主　　题：density of biomass volume shelterbelt wind reduction coefficient permeability porosity 

摘      要：A new structural parameter of shelterbelts, above-ground density of biomass volume, was putforward in this paper. Its practicality in managements of the shelterbelts and its physical meaning of windreduction were expounded. Analytical relations between the new parameter and often-used parameters(permeability and porosity) were deduced. An example was given to show the application of the newparameter in the management of shelterbelts.
