摘　　要：以农用分等成果为基础,探讨了不同等级耕地保有量预测方法。通过建立耕地利用质量等指数与单位标准量产量之间的数学模型,确定各等别的理论单位标准量产量,将其与区域粮食需求量相对照,构建最优线性规划模型,求出不同等别耕地保有量的最优方案,并以江苏省淮安市为例进行了实证研究。结果表明:该方法测算的耕地保护方案既体现了优先保护优等地的原则,又能保障在经济社会发展的同时遏制耕地数量迅速减少,具有一定的可操作性和实用性,为土地利用总体规划修编中耕地质量保护提供了依据。Based on the achievements of farmland grading, predication method of different grading protection area of cultivated land is advanced. Firstly, the mathematical model between utilization index and the yield of stand- ard food is established, then theoretic standard food yield of different grading is accounted. At last, Based on linear programming model, optimal decision of different grading protection area of cultivated land is advanced. Empirical study of Huaian City in Jiangsu Province also is carried through, and its result indicates： the method can confirm reasonable protection scheme. The paper offers theoretical planning. foundation of cultivated land quality protection in land
