| Abstract: | The climate of Horqin Sandy Land is on the edge of monsoon climate,and the drought/flood climate varied greatly.In this research the historical literature material and the actual precipitation material were used to carry on minutely discussion and research to the rules of drought/flood climate variations in Horqin Sandy Land during the last 300 years.Using the drought/flood index,the drought/flood rank regions were determined and then the region drought/flood stage,the rules of the relatively moist time/arid time appearanceand the regional distribution characteristic were analyzed and elaborated. |
