摘要
Abstract
According to a general rule of a system development which is described as Logistic curve,the developing process of soil and water conservation function of woodland is divided into stages including growing,mature and descending based on the developing speed.The mature stage is defined as the period of sustainable development.The length of the period of sustainable development is influenced by distribution light,water and fertilizer of which distributing coefficient is r and using coefficient is k.Thereby,in oder to raise as the strategies for sustainable development of soil and water conservation function,that the distributing coefficient r and using coefficient k should be adjusted through maipulating composition of tree species in forest,standing hierarchy and standing density to develop rational standing structure,proglong the mature stage,and shorten the growing stage.关键词
