Temporal-Spatial Evolution of Agricultural Specialized Villages Development:the Case of Nanyang City,Henan Province,China
研究了河南省南阳市83个农业专业化村庄的空间分布与时间演变，发现其产值低于工业和服务业专业化村庄，且分布受行政边界影响。
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.
