摘要
利用长系列雨量站资料,采用数理统计法分析年降水量的多年变化,并对1956～2000,1956～1979,1971～2000,1980～2000年等短系列年降水量的系列代表性作出分析评价,为合理选用水文系列提供依据;对新疆水资源调查评价和水资源综合规划具有重要的参考价值。
In this article, mathematical statistical method is used to analyze the long term changes of annual precipitation in Xinjiang by using data of long series from precipitation stations, and the representativeness of the short series data of the time periods 1956 through 2000 are assessed,1956 through 1979, 1971 through 2000 are assessed, 1980 through 2000. Based on the analysis, the article provides important references for selection of proper hydrological series and water resources planning and assessment.
