摘　　要：利用云南省4个研究区迪庆、丽江、昆明和西双版纳1960-1990年的冬季平均气温及降水等资料分析了近31 a来云南的气候变化以及月气温、降水等年内分布,得出的结论是:1960-1990年间云南典型地区的冬季平均最低气温增温速度由北到南分别为每10 a增温0.475℃,0.422 6℃,0.254 6℃和0.348 8℃,而冬季平均最低地面温度增温速度为每10 a增温0.871 3℃,0.450 6℃,0.446 6℃和-0.418 3℃,气温的增温速度超过了全球气温增速,气候变暖将对这一气候敏感区产生一系列重要的影响。Based on datas of average winter temperature and precipitation of Diqing, Lijiang, Kunming and Xishuangbanna from 1960 to 1990, climate changes and characters on month temperature and precipitation were analyzed. The results showed that the lowest average temperature of winter has rised with liner trend of 0. 475℃/10 a, 0. 422 6℃/10 a, 0. 254 6℃/10 a and 0. 348 8℃/10 a from the north to the south of Yunnan in 1960--1990,in the same period, the lowest land temperature of winter has rised with liner trend of 0. 871 3℃/10 a,0. 450 6℃/10 a, 0. 446 6℃/10 a, --0. 418 3℃/10 a respectively, which will produce a series of important influence on this sensitive area. This paper provides theories for social economic, environmental and sustainable development.
