内蒙古梯田水土保持效益分摊系数分析

BENEFIT-SHARED COEFFCIENT OF WATER CONSERVATION FOR TERRACED LAND IN INNER MONGOLIA

采用产量分解的方法，运用灰色系统中的GM（1．1）模型，对梯田的趋势产量和水保产量进行灰色拼合，确定了我区水平梯田、坡式梯田的水保产量及其效益分摊系数。

The paper employed resolving yield method and GM (1. 1 ) model to irnitate potentialyield and water - conservation yield of terraced lands, having determined the water-conservation yields and thire benefit-shared coefficients for terraced land and ridged slopeland in Inner Mongolia.
