It lacks advanced research on wind erosion, though it is one of the main causes of land degredation and one of the most serious problems in the north of China. Reviewing the past research works on this topic, the main successes achieved during several decades are as follows:①Recognitions of tonality law of regional distribution of wind erosion in northern Loess Plateau, where the climate type is of semi-arid;② Recognition of quasiperiodicity law, including seasonal and long period of 3, 7,14 years etc. annual changes of soil loss by wind erosion;③Descriptive grading of intensities and assessmentation of harmfulness of wind erosion;④Wind tunnel simulations of some single factors effecting on wind erosion;⑤ Studies of principles of controlling measures and practices mainly on sandy farmlands and rangelands and also along the railways and roadways etc..Further needs of researches to solve the wind erosion problems in future include:① Comprehensive research on physical nature, effecting factors and dynamics of wind erosion;② Impact of physical and chemical properties and ground surface characteristics of soils on wind erosion and their feedback mechanics;③Numerical and wind tunnel simulations;④Predictive equation of soil loss by wind erosion;⑤Erosion productivity impact calculator;⑥Interactions of wind and water erosion;⑦ Interactions of global change, landuse and wind erosion;⑧Impact of wind erosion on sustainable development of human society and economy in arid and semi-arid area etc.
