【摘要】：以政府推动下逐渐发展起来的西峡县香菇产业为例,利用官方统计及调查数据,借助Arc GIS软件,分析了该县袋料香菇种植业的空间扩散现象,发现以下特征:(1)早期参与的村空间分布分散,晚期参与的村空间分布集聚;(2)初始参与强度相似的村空间分布分散;(3)当前生产规模较大和较小的村、专业化水平相近的村空间分布均显著集聚。构建指标体系,运用AMOS 21.0研究了政府对农业专业项目空间扩散的影响发现,政府对项目空间扩散的强度、速度和各村当前生产规模、专业化水平均具有显著正向影响(影响系数分别为0.438、0.213、0.459、0.815),但非政府因素(如地理、资源、经济背景等)改变了政府作用下专业项目空间扩散整齐划一的面状格局,使低水平均衡的空间分布逐渐被高水平集聚的空间格局所替代,出现了"面→点"的逆向空间扩散特征。
[Abstract]:Taking the lentinus edodes industry in Xixia county developed by the government as an example, using official statistics and investigation data and Arc GIS software, this paper analyzes the spatial diffusion phenomenon of lentinus edodes planting industry in this county. It was found that the spatial distribution of the villages involved in the early stage was scattered and the spatial distribution of the villages participating in the late stage was concentrated. (2) the spatial distribution of the villages with similar initial participation intensity was dispersed; 3) the spatial distribution of the villages with large and small production scale and similar specialization level are all agglomerated significantly, and the index system is constructed. AMOS 21.0 was used to study the influence of government on the spatial diffusion of agricultural specialty projects. It was found that the intensity, speed and current production scale of government to project spatial diffusion. The specialization level had a significant positive effect (the influence coefficient was 0.4380.2130.4590.459U, respectively), but the non-governmental factors (such as geography, resources). Economic background, etc.) has changed the plane pattern of spatial diffusion and uniformity of professional projects under the action of government, so that the spatial distribution of low level equilibrium is gradually replaced by the spatial pattern of high level agglomeration, and the "plane" appears. 鈫扵he characteristics of inverse spatial diffusion of points.

【正文快照】： 1引言“一村一品”“一县一业”的区域专业化、规模化生产实现的途径是多样的。专业项目在同一区域内的空间扩散应是区域专业化生产实现的途径之一,尤其对于受地理环境影响大的农业专业项目的空间扩散,在某种程度上可以促进农业专业化生产区域的形成。在影响农业专业项目空间
