农区农牧系统生产布局的区际空间转移分析方法及实例

Analysis method and case study on interzone spatial transfer of agricultural system production disposition in farming region

在理论分析的基础上 ,构建了农产品生产布局的空间转移定量分析的方法 ,并采用该方法对长江三角洲农产品生产布局的空间转移进行分析 .结果表明 ,长江三角洲种植业生产布局向外转移趋势明显 ,但养殖业生产布局在区际间没有出现明显的空间转移 .这表明养殖业生产的空间转移正处于一个临界期 ,区际间畜禽产品生产竞争激烈 .在实例分析的基础上 ,作者从理论上将农区农牧系统生产布局的区际空间转移归纳为外推型、稳定型和内聚型 3种基本类型 ,并讨论了空间转移类型与农业生产结构调整之间的关系 ,提出了长江三角洲农业生产结构调整的战略方向 .

Based on theoretical analysis, a quantitative method was put forward to analyze spatial transfer of agricultural production. With this method, the spatial trans fer of agricultural production disposition was analyzed all round in Yangtze del ta. The results showed that the spatial transfer trend of cropping system dispos ition to outer regions was very obvious, and that there was no visible transfer in animal husbandry system. This also showed that animal husbandry production wa s in one critical state, it was in intense competition between Yangtze delta and outer regions. According to the research case, the interzone spatial transfer o f agricultural production disposition were divided into three basic types(Outer motive type, Stable type, and Cohesive type)in theory, and the relationship be tween the types of interzone spatial transfer and the adjustment of agricultura l production structure was discussed. Finally, the authors advanced the adjustme nt stratagem of agricultural production structure in Yangtze delta.
