经济作物种植与非农生产活动空间关系探究——以河南省柘城县为例

The Study of Spatial Relationship between Cash Crops Planting and Non-agricultural Activities:A Case Study of Zhecheng County,Henan Province

经济作物种植和非农生产活动均为农户用于获取经济收入的重要途径。通过对河南省柘城县辣椒种植业及非农生产活动的调查分析,发现经济作物种植与非农生产活动空间分布呈现一定的对应关系:以县城为中心,随着距离的增加,二者分别呈现"低—高—低"和"高—低—高"的空间分布特征;以各自所属乡镇行政中心所在地为中心,随着距离的增加,二者分别呈现"低—高—低—高"和"高—低—高—低"的空间分布特征。建立理论模型,并给出了形成以上现象的可能性原因。找出特定农作物与非农生产活动空间分布特征,对鉴别农业专业化生产区域、优化农区空间结构、提高土地产出率具有重要意义。

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, ~ilong 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.
