| Abstract: | Based on the investigation and analysis of the change of soil water storage of Robinia pseudoacacia,Pinus tabulaefolia and suitable forest in the Loess Plateau of Weibei,China,the soil water storage capacity of forestland is affected by the interaction of site conditions,canopy shade and forest environment,forming a water self-supply system.Its potential can be expressed and calculated by"forest effective water potential equation MT=ΔEF+ΔRQ-IP".The relationship between water budget and water budget is essentially different between the barren slope and the forest after the forest consumes a lot of water by transpiration.It is concluded that the amount of soil available water storage is closely related to forest canopy action and forest environment change. |
