南水北调水源地乡村产业空间分异特征及影响因素分析——以丹江口库区十堰段为例

Analysis on the Spatial Differentiation Characteristics and Influencing Factors of Rural Industries in the Water Source Areas of the South-to-North Water Diversion Project: Taking the Shiyan Section of the Danjiangkou Reservoir Area as an Example

本文以丹江口水库湖北十堰段的两个县级行政区(郧阳区和丹江口市)为研究区域,基于乡村产业信息,利用量化方法,对乡村产业的空间特征进行研究,并分析其影响因素,继而通过OLS模型,量化影响因素的相关性。结果表明:该地区乡村产业总体呈现西北—东南走势,中东部地区密度较高,主体围绕库区主湖面分布;丹江口市“县—镇—村”空间结构特征明显,郧阳区仅在中心组团出现较强聚集,“镇—村”层面产业发展较为均质。量化验证后发现,人口密度及地形坡度对产业格局影响较大,邻水及交通优势村庄与产业发展在此地区未发现强相关性。最后,以乡镇为基本单元,结合前述分析及实地调研,划分4种镇乡镇发展类型,并尝试分类提出对应发展策略及建议。

This paper takes two county-level administrative regions(Yunyang District and Danjiangkou City) in the Shiyan section of Danjiangkou Reservoir as the research area, which is based on rural industry information and uses quantitative methods, to study the spatial characteristics of the rural industry and analyze influencing factors, then to quantify the correlation of influencing factors through the OLS model. The results show that the rural industries in this region generally present a northwest-southeast trend and have higher density in the central and eastern regions, which are distributed mainly around the main lake surface of the reservoir area. The spatial structure feature which is county-town-village of the Danjiangkou City is obvious, while it is only clustered strongly in the central group and the industrial development at the ’town-village’ level is relatively homogeneous in Yunyang District. After quantitative verification, it is found that population density and terrain slope have a greater impact on the industrial pattern, and there is no strong correlation between the advantages of adjacent water with convenient transportation and the industrial development in this area. Finally, 4 types of township development are divided and corresponding development strategies and suggestions of each are proposed, which takes the township as the basic unit and is baced on the previous analysis and the field research.
