摘要
以实地调查的南阳市83个农业型专业村70多个属性数据为依据,利用ArcGIS软件予以空间可视化,可得如下结论:在农业型专业村属性方面,产值规模普遍偏小,产业类型以蔬菜种植、养殖为主,销售市场主要集中于省域内部,国内市场也占有一定比重;在专业村发展的时间演化方面,呈现明显的阶段性特征,产业结构也发生相应变化;在专业村分布的空间变化方面,由最初的最适宜农业区向山区、城区方向转移,并具有行政边缘化的特征,可以用空间界面理论予以诠释。
Specialized villages, as a mosaic of rural spatial economy, take an important role in rural development and lead the direction of rural economic change. The agricultural specialized village is an important kind of specialized villages, and has a longer expected result of rural development. We made an investigation of 120 specialized villages in the whole Nanyang city, and then selected 83 villages which were dominated by agriculture, and each village included more 70 indexes of their attribute data. The paper made some analyses of spatial distribution and change of these 83 agricultural specialized villages by use of the ArcGIS software. The conclusions were as the following： （1）The output value of agricultural specialized villages was smaller than the other types＇ specialized villages, including the industrial specialized villages, service industrial specialized villages and so on. The agricultural specialized villages gave priority to vegetable cultivation and breeding. The sale markets were focused on the inner Henan province, and the domestic market was also important. （2）In the aspect of the temporal evolution, the development of specialized villages had the outstanding periodic attributions which were identified by three different contents, and their industrial structure had the corresponding change. （3）In the aspect of the spatial evolution, the agricultural specialized villages occurred earlier, and the place was located in the better and appropriate regions, then moved to the direction of the mountain, or city, and some of agricultural specialized villages were located in the spatial interface among the administration regions. So, we could take the spatial interface theory as a better theory of interpreting the distribution and change reasons of agricultural specialized village development.
