【摘要】 以巴林左旗、察右中旗为例,详细分析了典型农牧交错区主要气象灾害发生的孕灾环境、致灾因子、承灾体及灾情。指出该地区复杂多样的地貌、不稳定的气候系统以及农牧业经济文化落后、投入不足、抗灾力不强等是孕灾环境的总体特征;干旱、低温冷害、霜冻和白灾等气象灾害是农牧业的主要致灾因子。进而分析了干旱、低温冷害、霜冻和白灾发生的规律。同时通过对气候变化与致灾因子相互关系分析,得出随着气候变暖,气象灾害发生的频率有增加的态势,尤其是干旱和白灾。更多还原

【Abstract】 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.更多还原
