摘要
研究了兰州气候变化特征及其城市化发展对局地气候的影响,发现80年代之后,兰州年平均温度相对于60~70年代平均气温的上升幅度是全省平均气温上升幅度的近4倍,其他要素的年、季变化均表现出明显的特征。兰州城市与郊区年、季平均气温差、平均最高和最低气温差有逐渐增大的趋势;年、季降水日数差。
Features of climatic variation of Lanzhou and influences of urbanization development on local climate of city and suburbs are studied. The results show that the ascent size of mean temperature in Lanzhou since 1980's is about four times as compared to that of the Gansu province relative to 1960's~1970's.The interannual and seasonal variational characteristics of other factors is obvious.The differences of the annual and seasonal mean temperature、mean maximum and minimum temperature between Lanzhou city and its suburbs are gradually increasing.The annual and seasonal differences of rain day and the sunshine duration are obviously decreasing.
