Abstract:
In this paper, the monthly and yearly meteorological data and ecology information in the Baiyang Lake from 1955 to 2010 were analyzed to investigate the effects on the wetlands, in order to provide the basis of protection and sustainable development to the Baiyang Lake. The results showed that the local climate of Baiyang Lake varied in recent 56 years with increasing in temperature but decreasing in the precipitation, wind speed, and sunlight. In 2007, the temperature was the highest in the past 56 years, and after 1996, the precipitation was all below the average of 56 years. The precipitation had significantly positive correlation with the annual highest water level, however, the average temperature had opposite correlation with water area. The changes of water level and water area, coupled with the impact of human activities affected the water quality and biological diversity in the Baiyang Lake and the allocation proportion of different types of land use.
