【摘要】：“十一五”规划纲要求,截止到2010年年底,全国耕地面积不低于18亿亩。2013年末,第二次全国土地调查数据显示,我国耕地总面积已达13538.5万hm2,比第一次全国土地调查数据多近1358.7万hm2,但实际上,出现了“面积未增、数据增”的现象。2014年4月,国土资源部办公厅颁布了《关于开展全国耕地后备资源调查评价工作的通知》,由此以全国第二次土地调查成果为基础的耕地后备资源调查评价工作全面开展。此次调查,统计全国各类耕地后备资源数量和分布等基本情况,运用最新汇总的评价数据,建立耕地后备资源调查评价数据库,结合社会、经济、环境影响,进行耕地后备资源适宜性评价,分析耕地后备资源在不同土地利用方式下,开发利用的可行性及时序性。然而,就此现实与政策大前提,我国对于耕地后备资源评价体系和方法还没有统一标准。随着高新技术与研究理论和经验不断丰富,要求应根据耕地后备资源的特点,从利用高新技术；创新理论支撑；改进评价体系；研究计算模型等方面进一步丰富耕地后备资源研究。本文的撰述,恰逢全国范围开展耕地后备资源调查工作契机。从对耕地后备资源评价工作的背景、国内外研究现状入手；明确研究目的意义；界定相关概念；以内蒙古自治区通辽市开鲁县为案例研究区进行调查；以对耕地后备资源宜耕潜力选取的各个指标分析为基础,建立耕地后备资源宜耕性潜力评价的指标体系；以ARCGIS的空间叠加与成图等功能为工具,运用潜力等级测算的定量方法为研究该县耕地后备资源宜耕性的潜力等级和类型,并进一步分析不同的潜力等级在空间布局的特征。最终,根据宜耕性潜力等级和结构布局,对该县耕地后备资源开发提出合理性建议。本文的理论意义在于研究体系的论述,可以丰富耕地后备资源开发利用在具体方法、研究思路、选择指标等方面的理论研究；实践意义在于针对开鲁县的研究成果,对研究区耕地后备资源具有较强的适用性与指导性,为开鲁县耕地后备资源开发利用提供了参考建议。
[Abstract]:According to the "Eleventh Five-Year Plan", by the end of 2010, the area of cultivated land in the whole country will not be less than 1.8 billion mu. The data of the second national land survey show that The total area of cultivated land in China has reached 135.385 million hm2, nearly 13.587 million hm2, more than the first national land survey data, but in fact, the phenomenon of "no increase in area, increase in data" appears. The General Office of the Ministry of Land and Resources has promulgated the notice on carrying out the investigation and evaluation of the national cultivated land reserve resources, which is based on the results of the second national land survey. In this survey, the basic situation of the number and distribution of all kinds of arable land reserve resources is counted and the database of investigation and evaluation of arable land reserve resources is established using the latest aggregate evaluation data, which combines social, economic, and environmental impacts. The suitability evaluation of cultivated land reserve resources was carried out, and the feasibility and timing of cultivated land reserve resources development and utilization under different land use modes were analyzed. However, there is no unified standard for the evaluation system and methods of cultivated land reserve resources in China. With the rich theory and experience of high-tech and research, it is necessary to improve the evaluation system according to the characteristics of cultivated land reserve resources from the use of high and new technology, innovation theory support, improvement of evaluation system. The study of cultivated land reserve resources is further enriched in the research of calculation model and so on. The compilation of this article coincides with the opportunity to carry out the investigation of cultivated land reserve resources nationwide. From the background of the evaluation of cultivated land reserve resources, domestic and foreign research status quo; clear research purpose significance; define the relevant concepts; take Kailu County, Tongliao City, Inner Mongolia Autonomous region as a case study area; Based on the analysis of the indexes of selecting suitable tillage potential of cultivated land reserve resources, the evaluation index system of arable land reserve resources suitable tillage potential is established, and the functions of spatial superposition and mapping of ARCGIS are used as tools. The quantitative method of potential grade calculation is used to study the potential grade and type of arable land reserve resources in this county, and to analyze the characteristics of different potential grades in spatial distribution. Finally, according to the potential grade and structure layout of arable land, reasonable suggestions are put forward for the development of cultivated land reserve resources in this county. The theoretical significance of this paper lies in the discussion of the research system, which can enrich the theoretical research on the development and utilization of cultivated land reserve resources in terms of specific methods, research ideas, selection of indicators, etc. The practical significance lies in the research results of Kailu County. It has strong applicability and guidance to cultivated land reserve resources in the study area, and provides reference suggestions for the development and utilization of cultivated land reserve resources in Kailu County.
