The whole benefit of soil and water conservation is a grey control system with multi purposes and multi-factors. In order to predicte the developing trend of three main benefit targets of grain yield. total living things output and total output value in Ansai Experiment Area of Soil and Water Conservation, three grey model groups are found by a grey theory and programmed in the paper. The model groups are examined to be a GOOD precision. The result predicted by the model groups showed that by 2000 year the grain yield, the total living things output and the total output value will increase respectively 71.7%, 3.14 and about 6 times than 1986 year, and the economical benefit will raise at high speed than the social than and the ecology ones for soil conservation.

水土保持总体效益是一个多目标、多因素的灰色控制系统.本文用灰色理论建立了三个灰色模型群及计算程序,预测了安塞县水土保持实验区三个主要效益指标——粮食产量、总生物量和总产值的增长趋势.该模型群经检验有较好精度.预测结果表明,到2000年,三个指标将分别比1986年增长71.7%、3.14和6倍,水土保持的经济效益比生态效益和社会效益增长快.

The world ecosystem is a grey control system being multi-targets and multi-factors. In this paper, the grey model groups of 10 ecosystems of the world is established by the grey theory and the world ecosystem of 2000 is also predicted.

It is important to the national economic plan to forecast crop yields scientifically and accurately.This paper presents the Grey MODEL group for forecasting crop yields. It was used to forecast the crop yield of one county from 1991to 1995 based on the crop yields of the 1980's. The results indicated the MODEL'S precision was satisfactory.

科学准确地预测粮食产量,对于制定国民经济计划十分重要。目前粮食产量的预测方法很多,本文提出了粮食产量预测的灰色GM(1,1)模型群,并根据某县1981年~1990年的粮食产量资料,对该县1991年~1995年的粮食产量进行了预测。经分析,其预测结果可靠、预测精度比GM(1,1)模型大大提高。
