Abstract:

The revising approach is seldom adopted in agricultural land gradation in China. Although a few studies have been carried out by using the approach, relatively few have examined its rationality and feasibility. The present study may thus represent a pioneer research. Some key techniques for the revising approach were examined in this paper, such as the selection of revising base and factors, and the computation of revising coefficients and of the gradation indexes. One way for the technique was then established, with the inclusion of the natural quality classification index as the revising base, the standardization of all factors influencing values, and with the multiplication of the revising coefficients to obtain the gradation index in quality of agricultural land at last. A comparison between the factor approach and the revising approach in agricultural land gradation was presented. Gaoming, a district in Foshan city, was used as a case for the employment of the approach.
