摘要: 本文采用1950--1990年全国大体分布均匀的350个站的降水资料,分析了近40年我国降水量的时空变化特征及不同年代降水量对植物气候生产潜力的影响。Abstract: Features of space-time variation of precipitation during the recent 40 years in China and its influences on plant climatic productivity were analysed based on the data from 350 meteorological stations evenly distributed all over China from 1951 to 1990.The results show that rainfall significantly changes with time and region,and its influence on crop yield is becoming smaller.
