During his lifetime, With the continuous development of society, people pay more and more attention to the construction of ecological civilization, especially the protection of ancient and famous trees. Ancient and famous trees are not only very precious, but also extremely scarce, which shows that the protection of ancient and famous trees has become the top priority of protection work. he has experienced various complicated changes in climate and environment and various diseases and insect pests. After investigation and statistics, the damage rate of ancient trees and pests in Huludao City reached 13.2%, among which 6% were seriously damaged. In view of the above situation, we should adhere to the policy of "prevention first, comprehensive prevention and control", through regular inspection, timely prevention and control, and take effective measures to effectively protect the ancient tree resources in Huludao City.展开更多

On this basis, current situation of ancient and famous trees as well as ecological landscapes formed by these trees in classical Suzhou gardens were analyzed, connotations of these trees elaborated, and relevant regulations taken to identify the grade of these trees. Ancient and famous trees in 9 classical Chinese gardens were investigated, specifically, the Humble Administrator's Garden, the Lingering Garden, the Master-of-Nets Garden, the Mountain Villa with Embracing Beauty, the Pavilion of Surging Waves, the Lion Grove Garden, the Garden of Cultivation, the Couple's Retreat Garden and the Garden of Pleasure. Compared with statistics obtained in 2002, the quantity of ancient and famous trees in these 9 gardens reduced by 11. History and growth state of some trees were introduced, such as Pinus bungeana Zucc. ex Endl., Ginkgo biloba L., Sabina chinensis (Linn.) Ant., Buxus sinica (Rehd. et Wils.) Cheng, Cudrania tricuspidata (Carr.) Bur., and significance of the principle-"right tree for right land" for ancient trees aged 100 years or more was stressed. Moreover, it was stressed that garden protection should also devote more attention to researches on plants.展开更多

The trees’ ages were between 100 years old and 330 years old; 14 trees (accounting for 77.78% of the total trees) required regular management, 2 trees (accounting for 11.11%) required bole antiseptic protection, 1 tree (accounting for 5.56% of the total plants) required protection for its trunk, and 1 tree (accounting for 5.56%) required bole antiseptic protection and rejuvenation. According to the survey results, the monitoring and early warning standard grades were divided, its reasons were analyzed, and finally, the relative protection and restoration countermeasures were put forward.展开更多

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.展开更多
