Analysis of Asymmetry Variation of Maximum and Minimum Temperature in Zhalong Wetland
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.
