东北地区农业地域结构类型划分研究

基于东北地区农业生产的结构和功能特征，建立农业地域结构类型划分的指标体系。以185个县级行政区域为统计单元，运用因子聚类和GIS空间分析方法，依据农林牧渔等主要部门的构成比例和不同组合，将东北地区划分为农牧类、种植业类、牧农类、农牧渔类、林牧类和渔业类等6种类型；在此基础上，根据主要农作物结构、牲畜种类构成以及林系特征等进行识别，划分出24种亚类，为区域农业发展宏观决策和政策制定提供较为科学的依据。图2，表3，参12。

Types Division of Agricultrual Region Structure in Northeast China

According to the structural and function characters of agricultural region in northeast China, comprehensive index system of agricultural regional structure was established, which included two types of forty indexes. Taking 185 counties regions as the basic regional item, and using the methodology of factors analysis, cluster analysis and GIS spatial analysis, six structural types of agricultural regional were devised according to composition of farming, forestry, animal husbandry and fishery. Furthermore, twenty four subtypes were also devised according to the crop＇ s structure, animal＇ s types and forestry＇ s characters. The reasonable classification of agricultural regional structure not only contributes to optimal deployment of agriculture sources and coordination development among farming, forestry, animal husbandry and fishery, but also puts forward scientifically basis for agricultural development strategy and policies.
