Based on the current situation and symptoms of the trees' growth in the Humble Administrator's Garden,this paper put forward corresponding monitoring and early-warning standards and technical measures of the ancient and famous trees protection in the Humble Administrator's Garden *** aim of doing this is to establish a scientific basis for the protection of the ancient and famous trees in the Humble Administrator's Garden by setting up systematic fundamental data,dynamic protection standard grades and technique measures of protecting the *** main symptom of trees in the Humble Administrator's Garden is the erosion and decay of the tree *** tree trunks need technical protection,which holds 65.22% of the total sum of trees in the Humble Administrator's ***,much more emphasis should be paid in strengthening technical protection procedures of monitoring and early warning of the tree trunks in the future protection of the ancient and famous trees in the ***,the rejuvenation technique of rooting zone and rooting system,tree pruning technique as well as tree supporting measures according to the specific condition and symptom of the trees should be concerned with in order to protect the ancient and famous trees in the Humble Administrator's Garden in a more scientific and effective way.

The field investigation of the present situation of ancient and famous tress in Lingering Garden was conducted, the results showed that there were 18 trees, belonging to 13 species, 12 genera and 10 families. 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.

The paper had studied growth situation and disease symptoms of ancient trees in Surging Waves *** were 14 ancient trees belonging to 10 genera of 9 families,with tree age of 120-260 *** trees had been well protected *** were 9 ancient trees growing well,occupying 64.29%,which were Ginkgo biloba,Cupressus funebris Endl.,Podocarpus macrophyllus,Zelkova schneideriana Hand.-Mazz,Cinnamomum camphora(L.)Presl,Buxus sinica,and Wisteria sinensis(Sims)*** were 5 ancient trees needing to be protected preferentially,occupying 35.71%,including Ligustrum lucidum,Osmanthus fragrans and Pterocarya *** disease symptoms were trunk rot and hollow *** on these symptoms,the paper had proposed protective measures for Ligustrum lucidum and Osmanthus fragrans:① enclosing eroding holes on the trunk;② clearing up eroded woodiness on the surface of trunk,disinfecting and applying anti-corrosion protectants;③ filling eroded holes of the *** measures for Pterocarya stenoptera included:① clearing up the inner part and interior walls;② disinfecting the inside and interior walls of holes;③ applying anti-corrosion protectants.

Growth conditions,symptoms of ancient trees in the Master-of-Nets Garden were investigated,it was found that there were 6 ancient trees about 120-920 years old in this garden,belonging to 5 genera and 5 *** speaking,ancient trees in this garden grow well due to the proper protection,and 3 of them need only regular management,specifically,Pinus bungeana Zucc.,Podocarpus macrophyllus(Thunb.)***,Wisteria sinensis Sweet in south yard of Dianchun Yi(the Peony Study),while another three need key protection,specifically,Chaenomeles sinensis Koehne,Sabina chinensis(Linn.)Ant.,*** Sweet,2 of which need corrosion prevention and filling protection,and another one needs comprehensive techniques for the rejuvenation of tree *** view of symptoms of these 3 trees requiring key protection,corresponding techniques were proposed as below:3 steps for protecting *** Koehne(*** and sterilizing tree holes,painting anti-corrosion protective agent;*** holes;*** holes);3 steps for protecting *** Sweet(*** up rotten xylem;***-corrosion and sterilization processing for trunk;*** anti-corrosion agent);4 steps for ***(Linn.)Ant.(*** climbing plants around it;*** rotten xylem;*** holes;*** rhizosphere and rejuvenation of the tree).
