Complex erosion of wind and water is an effective link between the wind and water process. The coupled wind-water erosion is a process that simultaneously or alternatively reinforces or weakens individual wind or water erosion. The complex erosion by wind and water is different from individual water erosion or wind erosion, which has always induced more serious damage than individual wind or water erosion process. The distribution characteristics, influencing factors, erosion mechanism and ecological restoration were reviewed in detail in this paper.
  Semiarid regions and coastal area are among the most important regions for complex erosion of wind and water. The adjacent regions by the provinces of Shanxi, Shaanxi and Inner Mongolia is the most serious erosion zone of complex erosion of wind and water in semiarid regions, belonging to the ecotone between agriculture and animal husbandry. The length of eroded coastal line amounts to one-third of the entire coastal line of China. Coastal erosion region is characterized by popularity, diversity and aggravation.
  Erosion characteristics are different because of complex natural and human factors in different zones. Systematic analysis was done from the progresses and shortcomings in the study on complex erosion of wind and water from the aspects of erosion characteristics, soil properties, sediment yield, erosion energy in semiarid regions and erosion characteristics, storm surge in coastal area. A summary was made on the effects of biological and engineering measures on eco-restoration.
  The research trends of complex erosion of wind and water were prospected and summed up, and the future studies will focus on the following three aspects: the mechanism of erosion, evaluation of erosion and mechanism of ecological restoration.

Key words: complex erosion of wind and water in coastal area, complex erosion of wind and water in semiarid regions, ecological restoration, soil erosion, storm surge
