| 摘 要： | 利用贵阳市1961～2000年的气温，降水资料，应用统计方法分析了贵阳近40年的气候变化趋势。研究结果发现，贵阳气温有上升趋势，但是上升幅度较小。四季气温变化幅度不大，其中春季气温下降趋势在四季变化中最明显，冬季气温上升幅度最大。降水则呈微弱下降趋势，夏季降水上升，春季降水下降。在此基础上，进一步分析了贵阳从1961年以来的严重冷暖冬时间与多雨少雨年的出现规律．

This research shows that the temperature is rising , but very unconspicuous. There is also an unconspicuous change in four seasons, spring temperature trend descends evidently, and the warm trend is evident in winter than that in the other season. The total tendency of precipitation punily descends, it is rising in summer and dropping in spring.
