摘　　要：通过冰雪灾害后的冻害调查和多次恢复调查,探讨了桉树冻害评价指标与恢复能力的相关性及其对桉树耐寒性评价的适用性,从灾后恢复水平评价了多种桉树和无性系的耐寒性,总结了不同种类和无性系在不同纬度、不同海拔、不同年龄和不同恢复措施下的恢复能力和恢复特点。Based on the results of serial surveys on the freezing catastrophe in southern China,the relativity between freezing damage indices and the recovery ability of eucalyptus and the appraisement veracity of freezing damage indices was analyzed.The cold resistance of several Eucalyptus species and clones were appraised on the recovery level.Analysis was made on the recovery ability and recovery traits of different species and clones at different latitudes,altitudes and recovery measures.
