[Abstract]:According to the carrying capacity of resources and environment, the current development density and development potential, the future population distribution, economic distribution, land use and urbanization pattern of our country should be considered as a whole. The land and space are divided into four main functional areas, namely, optimized development, key development, restricted development and prohibition of development. "[1] the main functional regionalization will guide and constrain the future population distribution and economic distribution of our country," he said. The overall plan of land use and urbanization will have a profound and substantial impact on the order of space development in China. This paper mainly studies the guiding role of the evaluation results of available land resources in the process of main function regionalization. The quantity and quality distribution of available land resources reflect the potential of land utilization and the carrying capacity of environment in this area. The evaluation results are regarded as a guiding factor in the division of the main functional areas of Gansu Province in order to achieve the purpose of optimal land use. The main research results of this paper are as follows:. The total area of land resources available in Longdong Loess Plateau is 423651.448hm2.It is mainly distributed in Huan County, Qingcheng County, Zhenyuan County and Lingtai County of Pingliang City. The area of land resources available in this district is 1125231.431hm2.It accounts for 15.33hm2.It is mainly distributed in Jingyuan County, Jingtai County, Huining County, Yongdeng County and Gaolan County. The usable land resources area in Longnan Mountain area is 374959.430hm2, which is relatively small compared with the total amount of the whole province. It is mainly distributed in Qinzhou District, Maiji District, Qinan County and Cheng County of Longnan City in Tianshui City. The area of available land resources in Gannan Plateau area is 16943.080 hm2.It accounts for 0.29% of the whole province. The total amount is the least. It is mainly distributed in Luqu County, Maqu County and Xiahe County. The area of available land resources in Hexi Corridor area is 1943 / 627hm2.The total amount is the largest, mainly distributed in Yumen, Suzhou, Subei and Gaotai counties of Jiuquan. The total amount of available land resources per capita in Hexi area is the largest, which is 0.403hm2 / person. According to the available land resources abundance rating, the available land resources of 87 counties and districts in Gansu Province are divided into extremely rich, rich, rich, lacking and lacking five grades. (2) the guiding role of the evaluation results. The region with abundant land resources can be determined as the key development area, and the supply of construction land can be expanded appropriately and pertinently. Generally, the rich area strictly controls the increment of construction land, Invigorate the stock. Strengthen the propaganda and education to the area of land resources deficiency and strengthen the consciousness of land protection. (3) Land use measures in different functional areas. Strict land use control is imposed on areas prohibited from development, and ecological land use change is strictly prohibited; land use control in development areas is strengthened to control the conversion of land use. Accelerate the establishment of ecological compensation mechanism [3], impose appropriate resource tax on the land developed and utilized, and promote the formation of standardized financial transfer payments in order to achieve harmony between man and land; the key development areas should appropriately expand the supply of construction land, Actively carrying out land development, consolidation, reclamation, strengthening the protection of cultivated land, and strengthening the management of construction land [4]; to optimize the development and utilization of land in development zones, it is necessary to intensively economize the use of land, and scientifically formulate and implement land use planning, Strictly implement the quota standard of construction projects, control the incremental land use, vigorously promote the internal tapping of potential, activate the stock land, give full play to the role of the market mechanism in the basic allocation of land resources [5], open up sources of income and cut down expenditure, and allocate all kinds of land reasonably.
