摘要
对锡林浩特市城防林的配置模式和其所具有的生态、社会和经济效益进行了初步的研究。结果表明:不同林带对不同高度层的风速降低作用差异很大。灌木树种主要以降低近地层风速为主,对高层风速影响相对较小。与对照相比,城防林带中,无论是从植物种的多样性还是单位面积植物地上部分的生物产量均有很大的变化。
Through the research on the arrangement model and the ecological,social and economic benefits of the urban protective forest in Xilinhaote,there are significant differences among the different forest belts on decreasing the wind speed at different height.The shrub trees mainly decrease the wind speed near the ground with less influence on the wind speed at higher level.Comparing with the control,in the urban protective forest,there are significant changes on both plant diversity and biomass of aboveground vegetation part in unit area.
