[Sustainable management for farmland shelterbelts].
The spatio-temporal pattern of shelterbelt regeneration is an important issue which determintes whether shelterbelt network produces protective effects sustainably. This article developed a new method of imitating "normal forest" to manage shelterbelts. Based on an administrative village as an organized management unit, each shelterbelt in the organized management unit will be individually regenerated and regulated, until the number of the shelterbelts in each age-class from young to mature ones will be equal, and the shelterbelts in each age-class will be spatially distributed uniformly in the shelterbelt network of an organized management unit. Consequently, this method might temporally ensure sustainable and stable ecological services which are provided by the shelterbelts in an organized management unit.
