摘　　要：为全面评估古树健康状况,及时制订和调整复壮方案,以北京动物园内42株古树为研究对象,运用层次分析法(AHP,analytic hierarchy process)从整体情况、树冠、树干、根部、立地条件5方面选取树势、倾斜度、树洞、顶梢枯死、树干腐烂等19个评价指标,并用Delphi-AHP法确定各指标相对权重,建立古树健康评价模型。结果表明:树洞、树势、树干腐烂、可见根系损伤等是影响北京动物园古树健康程度的主要原因。将古树按健康值分为4个级别,发现42株古树健康状况以健康状态为主,整体生长良好。评分结果表征树势强弱,与实际调查情况一致,该模型具有较高的适用性。In order to comprehensively assess the health status of ancient trees and formulate and adjust the rejuvenation program in a timely manner,42 ancient trees in Beijing Zoo were taken as the research objects,and 19 evaluation indicators such as tree potential,inclination,tree holes,apex dieback,and tree holes were selected from the five aspects of the overall situation,crown,trunk,roots,and stand conditions by applying the hierarchical analysis method(AHP,analytic hierarchy process).The Delphi-AHP method was used to determine the relative weights of the indicators and establish the health evaluation model of ancient trees.The results showed that tree holes,tree potential,trunk decay and visible root damage were the main reasons affecting the health degree of ancient trees in Beijing Zoo.The ancient trees were categorized into 4 levels according to their health values,and it was found that the 42 ancient trees were mainly in a healthy state,and the overall growth was good.The scoring results characterize the strength of the trees,which is consistent with the actual investigation,and the model has high applicability.
