【摘要】：现如今城市总体规划和土地利用总体规划之间的矛盾越来越突出,用地管理面临严峻挑战,这将会对基本农田的稳定性造成一定的影响。通过立足于两规合一,以江西省贵溪市为研究区域,拟探索城市周边永久基本农田的划定方法。在考虑两规、城市开发边界和耕地综合质量的基础上进行永久基本农田划定,从自然质量条件、空间形态和区位条件三方面选取农用地自然质量等别、耕地连片性、斑块形状指数、耕地到农村道路的距离、耕地到农村居民点的距离等5个指标,建立耕地入选永久基本农田的综合评价指标体系,采用指数法对耕地入选基本农田进行分值确定,根据耕地质量综合指数分值来判断耕地入选基本农田的优先程度,同时遵循最大相似性原理划分为优先划入型、适宜调入型、重点调控型和缩减退出型4种类型耕地,从而确定划入基本农田的耕地。将城市周边和道路沿线应划入却尚未划入的优质耕地划入基本农田,达到上级下达指标,做到基本农田保护数量不减少、质量有提高且布局更优化。
[Abstract]:Nowadays, the contradiction between the urban master plan and the land use master plan is more and more prominent, and the land management is facing severe challenges, which will have a certain impact on the stability of the basic farmland. Taking Guixi City, Jiangxi Province as the research area, this paper intends to explore the method of delineating permanent basic farmland around the city. On the basis of the consideration of two rules, the urban development boundary and the comprehensive quality of cultivated land, the permanent basic farmland is delimited from the natural quality conditions. In three aspects of spatial form and location condition, five indexes, such as natural quality of agricultural land, continuous farmland, patch shape index, distance from cultivated land to rural road and distance from cultivated land to rural residential area, are selected. A comprehensive evaluation index system was established for the selection of cultivated land into permanent basic farmland. The index method was used to determine the score of farmland selected into basic farmland, and the priority degree of farmland selection was judged according to the comprehensive index value of cultivated land quality. At the same time, according to the principle of maximum similarity, there are four types of cultivated land: priority input, suitable for transfer, key control and reduction and withdrawal. In order to determine the arable land that should be classified into basic farmland. The high quality cultivated land that should be classified around the city and along the road that has not yet been classified into the basic farmland, so that the number of basic farmland protection will not be reduced in order to reach the targets issued by the higher authorities, The quality is improved and the layout is optimized.
