农用地分等成果在土地利用总体规划中的应用

不同层次的农用地分等成果有着不同的应用方向。文章以土地利用总体规划为导向，以农用地利用等别与自然等别的高低延伸顺序与耕地最低需求量相结合，确定出基本农田保护的数量；以基本农田数量的105％～110％为基准，将县级利用等别图与自然等别图重叠的区域划定为基本农田保护区；交叉运用分等的土壤肥力图、气候生产潜力指数曲线图来选择作物适宜生长区和改良土地用养结构；以分等因素图作为限制因子的选择标准来划分土地限制类别区。

The Application of Farmland Classification Productions in Overall Planning of Farmland

The productions of multi-level farmland classification can be used in different aspects. Oriented by the overall planning of land, the quantity of basic farmland can be figured out based on the sequence of practical levels and the natural levels of farmlands and the minimum demand of farmlands. Presumed the farmland quantity multiply 105-110 percents to be the cardinal number, the superposition area of county-grade practical level plat and the natural level plat is supposed to be the protected basic farm. Classified soil fertility plat and connotative climate production index curve are used together to select the area in which crops can grow well and the structure of land using and maintaining can improved. Presumed the class-factor-plat to be standard, farm restrictive areas can be marked off.
