摘要 Based on the daily temperature and precipitation data during 1961-2007 in 81 meteorological stations of Heilongjiang Province,the climate change trend characteristics of temperature and precipitation in Heilongjiang Province,Shuangyashan area,Baoqing County and Qixinghe Wetland were contrasted and analyzed by adopting the climatology statistics method. The results showed that the temperature change trend in Qixinghe Wetland was consistent with the temperature warming trends in Heilongjiang Province and Shuangyashan area. The annual average lowest temperature was the most obvious in the temperature warming trend,and the annual average temperature was the second. The annual average highest temperature was the third. Qixinghe Wetland had the important regulation effect on the local(Baoqing) climate. The annual precipitation in recent 50 years in Baoqing County,Qixinghe Wetland presented the decline trend and in Heilongjiang Province,Shuangyashan area presented the increase trend as a whole. In the trend which the temperature obviously rose,and the precipitation declined overall in Qixinghe Wetland,the protection of Qixinghe Wetland maybe faced with the restriction of water scarcity condition in the water resources aspect. One of important ways which solved with the water scarcity problem in Qixinghe Wetland maybe was strengthening the artificial effect weather work and using sufficiently the cloud water resources.
