| 摘 要： | 选取宝鸡峡灌区降水、蒸发及径流资料,应用变差系数,累积距平法和Kendall秩次相关检验等分析方法分析各要素的变化趋势,绘制灌区气象要素空间分异性等值线图,并探究灌区主要灌溉水源历史演变过程及规律。结果表明:灌区降水,蒸发,林家村水文站年径流量年内分配都不均匀。年蒸发量有增加趋势,但趋势不显著;年降水量表现为减少的趋势;林家村水文站的年径流量减少十分显著。

| Abstract: | Selecting the data of precipitation,evaporation and runoff in Baojixia Irrigation District,the variety characteristics of hydrologic factors were analyzed with coefficient of variation,and by using the method of accumulative variance and Kendall rank correlation test.Contour map of spatial variability was given.And the historical evolution and rule of the main irrigation water were explored.The results show that annual precipitation,evaporation,runoff at the Linjiacun station is of uneven distribution durin... |
