【摘要】：土地资源是人类赖以生存的生产资料。现阶段我国人多地少，耕地后备资源严重不足。随着社会和经济的高速发展，各项建设对土地的需求量增加，土地资源变得越发珍贵。因此，土地整治成为我国实现耕地总量动态平衡，促进国民社会经济协调发展、可持续发展的主要途径。 本文以泸定县为例。在ARCGIS软件的支持下，运用样区调查研究的方法对泸定县的农用地整治潜力进行测算研究。首先对泸定县土地利用现状进行调查统计，将泸定县耕地分为平耕地和坡耕地，分类型选取样区统计耕地面积，农村道路、沟渠、田坎面积，计算沟路坎系数。并用理想地块法来制定泸定县农用地地整治标准。测算出泸定县各乡镇农用地整治潜力。最后对农用地潜力级别分等。 研究通过与GIS技术手段结合对数据进行分析可以得到更科学、直观的结果，，是土地资源研究的先进手段之一。 本文研究结果表明，泸定县农用地有很大的整治潜力，泸定县应进一步加强土地管理，发掘土地整治潜力，加强科学技术在土地整治方式中的应用。通过土地整治促进区域土地利用的经济、社会、环境三效益的协调、统一，并随着社会经济的发展，三种效益不断提高，形成良性循环发展，即在社会经济发展的各个阶段上，土地的利用都是合理可持续的。
[Abstract]:Land resources are the means of production on which human beings live. At this stage, our country has more people and less land, and the cultivated land reserve resources are seriously insufficient. With the rapid development of society and economy, land resources become more and more precious. Therefore, land regulation has become the main way to realize the dynamic balance of cultivated land amount, promote the coordinated development of national society and economy, and sustainable development. This paper takes Luding County as an example. With the support of ARCGIS software, the potential of agricultural land regulation in Luding County was calculated and studied by using the method of sample area investigation and research. Firstly, the present situation of land use in Luding County is investigated and counted. The cultivated land in Luding County is divided into plain cultivated land and sloping cultivated land. The area of cultivated land, rural roads, ditches and canals are selected to calculate the coefficient of gully and ridge. And the ideal plot method to establish the Luding County agricultural land regulation standards. The potential of agricultural land renovation in Luding County was calculated. Finally, the potential of agricultural land grading. The research can get more scientific and intuitive results by combining with GIS technology. It is one of the advanced methods of land resources research. The results of this paper show that the agricultural land in Luding County has great potential for land regulation, and the land management in Luding County should be further strengthened, the potential of land regulation should be excavated, and the application of science and technology in the mode of land regulation should be strengthened. To promote the coordination and unification of the economic, social and environmental benefits of regional land use through land regulation, and with the development of social economy, the three benefits are continuously improved, forming a virtuous circle of development, that is, in each stage of social and economic development, Land use is reasonable and sustainable.
