Abstract: On the basis of analyzing the definition and aims of sustainable management of shelterbelts,the ideal structure of sustainable management of shelterbelts/windbreaks was put forward firstly.Then,taking square sheltemets as a studying object, some essential conditions for constructing sustainable management model of shelterbelts/windbreaks were presented after analyzing elements of spatio-temporal structure state of sheltemets such as management scale,regeneration ability,regeneration age of shelterbelt and regeneration pattem. In addition,according to the relationship between networks ring and belt quantity,spatial position and age distribution of shelterbelts were demarcated and quantified,and the distance function among belts to be removed was defined, to give expression to the seperation degree of belts to be regenerated.Furthermore,a sustainable management model of shelterbelts/windbreaks was constructed to arrange the large area shelterbelts in the temporal and spatial scale by the even degree of regenerated belts distributed in the shelternets system,and determine the transition of distribution state and dynamic process of age structure.
