沙障技术演化特点及发展趋势

摘要

Sand barriers are one of the main measures used to prevent desertification and have been widely used in desertification control.Here,we use bibliometric methods and content analysis to summarize sand barrier type,applications and research.Existing problems in research are pointed out and revolution characteristics and development trends of sand barriers are discussed.We conclude that three main driving factors have stimulated sand barrier study:demand,technology and development concept.Developing environmentally friendly technology and promoting industrialization of sand area economies are future directions for sand barrier research.%沙障是风蚀工程治沙的主要措施之一,已在荒漠化防治领域广泛应用.采用文献计量和内容分析法,对国内外沙障应用以来在沙障类型、研究内容等方面的工作进行简要归纳和总结,指出了沙障研究中存在的问题,详细论述了沙障研究规律及发展趋势,认为科技、需求和发展理念是沙障研究的三大驱动因素,发展环境友好的生态技术,促进沙区经济产业化是沙障研究的方向.
