摘要
对西沟水库流域不同地类上的积雪厚度、密度和融雪速度进行了比较 ,分析了融雪速度与各种自然因子之间的关系 ,经主成分、多元回归、逐步回归分析 ,得出了融雪速度与各种自然因子之间存在着高度显著的回归关系。
The accumulating snow depth, density and melting speed in different kinds of land in Xigou watershed were compared and the relationship between snow-melting speed and all kinds of natural factor was analyzed. The analyses of principle component, multivariate regression and stepwise regression, show regression relationship between snow-melting speed and all kinds of natural factor. The regression relationship has some directive significance for the research of snow-melting volume and the protection in spring flood.
