耕地细碎化促进了耕地“非粮化”吗 ——基于福建丘陵山区农户的微观调查

研究目的:基于福建省丘陵山区的农户调研数据,探讨耕地细碎化对耕地“非粮化”的影响。研究方法:有序Probit模型和Tobit模型。研究结果:(1)耕地细碎化促进了耕地“非粮化”的种植意愿和种植规模;(2)由于粮食的生活保障作用,当耕地细碎化程度增加时,农户同时种植粮食作物和经济作物的概率要高于仅种植经济作物的概率;(3)户主年龄、土壤肥力、承包地梯田占比、耕地分散程度、机械化程度、村庄到县城的距离也是影响耕地“非粮化”种植意愿和规模的重要因素。研究结论:耕地细碎化促进了耕地“非粮化”,应该在严格把控耕地“非粮化”底线的基础上,明确耕地利用优先序,通过缓解耕地细碎化,优化细碎化耕种方式的手段促进粮食生产,从而达到稳固粮食安全的目的。

Does Cultivated Land Fragmentation Promote“Non-grain”Utilization of Cultivated Land:Based on a Micro Survey of Farmers in the Hilly and Mountainous Areas of Fujian

The purpose of this study is to analyze the impact of farmland fragmentation on the“non-grain”planting structure of farmers based on the survey data in the hilly and mountainous areas of Fujian Province.The methods of ordered Probit model and Tobit model were employed.The results show that:1)cultivated land fragmentation has a significant positive effect on the“non-grain”planting willingness and scale;2)due to the role of food security,when the degree of cultivated land fragmentation increases,the probability of farmers planting food crops and cash crops at the same time is higher than the probability of planting only cash crops;3)the age of the head of rural household,soil fertility,the proportion of terrace,the degree of cultivated land dispersion,the degree of mechanization,and the distance from the village to the county are also important factors that affect“non-grain”planting willingness and scale.In conclusion,cultivated land fragmentation promotes the“non-grain”utilization of cultivated land.Based on the strict the bottom-line control of“non-grain”utilization of cultivated land,the priority of cultivated land use should be clarified,and the means of reducing the cultivated land fragmentation and optimizing the fragmented cultivation should be explored to promote food production,so as to achieve the purpose of stabilizing food security.
