摘　　要：首先用肯德尔秩次相关检验和斯波曼秩次相关检验对宝鸡市的降水序列及主要河流的年径流序列作了趋势性分析,再用R/S分析法对各序列的长程相关性进行了判别,并计算了各序列的豪斯道夫维数。结果表明:除了冬季降水外,宝鸡市的降水和径流都存在着不同程度的减少趋势;且降水和径流序列都存在着长程相关性,即未来各序列的趋势仍将持续下去;豪斯道夫维数的计算表明各序列的复杂程度是不相同的。The trend of precipitation series and annual runoff series of the main rivers of Baoji City were identified with Mann-kendall and Spearman rank correlation test,and the long-range correlation of all series mentioned above analyzed,then the Hausdorff Dimension of all series calculated in the paper.The results show that the precipitation and runoff of Baoji City have certain decreasing tendency except for winter precipitation;and all series have the long-range correlation which indicated that the tendency would be continuing;and the complex degree of the series were different from each other indicated by the calculated Hausdorff Dimension.
