The present study analyzed sandstorms in Harbin, a city in Heilongjiang province in northeastern part of China. Based on the available ground observation data from meteorological stations in Harbin from 1961 to 2010, investigation was conducted for temporal and spatial distribution characteristics and weather conditions. 48 samples of dust collected from two sites were studied in laboratory. By testing the major and trace elements in samples collected, along with Nd isotope content, the component characteristics of these samples was determined. Annual change in law of sandstorm occurrence was found. Increase in occurrence of dust and sand was particularly obvious since 21st century. Occurrence of sandstorm frequency in different seasons was not same. It was high during spring and fall while low during summer and winter. Occurrence of sandstorm in Harbin was potentially related to direction of strong-wind, and winds from southwest was predominant; Horqin sandy land and Otindag sandy land was deemed as far-forth mass source, and the farmland and desertification area around Harbin was near-source. ??
