【摘要】：耕地是人类生存和发展的重要物质基础,是农业生产的核心资源,是粮食安全和农业可持续发展的重要保障。我国面临人均耕地少,耕地质量差,耕地退化严重,后备耕地资源严重不足,耕地减少态势加剧等严重问题。随着我国经济、社会以及城市化的迅速发展,我国农业走过了一条高投入、高产出、高速度和高资源环境代价的道路。城市化与基础设施建设对优质耕地的侵占越来越多,水土流失不断扩大,耕地地力逐渐下降,土壤污染面积大范围扩大,农户耕地质量保护不足等问题日益凸显,因此,保障耕地资源对于满足人类的生存和发展尤为关键。耕地资源问题研究不能再仅仅是停留在数量问题研究层面上,更应该向质量问题研究上升级。为了实现这一转变并提出合理的耕地质量问题研究建议,本研究选择吉林省粮食主产区作为研究区。吉林省粮食主产区是我国重要的商品粮基地。本研究在总结国内外耕地质量问题研究的基础上,分析了吉林省粮食主产区耕地质量的现状及耕地质量下降的原因。通过调查吉林省粮食主产区的具体情况,设计调查问卷的统计变量,利用二项式Logistic回归模型对调查问卷数据进行分析,从而进一步揭示农户耕地质量保护行为的影响因素,为耕地质量保护机制建设提供决策参考。分析结果表明:吉林省粮食主产区耕地质量存在水土流失扩大,耕地地力下降,土壤污染严重,地下水位下降,减优增劣现象突出的现状。耕地质量下降的制约因素为技术因素、制度因素、管理因素、投入因素。农户耕地质量保护行为的影响因素为被调查的年龄、受教育程度、对耕地质量重要性的认知、对耕地质量的关注程度、家庭总人数、务农收入占家庭总收入比重、耕地细碎化程度、耕地质量保护的宣传状况、政府对耕地质量的投入。针对上述分析结果,本研究提出吉林省粮食主产区耕地质量保护机制建设,包括建设农户耕地质量保护激励机制、政府耕地质量保护投入机制、耕地质量保护管理机制、耕地质量保护监督机制等方面。
[Abstract]:Cultivated land is an important material basis for human survival and development, a core resource for agricultural production, and an important guarantee for food security and agricultural sustainable development. China is faced with serious problems such as less cultivated land per capita, poor quality of cultivated land, serious degradation of cultivated land, serious shortage of reserve cultivated land resources, worsening situation of cultivated land reduction and so on. With the rapid development of our economy, society and urbanization, our agriculture has gone through a path of high input, high output, high speed and high cost of resources and environment. Urbanization and infrastructure construction occupy more and more high-quality cultivated land, soil erosion is expanding, cultivated land fertility is decreasing gradually, the area of soil pollution is expanding, and the quality protection of farmers' cultivated land is becoming more and more prominent. The protection of cultivated land resources is particularly critical for the survival and development of human beings. The study of cultivated land resource problem should not only stay on the level of quantity problem, but also upgrade to the research of quality problem. In order to realize this change and put forward some reasonable suggestions for the study of cultivated land quality, the main grain production area of Jilin Province was chosen as the research area in this study. Jilin Province grain main production area is our country important commodity grain base. On the basis of summing up the research of cultivated land quality at home and abroad, the present situation of cultivated land quality in main grain producing areas of Jilin Province and the reasons for the decline of cultivated land quality were analyzed. By investigating the specific situation of grain production areas in Jilin Province, designing the statistical variables of the questionnaire and analyzing the questionnaire data by using the binomial logistic regression model, this paper further reveals the influencing factors of farmland quality protection behavior of farmers. To provide decision-making reference for the construction of cultivated land quality protection mechanism. The results show that the quality of cultivated land in the main grain-producing areas of Jilin Province is characterized by the expansion of soil and water loss, the decrease of cultivated land fertility, the serious soil pollution, the decrease of groundwater level, and the prominent phenomenon of decreasing optimization and increasing deterioration. The factors restricting the decline of cultivated land quality are technical factor, system factor, management factor and input factor. The influencing factors of farmers' cultivated land quality protection behavior were age, education level, the importance of cultivated land quality, the degree of attention to cultivated land quality, the total number of households, the proportion of farm income to total household income. Degree of fineness of cultivated land, propaganda of cultivated land quality protection, government investment in cultivated land quality. In view of the above analysis results, this study puts forward the construction of cultivated land quality protection mechanism in the main grain producing areas of Jilin Province, including the construction of incentive mechanism of farmland quality protection for farmers, the input mechanism of government cultivated land quality protection, and the management mechanism of cultivated land quality protection. Cultivated land quality protection and supervision mechanism.
