江苏省若干代表站年降水量的多年变化和系列代表性分析

Analysis of Yearly Variation and Sequence Representation of Annual Precipitation of the Several Repre sentative Stations in Jiangsu Province

利用长系列雨量站资料,采用数理统计法分析了江苏省年降水量的多年变化,对1956～2000年、1956～1979年、1971～2000年、1980～2000年等短系列年降水量的系列代表性做出了分析评价,为合理选用水文系列提供了依据,对江苏省水资源调查评价和水资源综合规划具有重要的参考价值,可在生产中应用。

Based on annual precipitation data of long series rainfall stations,this paper uses the mathematic statistics method to study yearly variation of annual precipitation and sequence representation of short series an-nual precipitation,such as1956-2000,1956-1979,1971-2000,1980-2000year,etc.This provides basis for rational selection of a series of hydrology and is significant in investigation and appraisement and synthetic plan of water resources;the result may be applied to the industrial and agricultural production.
