摘　　要：明确非粮作物空间分布格局、演化机制及包括土壤质地类型在内的影响因素,不仅是对人地关系的解读,也可为限制“非粮化”的盲目扩张提供决策依据。论文以河南省宁陵县14个乡镇339个样本村为例,以时间为轴线,采用ArcGIS空间分析法对县域内非粮作物空间分布格局及其形成过程进行分析发现,非粮作物始终在土壤质地粗、养分含量低的“西北—东南”方向的带状区域内演变。采用多元线性逐步回归分析法,对这一现象的影响因素进行分析发现,土壤因素决定了非粮作物“带状”分布的初始格局,“邻里效应”逐步扩展了该带状区域,区位交通条件及非农产业的发展使得这一格局得以强化;虽然地方政府早期的非粮激励政策扩展了“带状”区域,但之后的非粮整治举措有望收紧这一趋势。研究认为,土壤质地类型对农业生产结构的影响不容忽视,它不仅发挥着基底的作用,而且始终与其他因素产生交互作用,时刻影响“非粮”作物格局。因此,“非粮化”治理工作需要重视包括土壤质地类型在内的更多自然地理要素。Clarifying the spatial distribution characteristics of non-grain crops and the formation mechanism of the pattern is important for understanding the human-land relationship and is a basis for the implementation of the preventing"non-grain transition"of cultivated land policy.In this study,339 sample villages were chosen in 14 townships of Ningling County,Henan Province as an example.The spatial distribution of non-grain crops and the formation process in the county over time were examined in detail.The survey showed that non-grain crops first appeared in the north of the county,and then gradually spread in a strip in the northwest-southeast direction.Villages specialized in non-grain crop production are also concentrated in this area.Factors that affect the spatial distribution of non-grain crops were measured using the stepwise linear multi-variation regression model.The results show that the non-grain crop planting rate was higher in villages with lower soil nutrient contents and heavier desertification,and poorer social capital."Neighborhood effect"gradually led to the expansion of the non-grain crop planting area;and improved traffic conditions and the development of non-agricultural industries strengthened this pattern.Although the local governments'earlier non-grain incentive policies expanded the nongrain crop planting area,subsequent countermeasures are expected to reverse this trend.We conclude that the influence of soil texture type on agricultural production structure is a vital factor that needs consideration.Soil plays the role of the natural basis for crop production and it interacts with other factors of farmers'production decisions and affects the pattern of non-grain crop planting.Hence,physical and geographical factors,including soil texture type must be considered in order to prevent the non-grain transition of cultivated land.
