| Abstract: | Based on the data from meteorological stations and hydrological stations in the Argun drainage basin in recent 50 years,using regression statistical method,the changing characteristics of annual and seasonal mean temperatures,precipitation and evaporation in the basin were analyzed to understand the response of typical wetland to climate change in the high latitude area of China.The results show that: 1) Overall changing trend of annual and seasonal mean air temperatures have increased since 1960 in an undulated way.The temperature rise trend has further enhanced since the mid-1980.The average temperature in each phase was higher in the upper reaches than that in the lower reaches.The climate trend rate of average air temperature in each phase was 0.4~0.7·(10a)-1;2) In recent 50 years,overall trend of annual and seasonal precipitation changes in the Argun drainage basin has slightly decreased,especially,in summer;precipitation in each phase was more in the lower reaches than that in the upper reaches.The climate trend rate of precipitation in each phase was-3.94~0.52 mm·(10a)-1.3) Since 1972,overall evaporation changing trend in the Argun drainage basin has reduced significantly,especially,in spring and summer,but it has slightly risen in winter and autumn;the evaporation of each phase in the upper reaches was more than that in the lower reaches;the annual,spring’s and summer’s climate trend rates of evaporation were-41.26 mm·(10a)-1,-29.02 mm·(10a)-1 and-19.02 mm·(10a)-1,respectively.The climate change trend in the Argun drainage basin is consistent with that in Northeast China on the whole,but air temperature and precipitation have large change range,showing a pronounced local character. |
