土壤风蚀是中国干旱、半干旱地区的主要环境问题之一。综合近年来有关我国不同地区土壤风蚀风洞模拟实验与野外研究成果 ,根据风蚀气候指数和沙尘暴日数的分布 ,指出了我国的风蚀区域与沙尘暴活动中心。
Soil erosion is one of the major environmental problems in arid and semi-arid areas of China. Based on the wind tunnel simulation experiments and the field research results in different regions of China, the wind erosion area and dust storm activity center in China are pointed out according to the distribution of wind erosion index and sandstorm days.
