A detailed statistical analysis is made of the hour-to-hour temperature, wind speed, relative humidity data, etc, from the Zhalong wetland ecological meteorological station and Qiqihar meteorological automatic station from June to August 2004. The differences of the meteorological elements at different times between different underlying surfaces are found. The evidence shows that differences exist in the monthly mean wind speed, temperature, dew-point temperature, relative humidity, and surface temperature, and that the variation amplitude and the occurrence time of extreme values vary. The difference between different underlying surfaces only helps increase or decrease the daily variation amplitude of the elements. The findings contribute to the further understanding of weather variation regularities and are of referential significance in the fine forecasting of meteorological elements in the Zhalong wetland and the exploitation, conservation, and management of wetland resources in future.
