贵溪市城市周边永久基本农田划定研究

Assignment of Permanent Prime Farmland around Guixi City

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。

Nowadays the contradiction between urban master planning and general land use planning is more and more prominent, land management is facing serious challenges, it will cause certain influence on the stability of prime farmland. Based on two-plan integration, taking Guixi City, Jiangxi Province as the research area, the approach to the assignment of the permanent prime farmland around the city was explored. On the basis of two-plan integration, urban development boundary and cultivated land comprehensive quality, permanent prime farmland was demarcated by means of selecting farmland natural quality, cultivated land continuity, patch shape index, the distance from cultivated land to rural roads and the distance from cultivated land to countryside residential area as the indicators the comprehensive evaluation index system of permanent prime farmland was established. Using the index method the scores of prime farmland were determined.The priority for cultivated land to be included in the prime farmland was determind according to the index scores of the cultivated land quality, and following the principle of maximum similarity the prime farmland was divided into prior planning type, suitable addition type, main regulation type, and removal quitting type, and the prime farmland was designated.The farmland of good quality around the city, along the road which had not been designated should be designated as the prime farmland, meetin the standard, the quantity of prime farmland assured, the quality improved and layout optimized.
