摘要
区域气候的变化已成为影响当地环境,制约可持续发展的一个重要问题。20世纪80年代以来,全球气候变暖也成为人们关注的焦点。黑龙江省地处中高纬气温明显变暖,近120a来年平均气温上升1.4℃;冬春季升幅最大上升1.8℃,气温突变在1990年前后。从年、季平均气温变化趋势与全国及北半球、全球气温变化的比较,指出年、冬季我国增暖中心在黑龙江省,春季在内蒙北部及黑龙江省,夏秋增暖不明显,但仍有上升趋势。50~70年代黑龙江省及全国各大区域普遍增暖不明显,80年代黑龙江省增暖幅度开始增大,三北地区次之。90年代黑龙江省增暖更加显著,而全国及其他区域上升已达到80年代北方增温幅度。同时指出黑龙江省气温与北半球、全球气温变化趋势基本一致,尤其80年代至今气温都有显著地上升。
The regional climate change has become an important question which has been influenced local environment and restricting sustained development. The research of climatic change aim to improve environment and act as good consultant for our national economy development. Since 1980s, the global climate becoming warmer has been becoming a focus which everyone attention,Heilongjiang climate has changed to warm, the mean annual temperature rise 1.4?℃; the highest annual is 1.8?℃ in winter and spring, the temperature s break occurred about in 1990s . having compared the annual and the four seasons average temperature change tendency of Heilongjiang Province with that of the nation and north hemisphere and global. We concluded that the warmest center of the year and winter located in north inner Mogolia and Heilongjiang Province ; but temperature departure in summer and autumn was not obviously yet ,it had increasing tendency .actually in nearly fifty years , Heilongjiang Province and most of the nations temperature did not rise obviously from 1950s to 1970s, and it was not until 1980s that the temperature of Heilongjiang Province rise obviously ,Sanbei district followed it ,and became much warmer in 1990s,and nation and other district had matched the rise range of the north in 1980s, and it is pointed out that Heilongjiang temperature change tendency is identical with that of north hemisphere and the global. Especially , the temperature has obviously raise since 1980s.
