| Abstract: | Research and analysis were carried out of the depositiondistribution and amount of the 930505 extremely severe sandstorm occured at Jinchang, east Gansu corridor. The main results are as follows: (1) The dust deposition of the sandstorm corers 80.7 percentage of the tatal area of Gansu Province. The totaly amount of dust deposition in Gansu Province is estimated to reached 1 245.3×104 t.mon-1 with the maximum value of 699.4×104 t.mon-1 in Jinchang area. (2) The active duststorm weather region is about 7.0×104 km2, but the area in which the atmospheric environment was severely degraded is much more larger and reach 35.5×104 km2. |
| Keywords: | East Gansu corridor Desposition of the extremely severe sandstorm Amount of desposition |
