| 摘 要： | 利用有关软件，选定径流过程中的显著性因子如上年降水量、汛期月降水量及上月降水量、地温等，分析了黄河源区径流的一般特点、统计特征以及径流与降水、地温的相关性。结果表明：黄河源区汛期降水一径流的相关性较好，年降水量与径流过程的相关系数一般较大，说明地下水补给的作用显著；黄河沿以上地区径流一降水的相关性较差，但与地温的相关性较好，说明下垫面条件对径流调蓄的作用显著。

| Abstract: | The paper selects notable factors in the process of runoff, such as last year's precipitation, monthly precipitation during flood season, last month precipitation and ground temperature and analyzes the general and statistic characteristics of runoff and the relativity of runoff with precipitation and ground temperature of the source area of the Yellow River by using related software. The outcome shows that the relativity of rainfall-runoff in flood season of the source area of the Yellow River is fairly good. The correlation coefficient between annual rainfall and runoff process usually is bigger, showing remarkable function of ground water recharge. The relativity of rainfall-runoff of the region above Huangheyan is worse but the relativity of ground temperature is better, showing notable function of underlying surface on runoff pondage action. |
