Spatial Diffusion of Characteristic Planting in Less Developed Rural Areas:A Case of Daying Village,Henan Province
以河南大营村萝卜特色种植为例，分析了其空间扩散轨迹、模式及影响因素，发现扩散呈波浪式且存在距离衰减效应，空间结构为极轴模式。
The diffusion of agricultural innovation could call into its full play to the utmost extent in the sense of economy development,only on condition that it is sufficiently spread.As to the case study of Daying Village,Gushi County,Xinyang City,Henan Province,this paper analyzes the advantages of radish characteristic planting in Daying Village,reveals the track of the spatial spread of characteristic planting with reference to the innovation diffusion theory,summarizes the spatial diffusion pattern and its structure,and probes into the factors affecting the diffusion of characteristic planting in Daying Village.The conclusions are drawn as follows:(1) Daying Village's industrial selection of radish characteristic planting has strengths such as a natural resource endowment,a long history of cultivation,a strong market demand and so on;(2) Daying Village's radish planting spreads spatially in the wavy manner,and there apparently exists distance decay effect;(3) The spatial structure of Daying Village's radish planting diffusion takes place in the form of pole-axis mode,and the layout of planting bases have a significant Thunen ring imprint;(4) Daying Village's radish planting diffusion falls under the influence of spatial distance,geographical environment,the benefits of proliferation,government's effect and other factors.
