内蒙古农业资源利用区域差异分析

从农业资源利用的区域差异性分析入手,文章以内蒙古12个盟(市)为研究样本,从农业资源、农业生态压力、农业生态保护、农业经济及社会发展等5个方面,选择18个评价指标,运用因子分析方法确定权重,测算农业资源利用综合指数,分析各盟(市)农业资源利用的差异,进而对因子分析结果进行聚类分析,辨别内蒙古农业资源利用的区域相似性。结果表明:(1)从农业发展因子得分来看,通辽市、呼伦贝尔市、赤峰市及兴安盟分别为1.870、1.275、1.136及0.165,是内蒙古农畜产品生产基地,内蒙古农业资源保护的核心区域;(2)从草地利用因子得分来看,呼伦贝尔市、锡林郭勒盟、鄂尔多斯市及阿拉善盟分别为1.834、1.372、0.279及1.443,是内蒙古草原生态保护的重点区域;(3)从社会发展因子得分来看,呼和浩特市、包头市、鄂尔多斯市及乌海市分别为0.906、1.342、1.493及0.401,是内蒙古经济高速发展区域,其农业资源保护面临双重压力。基于此农业资源利用相似性较高的区域可以分为3类,分别是农业主产区、经济高速发展区、草地生态保护区。

ANALYSIS OF THE REGIONAL DIFFERENCE OF AGRICULTURAL RESOURCES UTILIZATION IN INNER MONGOLIA

Taking 12 leagues and cities in Inner Mongolia as research sample, this paper analyzed the regional differences of agricultural resources utilization based on 18 evaluation indexes, which were chosen from 5 aspects such as agricultural resources, agro-ecology stress, agro-ecology protection, and the development of agricultural economy and society. Factor analysis was applied to determine the weight and calculate the comprehensive index of agricultural resources utilization, meanwhile the differences of agricultural resources utilization in every leagues and cities were analyzed and then the result of factor analysis were clustering analyzed. The regional similarities of agri-cultural resources utilization in Inner Mongolia were distinguished. The results showed that the agricultural develop-ment indexes of Tongliao City, HulunBuir City, Chifeng City and Xing'an League were 1. 870, 1. 272, 1. 136 and 0. 165, respectively, where were the production bases of agricultural and animal products and core areas of agricul-ture resources protection in Inner Mongolia. The grassland utilization scores of HulunBuir City, XilinGol League, Ordos City and Alashan, were 1. 834,1. 372,0. 279 and 1. 443, respectively, where were the key area of steppe e-cology protection in Inner Mongolia. The scores of social development factors were 0. 906, 1. 042, 1. 493 and 0. 401 , which were rapid development regions in Inner Mongolia and faced double pressures in agriculture resources protection. Based on these, the regions with high similarity in agricultural resources utilization could be divided into three categories, i. e. , agricultural heartland, rapid economic development area and grassland ecological reserve.
