摘要
以河南宝天曼自然保护区的19个树种的5项指标作为评判依据，采用灰色系统理论中的关联度作为测度，对各树种的防火性能进行综合评判，评判结果与实际情况一致，从而为防火树种的选择提供了一种新的科学方法．
Based on the 5 indexes of 19 tree species in Baotianman Natural Reserve in Henan Province, by using relative degree of grey system theory as the estimate, a synthetical appraisal was given of each tree species' function of fire prevention.
