农用土地经济定级中两种方法的比较研究——以新疆一四八农场为例

以新疆一四八农场为例，对农用土地经济定级中的模拟作物产量法和综合土地质量法及其结果进行了比较，结果表明：（1）两种方法定级程序基本一致，在地方性区域内的定级结果均较为准确，且一致性较大；（2）模拟作物产量法结果的区域可比性强，但方法复杂；（3）综合土 地质量法方法简便易行，但结果的区域可比性差；（4）两种方法结合，能有效地建立便于比较和纳入全国体系的农用土地经济等级指数。

COMPARISON OF TWO METHODS OF AGROLAND ECONOMIC GRADATION ——A CASE STUDY IN FARM 148 OF XINJIANG AUTONOMOUS REGION

Comparisons between the met hods of simulated crop production and synthetic land quality, for agroland economic gradation, and between their results are made, on the basis of the case study in Farm 148 of Xinjiang Autonomous Region.Results showed that: (1) the procedures of the two methods were almost the same, with results being fairly accurate and highly identical at a local-level; (2) the results of the method of simulated crop production were highly comparable, but its approach was very complicated; (3) the approach of the synthetic land quality method was simple and practicable, whereas the resuts between different areas were less comparable; and (4) with the combination of the two methods, it is easy to set up indexes of agroland economic gradation, comparable with each other and adoptable into the gradation network for the whole country, could be founded.
