Abstract:

Through the studies on the shelterbelt management, sub-models of shelterbelt management including windbreak structure(optimal porosity β), relationship between porosity and protective benefit(β0), coefficient of disaster(α), mature height(Hin) and effective interval of protection(Def)etc. were established successfully. Based on the sub-models, the model for continuative economic benefits of windbreak management(CEBWM) was obtained. The parameters and application examples of poplar shelterbelt were also given in this paper. The CEBWM can provide not only technologies for windbreak management, but also important parameters for windbreak planning and designing.

Key words: Windbreak(Shelterbelt), Continuation, Economic benefit, Management model
