摘要: 学术界对难以稳定利用的耕地后续利用可能的影响及如何优化利用尚不完全清晰。本文从粮食安全、农民收入和生态影响三维度构建了不稳定耕地后续利用影响量化评价体系,并以甘肃省景泰县为例评估了不稳定耕地后续利用影响。评估结果显示,景泰县不稳定耕地如果退耕会造成地区粮食总产量下降1.29%,农民纯收入下降10.22%,但是继续维持耕种则会带来严重的生态问题。在粮食安全、农民收入和生态影响的前提下,提出了景泰县不稳定耕地后续优化利用建议。在个案经验基础上,区分不稳定耕地不同利用状况,提出了“维持耕种用途”、“工程改造”和“逐步退耕”三种后续处置方式,归纳出一套适用于县级尺度的不稳定耕地后续优化利用分析框架,可为不稳定耕地后续利用管理等实际工作提供参考。

Abstract: The existing studies have not yet paid enough attention to the potential impact of the unstable farmland utilization and how to optimize utilization of the unstable farmland. This paper developed a primary impact assessment system of unstable farmland utilization from the triple dimensions of food safety, famers' income and ecological safety, and employed the impact assessment system to analyze the impact of unstable farmland utilization in Jingtai County of Gansu province. The results show that the grain output will decrease by 1.29% and the net income of farmers will fall by 10.22% if all unstable farmland is not used for agricultural production in Jingtai County. However, remaining agricultural production will also lead to serious ecological problems in Jingtai County. Under trade-offs between food safety, famers' income and ecological safety, this paper put forward the suggestions of optimized utilization of unstable farmland in Jingtai County. Based on the case experience, this paper also distinguished the different utilization status of unstable farmland, and proposed three subsequent management measures including remaining farming, engineering reconstruction and farmland conversion. Finally, this paper generalized an analytical framework of unstable farmland management at county-level in China, which provided an policy implication for future unstable farmland utilization.
