The Study of Spatial Relationship between Cash Crops Planting and Non-agricultural Activities:A Case Study of Zhecheng County,Henan Province
基于河南柘城县农户数据，发现以县城和乡镇为中心，辣椒种植与非农活动的农户比例随距离呈相反波动，并存在空间均衡区间，对识别农业专业化区域和优化农村空间结构有参考价值。
Both cash crops planting and non-agricultural activities are the important ways to farmers to get money.Based on analyzing the data about pepper planting and non-agricultural activities of farmers in Zhecheng County Henan Province,Found following phenomena: take the county seat as the center,along with the increase of distance,the count rate of farmers who grow pepper is low-high-low.Well,the count rate of farmers who engaged in non-agricultural activities is high-low-high.The spatial equilibrium interval of them is(5—10)km and(25—30)km.However,take the place where the township government is located as the center,along with the increase of distance,the count rate of farmers who grow pepper is low-high-low-high,the count rate of farmers who engaged in non-agricultural activities is high-low-high-low,the spatial equilibrium interval of them is(2—3)km、(5—6)km and(9—10)km.The paper establishes a theoretical model,and gives the possibility of forming above phenomena.To find the characteristics of spatial distribution of specially crop and non-agriculture is very important for identifying agricultural specialized production area,optimizing the spatial structure of rural area,raising the land produce rate.
