摘要
风沙流研究越来越受到人们的重视,其中风沙流通量廓线研究起着重要作用。本文总结了3种典型地表(流沙地表、草方格地表、戈壁地表)风沙流通量廓线研究现状及存在问题。由于研究方法、研究区域及集沙效率的不同,风沙流通量廓线函数有指数函数、对数函数、幂函数、分段函数等多种,同一问题不同函数模拟结果差异可达到3倍,难以应用于实际。根据研究中存在的问题,提出风沙流通量廓线研究发展趋势。
People have been paid more and more attention to the research of wind-sand flows,and the mass-fluxdensity profile above wind-eroded sediments research has played an important role.The research on the current development of three different properties about the surface（moving sand,straw checkerboard,gobi）of the mass-flux-density profile research situation has been summarized in this article.Because of different research methods,areas,the efficiency of sand and so on,more than50 functions have been used on the mass-flux-density profile,including exponential function,logarithmic function,power function and Piecewise function,etc.However,these functions are hardly used in practice because of nearly 3 times difference in the same problem simulation results.According to the existing problems in research,the development trend of the mass-flux-density profile will be come up finally.
