低山丘陵区耕地空间结构适宜度评价及优化配置研究—以平阴县为例

山地丘陵类地区耕地的优化研究,对农业发展的基础作用具有重要意义.为此,提出了耕地"空间结构适宜度"定量评价模型,在适宜性评价成果及土地利用现状数据库的基础上,根据生产能力差异,利用层次分析法构建不同耕地类型在不同适宜级别的均衡因子矩阵,从而建立了空间结构适宜度模型.选取具有典型低山丘陵特征的平阴县为研究区进行实证研究,结果表明,该模型能够较好地评价当前耕地空间结构的合理性.在此基础上,进行耕地的空间优化配置研究,以期实现生态效益和经济效益的最大化.

Spatial Structure Suitability and Allocation of Arable Land in Hilly Region in Pingyin County

There are many hilly regions in our country; the research where is significant to the agricultural development. The paper proposed evaluating model of spatial structure suitability of arable land. Based on the suitability evaluation results and the land use condition database, a balancing factors matrix of different kinds of arable land in suitability grades with AHP according to productivity, the author build the evaluating model of spatial structure suitability. Taking the Pingyin County as study area, result shows that the model is useful to evaluate rationality of spatial structure of arable land. Then study the spatial optimization and allocation of arable land, aim to the maximization of ecology and economy efficiency finally.
