摘　　要：通过云南1975年12月、1982年12月、1986年3月1991年12月、1999年12月出现的低温天气过程对生长于哀牢山以东地区的多种树木所造成的低温危害的调查,并以1975年12月最严重的一次低温天气过程对树木的低温危害调查结果为主,经统计分析得到了云南历次低温天气过程的多个树种的树木受低温危害情况及不同树种的抗寒性。以各树种树木受低温危害的平均受害指数为依据编制了不同树种的抗寒级别表。同时,还对树种生物学特性、树木的生境与其抗寒性的关系,造成树木受低温危害的气象要素,云南的低温天气过程出现的周期进行了分析,以为开展树木引种、选择及种植发展提供科学依据。The damages of trees in east of Ailao Mountains to low temperature in December 1975, December 1982, March 1986, December 1991 and December 1999 were investigated. Taking the investigation results of 1975 as the major data, using the method of statistical analysis, the damage of many tree species in study area and cold resistance of tree species were analyzed, and table of cold resistance of different tree species was formulated in accordance with the average damage index. Besides, the relationship between biological characteristics and cold resistance, habitat and cold resistance was analyzed. The meteorological elements caused the cold damage to trees were identified, and the cycle of low temperature occurred in Yunnan province was summarized.
