Abstract: Preliminary microclimatic observations on sandy land showed that with the development of desertification environment and increasingly intensified feedback effects occrred on ground surface various elements of nearsurface microclimate are firstly affected. This causes great loss of solar radiation, e.g.it lost up to 572 w/m2 and ground temperature also shaowed great variations.The reduction of roughness and intensifgying of turbulent motion cuaxe wind erosion on land surface.All these climatic elements directly reflect the detrioration of desertification environment.
