| The paper analyses the factors that lead to the main meteorological disasters by using Balinzuo Banner and Chayouzhong Banner as presentative areas. It investigates the characteristics of disaster-forming environments such as sophisticated terrain,unsteady climate system and backward economy,and the main disaster-causing factors such as drought,chilling damage,and frost and snow disaster.Furthermore,it researches the distribution law of the main meteorological disasters.Based on the correlation analysis between climatic changes and the disaster-causing factors,it puts forward that the occurring frequency of meteorological disasters tend to increase with the climate warming,especially that of drought and snow disasters. |
