resource poverty index, and applies dynamic analytic hierarchy process and spatial autocorrelation analysis. This paper studies the poverty degree of cultivated land resources and spatial agglomeration and alienation in 37 districts and counties of Chongqing. The results show that, in time series, the degree of poverty of cultivated land resources in Chongqing is decreasing, the disparity of poverty in different districts and counties is huge but decreasing year by year, and the spatial distribution, The poverty degree of cultivated land resources shows the characteristics of the main urban area of the new urban area of southeast Chongqing in northeast Chongqing, and the high value region of poverty degree transfers from southeast Chongqing to northeast Chongqing, and the low value region of poverty degree spreads from the main urban area to the new area of urban development. The poverty of cultivated land resources in Chongqing presents remarkable spatial agglomeration benefits, with high value centers concentrated in southeast Chongqing and northeast Chongqing, and low value centers in main cities and new urban development areas.
