| 摘 要： | 对祁连山排露沟水源流域水分状况进行测定分析,结果表明:流域内水分状况与径流形成潜力具有在空间上的异质性,随坡向、海拔等地形因子而发生规律性变化;流域降水不论坡向、海拔变化均能在满足植被(乔木)生长需要后有结余,水分状况较好.流域高海拔较低海拔水分状况好,形成径流潜力大;同一海拔阴阳坡径流系数没有显著差异,但阴坡森林由于结余的水分多、径流潜力大,对河川径流形成的贡献和调节作用均大于阳坡草地.流域高海拔和阴坡森林面积越大,水分状况越好,产流能力越强;流域阴坡森林对河川径流的调节作用使其面积越大河川径流越稳定. |

| Abstract: | In this paper,the water situation in the Pailugou basin is tested and analyzed. The water situation and runoff production has a spatial differentia and regularly changes with slope direction and altitude.Water in the basin,both on shady or sunny slopes,is enough for plant(arbor forest) to grow,and precipitation is adequate.Water situation in high altitude is better than that in low altitude,with more runoff.There is no significant difference in runoff coefficient between shady slope and sunny slope at the same altitude,but in the forest on shady slope,the contribution and the regulating action of runoff are better than those in the meadow on sunny slope are.It is concluded that the higher the altitude and the larger the forest area of a river basin are,the better the water situation and runoff production are.Moreover,due to the regulation of forest,the larger the forest area on the shady slope is,the more stable the runoff is. |
