【摘要】：耕地是经济社会发展的重要保障,科学保护和合理开发利用耕地资源是全社会的共同责任。由于耕地的重要补充来源是耕地后备资源,对耕地后备资源开展调查与评价工作是国土综合利用的基础,同时其研究结果能够在理论上为耕地总量动态平衡调控决策提供依据,因此对耕地后备资源的调查与评价进行研究是很有意义的。本文以磐石市为调查对象全面、系统的分析了耕地后备资源的内涵、特征及其分类以及耕地后备资源调查的内涵、目的与依据、调查步骤、耕地后备资源的总体分布特征、调查的成果及其应用;不同层次的分析研究了耕地后备资源适宜性评价内涵、评价的目的与意义、评价原则、评价一般过程及适宜性评价指标;阐述了耕地后备资源调查与适宜性评价结果、宜耕耕地后备资源类型、不宜耕土地的主要限制因素分析、耕地后备资源开发复垦对策。通过对磐石市耕地后备资源调查与评价的研究,实现磐石市耕地后备资源合理开发利用,使土地开发复垦效益的达到最大化,建立和完善土地复垦的各项规章制度。耕地后备资源是开展土地整治工作的重要基础,是实现占补平衡的重要保障。通过对耕地后备资源进行清查和摸底,准确掌握耕地后备资源的数量、分布及其质量状况和生态环境条件,是科学开展土地整治活动,合理开发利用耕地后备资源和科学制定耕地保护政策的依据。掌握当前耕地后备资源的基本状况,不仅能够为保护国家粮食安全,同时也能够为耕地后备资源的开发与利用提供一个稳定的基础。
[Abstract]:Cultivated land is an important guarantee of economic and social development. It is the common responsibility of the whole society to scientifically protect and rationally develop and utilize cultivated land resources. As the important supplementary source of cultivated land is cultivated land reserve resources, the investigation and evaluation of cultivated land reserve resources is the basis of comprehensive utilization of land, and the research results can theoretically provide the basis for the dynamic balance adjustment and control decision of the total cultivated land volume. Therefore, it is meaningful to investigate and evaluate the cultivated land reserve resources. This paper takes Panshi city as the investigation object, systematically analyzes the connotation, the characteristic and the classification of the cultivated land reserve resources, the connotation, the purpose and the basis, the investigation procedure, the overall distribution characteristic of the cultivated land reserve resources. The results of the investigation and its application, different levels of analysis and study of arable land reserve resources suitability evaluation connotation, evaluation purpose and significance, evaluation principles, evaluation process and suitability evaluation indicators; The results of investigation and suitability evaluation of cultivated land reserve resources, the types of arable land reserve resources, the analysis of main limiting factors of unsuitable cultivated land, and the countermeasures of cultivated land reserve resources development and reclamation are expounded. Through the investigation and evaluation of the cultivated land reserve resources in Panshi City, the rational exploitation and utilization of the reserve cultivated land resources in Panshi City are realized, the benefits of land development and reclamation are maximized, and various rules and regulations for land reclamation are established and perfected. The reserve resources of cultivated land is the important foundation of land regulation and the important guarantee to realize the balance of occupation and compensation. Through the inventory and mapping of cultivated land reserve resources, it is necessary to accurately grasp the quantity, distribution, quality and ecological environment conditions of cultivated land reserve resources, so as to carry out scientific land regulation activities. Reasonable exploitation and utilization of cultivated land reserve resources and scientific basis for formulating cultivated land protection policies. Mastering the basic situation of cultivated land reserve resources can not only protect the national food security, but also provide a stable basis for the development and utilization of cultivated land reserve resources.
