摘　　要：对224团几种典型结构和配置的防护林带进行林业调查,结合林带疏透度和防风效能,分析了各林带的防风效能。结果表明:其防风效益与树种配置、疏透度有密切的关系,乔灌混交林的防风效果优于乔乔混交林,并且乔乔混交林的防风效果优于纯林,防风效益最差的是灌木林。稀疏型林带防风效果最佳,平均防风效能为33.69%,疏透型次之,平均为24.29%,通风型和紧密型防风效果最差,防风效能分别为20.05%、17.91%。林带防护效能较好的疏透度为32%~47%。因此,林带结构应以稀疏型为主,以乔灌混搭(新疆杨×胡杨×柽柳)的配置模式进行防护林的营造。The forestry survey on several shelterbelts with typical structures and configurations was carried out in 224 regiment.The Windproof ability of different types of forest belt was analyzed,Combining forest belt degree of lighting with wind resistance.The re sults show that the Windproof ability is closely related to the tree species arrangement and the degree of lighting.The Windproof abil ity of the mixed forest of trees and shrubs was the best one,the second one was the mixed forests of trees and trees,and the worst one are shrubs.The best windproof effect was of sparse structure shelterbelt,with a average of 33.69%.The next one was of porous structure with a average of 24.29%,and the worst ones were of ventilation structure and compact structure,with the average of 20.05%and 17.91%,respectively.The fineness of forest belt protection was 32%to 47%.Therefore,the shelterbelt structure should be mainly sparse,and the construction of shelter forests should be constucted in the configuration mode of arbor-shrub mix(Xinjiang Poplar×Populus euphratica×Tamarisk).
