| 摘 要： | 为探讨亚热带人工林的水文效应,1984～1990年,在江西省分宜县山下林场22年生杉木和马尾松林中,对降雨、径流等进行定点测定,结果表明:试验区林地的年平均径流量为15.648～31.148 mm,年平均径流系数为1.245％～2.537％。降雨量与径流量的较佳回归模型为y=ab。

| Abstract: | In 1984~1990, precipitation, runoff and soil moisture in the 22-year-old plantation of Cunninghamia lanceolata Lamb, and Finns massoniana (Lamb.) Hook, were measured. Some results from 2 small experimental forest watersheds and 2 runoff plots are presented. The ranges of the average annual runoff were 15.648mm to 31.148mm, or 1.245 % to 2.537 % (annual runoff coefficient). Maximum runoff in a time period is about 2.16mm to 24.587mm or 3.07 % to 31.35 % (runoff coefficient). According to the analysis of multi-regression, runoff (y) approximates precipitation (x) in exponential cure regression, its equation is y = abx (a, b be parameter). |
