中文摘要：
为了了解扎龙湿地对小区域气候的调节作用及其变化趋势。利用MANN—KENDALL检验等4种气候变化趋势分析方法，分析了扎龙湿地周边区域的富裕、林甸、社蒙、泰来气象站1957--2002年最高、最低气温的变化特征。结果表明，最高、最低气温存在明显的不对称变化，在部分时段还存在着反向变化趋势；最低气温的变化还明显地存在着气候突变的特征；这种极端气温的不对称变化，使该区域气温的日较差有明显的递减趋势。R／S分析（改变尺度范围分析法）表明最高、最低气温的变化存在明显的Hurst现象，该区域气候变暖有趋于减缓的趋势。
英文摘要：
The climate variation of the Zhalong Wetland and its accommodation effect on the small area are investigated with four ways of climate analysis （for example, Mann-Kendall method） based on the monthly maximum and minimum temperature data in 4 representative stations in Zhalong Wetland. An analysis of the variations of mean monthly, seasonal and annual maximum and minimum temperature is made. The results show that the maximum and minimum temperature exist an obvious asymmetry variation and obvious anti--variations at some stages. Additionally, the change of minimum temperature has its climate sudden change characteristic. ：Based on R/S analysis of the maximum and minimum temperature, the variations of the maximum and minimum temperature had evident Hurst phenomena. In the area, the climate warming tends to be slow.
