| 摘 要： | 通过对磴口绿洲防护林冬季相不同配置模式的7个典型林网进行防风效应和经济效益测算，得出：乔木防护林防风效能和气流均一性优于小乔木和灌木：在结构良好的乔木林网中，蓄积存量达到30m^3．hm^2即可保证林网具有可靠防风效益；在防风效能、蓄积生产率以及经济投入方面，窄带密集渠道林明显优于占地面积较大的宽带防护林。

| Abstract: | Windproof effect and economic efficiency of 7 typical forest network of different allocation models on winter facies of the oasis protection forest in Dengkou were conducted.Result shows that the windproof potency and the flow homogeneity of the tree protection forest surpass the small tree and the shrub;in well structured tree network,volume with 30 m3·hm-2 can ensure the forest net the reliable windproof benefit;in the aspects of windproof potency,accumulation productivity as well as the economical investment,narrow band crowded ditch dowling significantly surpasses the broadband protection forest which have larger occupied-area. |
