中文摘要:
      随着社会经济的发展和城乡发展快速推进,全球范围内耕地撂荒已成为土地利用和覆被变化的重要趋势之一,深刻改变了农村土地景观,对农村经济可持续发展也产生重要影响。本文利用湟水流域上游36个样本村农户的调查问卷数据,在农户类型划分的基础上,运用logistic多元线性回归模型,从自然、社会等方面分析不同类型农户撂荒耕地的原因,探讨其主要影响因素。结果表明,湟水上游耕地撂荒比较普遍,撂荒农户占比为10.74%,所有农户撂荒面积占总耕地面积比为3.08%,但撂荒农户撂荒面积占撂荒农户耕地面积比高达24.01%,撂荒地主要集中在峡口附近和农牧交错带,平坦地区和距离西宁市较近的地区撂荒较少。耕地撂荒的主要因素为耕地坡陡无法开展机械作业、土地贫瘠和耕地距离远3种;在众多影响因素中自然因素占据主导,其次是农户自身特征因素,最后是社会经济因素。农户会根据耕地特征和自身条件将耕地效益发挥到最大化,同时也会结合现实条件对耕地进行选择性撂荒,故耕地撂荒情况在不同类型农户之间差异明显。不稳定型农户户均撂荒面积最少,稳定型次之,基本型最多。而拥有耕地的数量以及转出面积和退耕面积是不同类型农户撂荒的主要影响因素。同时,研究区内退耕耕地并未完全落实,导致大面积耕地处于荒芜状态。因此,提出需加强耕地保护和补偿、完善土地流转等相关法律制度,大力建设具有农村特色的可持续发展经济模式等建议。
英文摘要:
      With the rapid development of social economy and urban and rural areas, abandoning farmland in the world has become one of the important trends of land use and land cover changes and profoundly changes the rural landscape with a significant impact on the sustainable development of rural economy. Based on a survey data of farmers in 36 sample villages in the upper reaches of Huangshui River basin, this paper adopts a logistic multiple linear regression model to explore the causes of these farmland abandoning behaviors by different types of farmers from the aspects of nature, society and others, and to identify and discuss the influencing factors as well. Results show that the farmland abandoning behaviors in the upper reaches of Huangshui River were common, the proportion of rural households with farmland abandoning behaviors was 10.74%, the total abandoned area accounted for 3.08% of the total farmland area. In addition, the ratio of the abandoned farmland area to the total farmland area of those farmers with abandoning behaviors was 24.01%. The abandoned farmland was mainly concentrated in the vicinity of the throat and the farming-pastoral intersection zone, and there was less abandoned land in the flat areas and the areas close to Xining. The main influencing factors of these abandoning behaviors include land with steep slope not suitable for mechanical operation, land of low soil fertility, and land with long distance from residential areas. Among these influencing factors, natural factors dominate, followed by farmers’ own characteristics, social and economic factors. According to the characteristics of farmland and their own conditions, farmers will maximize the benefits of farmland. At the same time, they will also selectively leave some farmland abandoned according to the actual conditions. Therefore, there is a significant difference between different types of farmers in the situation of abandoned farmland. The unstable rural households had the least abandoned area, followed by the stable rural households and the basic rural households. However, the size of farmland, the transferred area and the converted area are the main influencing factors for different types of rural households. Finally, according to the research results, this paper proposes the following suggestions: to strengthen the protection and compensation of farmland, to improve the relevant legal system of land transfer, and to vigorously build the rural characteristic economy.
