选取该河流域巴仑台气象站的降水、蒸发资料和黄水沟水文站的降水、蒸发资料,运用数理统计的方法对流域内时空变化特征进行分析,结果表明,黄水沟流域降水、蒸发年内分配不均,但年际变化不大;流域内随海拔高度增高降水量增大,随海拔高度降低蒸发量增大,降水、蒸发与流域高度关系密切。
The data of precipitation and evaporation of the Baluntii meteorological station in the river basin and the precipitation and evaporation data of Huangshuigou hydrological station are selected to analyze the characteristics of spatio-temporal variations in the basin using mathematical statistics. The results show that precipitation and evaporation During the year, the distribution was not uniform, but the change was not significant in the interannual period. The precipitation increased with the altitude above sea level, and the evaporation increased with decreasing altitude. The precipitation and evaporation were closely related to the basin height.
