摘要
本文对南水北调－中线调水区域内十个测站自５０年代以来的年降水量进行了研究．不仅考察了各站雨量的趋势变化和周期性变化，更重要的是，就一些水文要素进行了横向的比较分析，即对由北向南降水量的年际和年代际时空变化规律进行了探讨和初步研究． 这可为“南水北调”提供一定的理论依据．
In this paper we study the annual precipitation observed in the ten hydrological stations since 1950 s, and the stations are in the Middle Region related to the South-to-North Water Transfer Project. Not only the tread and periodicity are investigated for the series of precipitation in every station, more important is that, we compare and analyse variation of some essential factors in hydrology from station to station, that is, we investigate and study the regularity of temporal and spatial variation for an...
