【摘要】：土地是人类社会赖以生存和发展的物质基础,耕地作为土地资源的核心与精华,是农业生产过程中不可或缺的生产资料。有效保护耕地和提高耕地质量对国民经济健康稳定发展具有十分重要的意义。因此,开展耕地资源数量调查和质量评价,实时监测耕地数量及质量变化,以找出相应问题并提出具体解决措施,从而不断改进耕地管理政策,保障耕地资源可持续管理与利用是当前耕地保护面临的一项紧迫任务。本文在综述国内外耕地分等定级发展的基础上,归纳耕地质量等别评定的方法,进而探讨适用于区域耕地质量等别评定的思路和方法,并应用于浙江省嘉兴市南湖区的实践研究中,以期对区域耕地质量等别评定的理论研究和实践工作有所借鉴。通过浙江省嘉兴市南湖区耕地质量等别评定的实例研究,实现了耕地质量的年度监测功能,有利于逐步建立耕地质量等别定期调查评价制度,实现耕地保护工作由数量管理为主向数量与质量并重的转变,为今后基本农田划定、占补平衡以及新一轮土地利用总体规划等工作的开展奠定了基础,切实提升了区域耕地资源保障能力和国土资源管理水平。
[Abstract]:Land is the material foundation on which human society depends for survival and development. As the core and essence of land resources, cultivated land is an indispensable means of production in the course of agricultural production. Effective protection of cultivated land and improvement of cultivated land quality are of great significance to the healthy and stable development of national economy. Therefore, we should carry out the quantity investigation and quality evaluation of cultivated land resources, monitor the change of cultivated land quantity and quality in real time, find out the corresponding problems and put forward concrete solutions, so as to continuously improve the policy of cultivated land management. It is an urgent task to ensure the sustainable management and utilization of cultivated land resources. On the basis of summing up the development of cultivated land grading at home and abroad, this paper sums up the methods of farmland quality evaluation, and then discusses the ideas and methods suitable for regional cultivated land quality evaluation. It is applied to the practical research in the Nanhu District of Jiaxing City, Zhejiang Province, in order to draw lessons from the theoretical research and practical work of regional cultivated land quality assessment. The annual monitoring function of cultivated land quality is realized through the case study of cultivated land quality in Nanhu District of Jiaxing City, Zhejiang Province, which is conducive to the gradual establishment of regular investigation and evaluation system for cultivated land quality. The transformation of cultivated land protection from quantity management to both quantity and quality has laid a foundation for the future basic farmland delineation, balance of occupation and compensation, and a new round of overall planning for land use. It has effectively improved the ability of ensuring regional cultivated land resources and the level of land and resources management.
