Abstract:

In China, a lot of cultivated land is left unused and abandoned. How to control the situation of abandoning land has become the key to ensure food security. By building the "abandonment judgment" model, this paper quantitatively described the types of cultivated land abandonment by calculating the difference between the actual multiple cropping index and the potential multiple cropping index, and use the data of Sichuan in 2006-2018 to describe the spatial and temporal distribution of cultivated land abandonment, and analyzed its influencing factors.The results show that: ① From 2006 to 2013, the degree of cultivated land abandonment in all cities and prefectures showed an expanding trend. After the temporary "singularity effect" in 2014, the degree of cultivated land abandonment continued to increase. ② The perennial wasteland is mainly abandoned in high-altitude areas, while the seasonal wasteland is mainly abandoned in low altitude areas, and there is also perennial wasteland. ③ The cities and prefectures with bad natural conditions are more likely to suffer from perennial cultivated land abandonment, while those with high economic development or urbanization rate are more likely to witness seasonal land abandonment. ④ From the perspective of food security, seasonal abandonment is more threatening than perennial abandonment. Therefore, it is necessary to constantly improve the comprehensive benefits of agricultural production, make grain planting profitable, and solve the key problems of "who will farm", "how to farm", and "what will grow in the field".

摘要:

我国人多地少,现实中却有不少耕地被闲置、撂荒,如何治理撂荒成为当下保障粮食安全的关键问题。通过构建“撂荒判定”模型,利用实际复种指数和潜在复种指数的差异来定量刻画耕地撂荒类型,并以四川2006—2018年面板数据来描述其耕地撂荒时空分布规律、分析其影响因素。研究结果表明:①在时间维度上,2006—2013年,各市州耕地撂荒程度呈扩大趋势,在2014年出现短暂的“奇点效应”之后,耕地撂荒程度继续加大。②在空间维度上,高海拔地区以常年性撂荒为主,低海拔地区以季节性撂荒为主,也存在常年性撂荒。③自然条件越差的市州越容易出现常年性耕地撂荒,而经济发达程度越高或城镇化率越高的市州越容易出现季节性耕地撂荒。④站在粮食安全及造成后果角度来看,季节性撂荒较之常年性撂荒更具威胁性,因而要不断提高农业生产综合效益,让种粮有利可图,解决“谁来种地”“怎样种地”“地里种什么”等关键问题。
