摘要
水土保持效益指标是一个多目标、多因素的动态灰色控制系统，其时间序列的动态变化可以用灰色控制理论中的灰色模型进行定量分析与预测。根据对鹿马岔小流域产业结构和经济潜力的分析，其预测值是可信的，从而证明了灰色系统理论是小流域水土保持综合治理效益预测实现模型化、定量化的有效方法之一。
The benefit quota of water and soil conservation is a dynamic grey control system with multiple purposes and factors. The dynamic change of time order of quota is analyzed with grey model based on the theory of grey contro'l system. Through analyzing the industrial structure and economic potentiality in Lumacha small drainage basin, the value of the prediction is creditable. It is demonstrated that the theory of grey system is one of the efficient methods for predicting an econornic benefit in a small drainage basin as modelling and quantification.
