摘要
清水河克尔古提水文站自1993年后为汛期驻测站,目前在进行清水河水资源评价和水文分析计算时,缺少年径流量值各种插补方法的比较和精度的评定。分析了该河的降水、径流和枯水等水文特性,通过三种方法进行年径流量值的插补,并运用1991年--1993年实测月、年径流资料来检验各种方法插补值的精度。通过分析,枯水退水曲线法与线性相关关系和历年均值代替法相比;插补值比较准确。因此克尔古提水文站缺测年份的月、年径流资料可用该法进行插补,从而能够更加准确的了解清水河水资源量和分配规律,为下游工农业生产规划提供年来水量依据。
The Keeguti Hydological Station in Qingshui River has been the fix observatory since year 1993. The present situation in the water resources evaluation in Qingshui River and the hydrology analysis calculation is lack of investigation data for the eomparation among the different interpolation methods and precise evaluations. This paper analyzed the hydrological feature include precipitation, runoff and low water of Qingshui River, and interpolates the annual runoff by three different methods and test the accuracy of various methods of interpolation values using the ac- tual month, annual runoff data from 1991 to 1993. The results of the paper showed that the Low-flow back water curve method gives more precise interpolation value than the linear relationship method and the multi-year average instead method. Therefore, the missing month, annual runoff data of the Keeguti Hydological Station could be interpolated by this interpolation method, allowing a more accurate understanding of water quantity and the distribution of water resourees. It serves as a water information for downstream industrial and agricultural production planning.
