| 摘 要： | 农用地分等是在计算农用地气候生产潜力的基础上，乘以一系列的参数，逐级修正得到不同层次的农用地等别的。农用地分等计算过程中要特别注意正确获取作物产量比、自然质量分、土地利用系数和土地经济系数等这些修正系数，以保证各层次分等成果的正确性。

| Abstract: | The method of Farmland Grading is multiplying a series of coefficients to the productive capacity that depend on the climate condition. These coefficients are the equivalent ratio of different grains, the land quality index, the land utility coefficient and the land economy coefficient. At different categories, the farmland grades are obtained by revising step by step, using these coefficients. It is prerequisite to get the correct coefficients for getting the correct results of farmland grading. |
