Abstract:: To evaluate the environmental effect of Artificial Forestry-grass Ecological Projects,the microclimate of artificial vegetation was studied by fixed observation in Ansai.Artificial vegetation and natural vegetation were selected to measure meteorological factors of near-surface layer such as the dynamic and water-heat condition of air,the water-heat condition of soil,and at the same time to make comparative observation at adjacent open sloping field.The results were abtained as follows: the returning farmland into forest and grassland could cause the responses of underlying conditions,vegetation-island effect such as temperature dropping,humectation effects under the summer weather conditions exists.Compared with natural vegetation,the diumal air temperature reduced 2.2℃,the air relative humidity increased 1.97%,the wind speed was weaker and the soil condition was better.The improvement of microclimatic conditions is one of main characters to show the environment impact of artificial vegetation restoration.
