In order to investigate the changes of soil moisture in different soil layers within the depth of 0—600cm under different vegetation in Zuoyun Town in spring,we determined the soil moisture of five different types of vegetation such as Arbor woodland(Ulmus pumilaand Populus simonii Carr),shrub woodland(Caragana Korshinsk and Hippophae rhamnoides),and grassland.The results showed that soil moisture of different vegetation had different patterns.The average moisture content of grassland was the highest.Caragana korshinskii was lesser and Ulmus pumila was the least in spring in Zuoyun mining area,the average soil moisture of the grassland was 0.3%higher than Caragana Korshinsk while 3.8% higher than Hippophae rhamnoides.Soil water of the vegetation land in the area was the difficult unavailable water.Each profile of the vegetation land in the 200—400cm soil layer existed dry soil layer which had developed mild dry soil layer,moderate dry soil layer and severe dry soil layer.Water cycle was mainly ground water cycle,and didn′t exist basically groundwater circulation.Soil-plant-atmosphere water cycle model was formed and belonged to abnormal water cycle type.
