| 摘 要： | 据2001年秋季人工增雨资料，结合历年秋季降水资料，从秋雨春用、影响地下水位涵养、青海湖水量盈亏等方面分析了秋季人工增雨的综合效益；并着重分析了秋季降水与环湖地区土壤水分贮量以及第二年春季环湖天然草场土壤墒情、牧草返青时间、生长状况及产量的关系。分析表明：秋季降水越多，环湖区土壤水分贮存量越多，翌年土壤墒情越好、牧草返青越早且牧草产量越高。

| Abstract: | Based on the rainfall data in autumn, an analysis of synthesis profit, such as autumn rainfall utilized in spring, the change of soil moisture, water storage variation in Qinghai Lake and so on, of the artificial precipitation is made. It shows that if the rainfall increased in the autumn, the storage of the soil water was higher next spring, moreover the better the soil moisture, and the earlier the regreening, and the higher herbage yield of the natural grassland. |
