By establishing an AHP-based assessment index system and assessment model,and applying detection technology that is convenient and harmless for ancient and famous trees,this paper is significant for investigating and assessing the health state of ancient and famous trees,and protecting the limited resources. Fourteen indexes such as growth vigor,disease and pest were selected from the perspectives of overall situation,canopy,trunk and root,and AHP(applied analytic hierarchy process) was applied to define weights of these indexes. According to the results,top 3 indexes in terms of weight are tree vigor,treetop death,internal decay and hole,while the indexes with lower weight are parasitism,root damage,ventilation and permeability. On the basis of assessment model and method as well as field investigation,health grade of ancient and famous trees(A) can be obtained. By grading the health of ancient and famous trees into 3 levels,each level indicates a certain health state,so managers can take corresponding maintenance measures to develop the best ecological and social value of these trees.

Yu Yam Ancestral Garden is one of the four famous gardens in Lingnan,*** study was carried out with the methods of survey and analysis,field measurement and selecting spatial samples methods,dividing Yu Yam Ancestral Garden into 11 plots,for undertaking initial quantitative research on the three-dimensional green biomass(TGB)and environmental ecological benefits(EEB)of the *** results showed thatthe arbor played a decisive role in TGB of the Yu Yam Ancestral Garden sample plot,in which the maximum contribution value was evergreen *** the Pearson correlation significance analysis was carried out on 11 indicators of the plant morphology and the TGB of the trees-shrubs,drawing a conclusion that the main influencing factor for TGB was the ratio of trees-shrubs,and the simulation equation was Y=2,357.67X3+*** of the plants was positively correlated with TGB.A very good way of understanding of the correlation between the TGB of plants and their EEB was proposed,which could provide objective and quantitative theoretical reference data for the plant arrangement of arbor,shrubs and grasses in artificial garden green *** is helpful to understand the importance of artificial garden green spaces ecological value.
