| 摘 要： | 运用灰色系统理论分析渭河林家村站1956-2000年以来径流量的变化趋势，以绝对关联度定量描述径流量与主要影响因素之间的关系，说明引起渭河林家村站径流量变化趋势的原因之一是流域年降水量的变化，而且与年平均气温有一定的关系，为河川径流变化趋势成因分析提供了一种新的思路。

| Abstract: | The authors used grey system theory to analyze the runoff trend of Linjiacun in Weihe river basin from 1956 to 2000, and described the relationship of runoff and main factors by absolutely-related degree. It indicates that runoff variation is partly caused by annual precipitation in the basin, and has relation with annual mean temperature, which provides new thought for the analysis of river runoff change. |
