Abstract
The characteristics of soil water of different woodlands were studied by the advanced survey methods.The simulation equations of soil water characteristic curve of different stands were set up to calculate the soil specific water capacity,and to determine the range of available water by classifying the soil water in different stands.Among the main plantation species,the range of soil available water of robinia psedoaeacio and its mixed stands is maximal,and the potential capacity of soil available water of returned farmlands is maximal.
