摘要:
本文对中国长江流域降水趋势进行了分析.指出对月降水量而言,20世纪后50年不同区域出现1不胃的降水趋势变化特征.趋势插补法研究表明中国降水时空分布趋势十分明显.对长江流域长期降水资料分析研究指出夏季月份降水时间更集中,而对年降水而言在一些站则表现出明显的周期变化.

Observed and Interpolated Precipitation Trends and Variability in the Yangtze Catchment Area

Abstract:
Precipitation trends in China with special emphasis on the Yangtze catchment area have been analysed. Significant positive and negative trends for the second half of last century have been detected for different regions on a monthly scale. The interpolation of the trends lead to characteristic spatial trend patterns in China. The analysis of long-term precipitation records in the Yangtze catch-ment area revealed a concentration of summer precipitation within a shorter period of time on the monthly scale and a distinct cyclicity for some stations on the annual scale.
