摘　　要：【目的】风蚀坑不仅会造成植被退化,扩大沙化草地面积,而且加快了荒漠化的进程,使生态环境受到了严重威胁,特别是对土地资源和人类的生产生活造成了很大的影响。【方法】课题组综述了目前针对海岸风蚀坑和沙质草地风蚀坑的形态特征、发育演化、蚀积过程等方面的大量研究,总结了沙质草原风蚀坑形态-动力过程研究领域的主要进展,综合分析了风蚀坑形态-动力过程的研究方法。【结果】现有关于风蚀坑类型的划分方法无法普遍适用,风况和风蚀坑变化之间的关系不明确,且现有研究手段对风蚀坑形态辨识的精度较低。【结论】在今后关于风蚀坑形态-动力过程的研究中,应更注重风蚀坑形态分类的适用性、风况变化与风蚀坑演变的规律性和气候现象对风蚀坑发育影响的不确定性的研究,以期弥补风蚀坑形态-动力过程研究领域的空缺,同时为风蚀坑治理提供更全面的科学依据。[Objective]Blowout not only cause vegetation degradation and expand the area of sandy grasslands,but also accelerate the process of desertification,posing a serious threat to the ecological environment,especially it has had a significant impact on land resources and human production and life.[Method]The research group reviewed a large amount of research on the morphological characteristics,development and evolution,and erosion processes of blowout and sandy grasslands,summarized the main progress in the research field of blowout morphology dynamic process in sandy grasslands,and comprehensively analyzed the research methods of blowout morphology dynamic process.[Result]The existing classification methods for blowout types are not universally applicable,the relationship between wind conditions and blowout changes is not clear,and the accuracy of existing research methods for identifying blowout morphology is low.[Conclusion]In future research on the morphology and dynamic process of blowout,more attention should be paid to the applicability of blowout morphology classification,the regularity of wind condition changes and blowout evolution,and the uncertainty of the impact of climate phenomena on blowout development,in order to fill the gap in the research field of blowout morphology and dynamic process,and provide a more comprehensive scientific basis for blowout management.
