Abstract

Wetlands are among the most important ecosystems on Earth and the major feature of the landscape in almost all parts of the world, it provides a wide range of ecological regulation services and is very important to the atmospheric humidity in a region. In order to recognize the influence of wetland on the atmospheric humidity, this paper takes Beijing-Tianjin- Tangshan region as the study object and quantitatively analyzes their relationship with the help of MODIS satellite images, monitoring data observed with the ground weather stations, wetland data, and other land surface data. This research finds that (1) Globe temporal feature of atmospheric humidity is closed to the seasonal change and alternation. (2) Globe spatial feature of atmospheric humidity is influence by the landform, land cover type. Because study region adjoins to sea, it is influenced by the distance away from coastline. (3) Wetland's spatial distribution influences with the spatial distribution of atmospheric humidity. With the distance away from wetland is bigger and bigger, atmospheric humidity is less and less. However, its change trend is mild.
