Health Evaluation of Ancient Trees in Beijing Zoo Based on Hierarchical Analysis Approach
摘要
Abstract
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 de-cay 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 ap-plicability.关键词
