摘要: [目的] 研究不同规格沙袋沙障对浑善达克沙地的防风固沙效益、土壤改良以及植被恢复的作用。[方法] 在浑善达克沙地布设1.0m×1.0m、1.5m×1.5m、2.0m×2.0m3种沙袋沙障,并设置对照样地,每块样地均为20m×20m。从地表风速、土壤理化性质、地表植被组成和群落丰富度等方面对沙袋沙障的防风固沙效益进行7a的研究。[结果] 布设1.0m×1.0m、1.5m×1.5m、2.0m×2.0m沙障的样地比对照样地的地表粗糙度分别提高了116倍、62.17倍、12.83倍,而植被盖度分别增加了12.3倍、9.5倍、5.39倍,Shannon-Wiener指数(H)与群落丰富度指数(IMA)明显增大。[结论] 1.0m×1.0m的沙袋沙障综合防护效益最佳,1.5m×1.5m和2.0m×2.0m沙障的防护效果稍差,在7a中土壤的理化性质逐年提高,地表粗糙度先增大后减小。

Abstract: [Objective] The aim of this study was to explore the different effect of sandbag barrier on wind-breaking,sand-fixing,soil improvement and vegetation restoration in Hunshandake Sandyl and.[Method] Analyze the observational data from 1.0 m×1.0 m,1.5 m×1.5 m,2.0 m×2.0 m sandbag barrier plots and control plot,Each plot is 20 m×20 m.Discuss the Sand-fixing function from the following points:the land surface's wind speed,soil physical and chemical properties,vegetation composition and community richness during 7 years.[Results] The roughness of 1.0 m×1.0 m、1.5 m×1.5 m、2.0 m×2.0 m sandbag barrier plot is 116,62.17,12.83 times higher than that in the control plot respectively.And the surface vegetation coverage of 1.0 m×1.0 m、1.5 m×1.5 m、2.0 m×2.0 m sandbag barrier plot is 12.3,9.5,5.39 times higher than that in the control plot respectively.H index and IMA index significantly increase.[Conclusion] The Sand-fixing function of 1.0 m×1.0 m the complex protect benefit is better than others,the Sand-fixing function of 1.5 m×1.5 m、2.0 m×2.0 m sandbag barrier is weaker.The physical and chemical properties of the soil increases every year,the surface roughness first increases and then decreases during 7 years.

Key words: sandbag barrier, Hunshandake Sandyland, soil condition, vegetation restoration
