摘　　要：对扎龙湿地1951—2005年逐年年均温和年降水量变化资料进行分析.结果表明,50多年来,扎龙湿地平均气温呈上升趋势,70—80年代气温较为稳定,90年代以来,气温呈明显增加趋势的特征,与全国气候变化趋势完全一致,同时也与全球气候变化的趋势保持较高的一致性.扎龙湿地降水量呈现出波动下降趋势,但下降幅度较小,与东北地区降水量变化趋势基本一致.By analysised the yearly average temperate and precipitation of the Zhalong wetland in 1951--2005 years, results indicate that since more than 50 years, the Zhalong wetland average temperature has assumed the trend of escalation. The temperature is stable relatively in70-80s. Since 1990s, the temperature was significantly increase tendency of characteristic. This trend is consistent with the national climate change trend, also completely consistented with global climate trends. The Zhalong wetland precipitation presents the fluctuation declining trend, but the decline rate is small. This trend is consistent with the northeast area rainfall.
