中文摘要	[目的]在塔克拉玛干沙漠油田公路机械防沙展示区,对比两种固沙技术的固沙效益及其地形适应性,为工程防沙的优化设计及其应用提供理论依据。[方法]对地形起伏条件下芦苇方格和尼龙网方格沙障的风沙危害状况进行了野外调查。[结果]在固沙方格沙障设置初期,各种地形条件下芦苇方格沙障的沙害类型相对单一,均为半埋危害。尼龙网方格沙障的沙害类型多样,而且在沙丘纵断面上变化很大,在迎风坡和落沙坡风蚀危害发生比例大;在调查区内,尼龙网方格沙障4种沙害类型均有发生,发生的比例依次为:半埋>风蚀>全埋>压埋。两种方格沙障防护效益的差异与地形引起强烈风动力空间分异、自身布设方法和孔隙度有关。[结论]草方格地形适应性强,在不同起伏的地貌区均有显著的固沙效果,而尼龙网方格沙障更适宜布设在较平坦的地貌区,而不适于地形起伏较大的地貌区。
英文摘要	[Objective]To compare the sand preventing effects and terrain adaption of two different sand-barriers at sandy-prevention exhibition zone of the Taklimakan Desert petroleum highway in the Taklimakan Desert,in order to provide theoretical basis for application and structure optimization with sand control engineering. [Methods]The effect of reed checkerboard and nylon net checkerboard barrier on blown sand disaster in rugged terrain areas were investigated.[Results]The types of blown sand disaster during the early days of reed checkerboard barrier on the flat land and rugged terrain were relatively single and all semiburied. The types of blown sand disaster with nylon net checkerboard barrier on the dune were diverse and varied greatly among different sites.The proportion of wind erosion was large in the windward and leeward slope.The sequence of blown sand disasters types with nylon net checkerboard barrier was the semi-buried, wind erosion,buried and deeply buried in the investigation areas.The protective effect of two checkerboard barriers on different sites was mainly caused by strong disturbance to the near ground surface wind field and wind speed from dune landform and the setting mode and the porosity.[Conclusion]The reed checkerboard fit different landforms.Sand-stabilizing project with nylon net checkerboard barrier is more suitable for flat sandy land than sites with rugged terrain in terms of controlling blown sand disasters.
