| According to observations on the microclimate of different models of forest-grass rehabilitation,such as mixed forest,manual shrubbery,wild shrubbery and grass glad,in Ansai experiment station,the main climate factors,such as air temperature,relative humidity,soil temperature,evaporation from water surface and so on,were analyzed.The result shows: the 4 models of forest-grass rehabilitation can significantly reduce average air and soil temperature,increase moisture of both air and soil in June,and have obviously a regulation function.The daily average air temperature changes with a asymmetry one-peak curve,and is 0.41℃～1.2℃ lower than that of bare land.The order of the temperature of 0～20 cm layer soil is: mixed forest |
