北庄河小流域
经过几年综合治理
水土流失明显减少
生态环境和社会面貌有了巨大变化
1981—1985年纯收入分别为18.38、20.10、31.75、44.67和59.67万元。用灰色系统理论的GM(1
1)模型分析
预测1986—1990年的总经济收入分别为82.12、114.79、160.46、224.31和313.56万元。若无灾害性天气或其他意外盈亏
这个预测是可靠的
效益是令人满意的。
Having harnessed comprehensively for years
Beizhuanghe watershed has changed greatly in biological environment and social features
soil loss and erosion have reduced obviously. The total pure incomes (TPI) are 183
800、201
000、317,500、 446
700 and 596
700 yuan respectively from 1981 to 1985. According to the GM(1,1)with grey system theory
it is predicted that the TPI during 1986-1990 will be 0.8212、1.1479、1
6046、2.2431
and 3.1356 million yuan respectively. The prediction results would be reliable and satisfying if no disastrous weather or unforseen inoutcome arised.
