The Analysis Of The Curremt Protection Situations And Technical Srategies Of Shanxi Ancient Trees

The ancient trees, are the heritages that left by our ancestors and also one important partof the valuable resources and historical relics, at the meanwhile, they are living pricelesstreasures. As it is known that, building one famous garden is easy while reserving an ancienttree is difficult. Therefore, regardless of its value on ecological, social or economical, it is ofhigh precious, even more valuable for research study, tourism usage and historical meaning.However, we have no idea about the number of ancient trees and how the present situation idfor the reservation of them, as well as the existing problems, furthermore, how can we takecare of these trees? All the above questions are urgent and essential to solve, we have to putthese questions on the agenda.In order to have a deep understanding of the reservation on trees, this thesis isaccomplished by making surveys, reading literatures and related books and thesis. In twoyears, we have a detailed research on the number of the old trees, the species of old andfamous trees, their growing conditions, management and the reasons for their diseases as wellas the protection approaches. The rescue actions include setting up electronic archives, usingGPS on some trees, finding out the reasons of the weakening trees, etc. Finally, we have got afruitful result which contain the techniques of maintenance and rejuvenation trees, someadvice of how to preserve and make good use the old trees which set a good example ofprotecting and cultural transmission for Shanxi province and Taiyuan municipal. The researchshows that:1. The number of the old and famous trees is36342. which includes13978trees withoutmanaging, containing the oldest trees(which the tree age is more than300)4606, the lessolder ones (tree age between100and299)26206, the number of species trees is73, totally22361trees can be found. Most of the trees are locust, pine, elm, cypress, poplar and ginkgotrees, among which locust trees with the largest number of4300, take a proportion31%, thenis the cypress, with number of2850account22%, pine trees, elm trees and poplar trees, withthe number of5000, account15%or so, others such as oak trees, ginko and Chinese jujubetrees account about22%. The first two oldest trees, with65%of them, appears to beweakening on different levels, even worse for the oldest trees existing more than1000years. In term of taking care the old trees, Shanxi province have issued two laws, one is for thegreening and the other is for the protection, since then, protecting the ancient trees under thecover of laws make sense.2. According the survey, which aims at finding out the living environment and reasonsfor their weakening, a conclusion was make that the problems are mainly caused by humanbehavior. In order to protect the old trees, we can learn a lesson from the other areas wherehave successfully take measures protecting ancient trees, from whom, we learned that we canimprove the underground living conditions of trees, protecting the tree body, fortifying itstrunk, repairing tree holes, etc. Except that, to get a further understanding and a detailedanalysis of its living influential elements, we should determine the physical and chemicalproperties of its nutrients on a regular basis.3. The conclusions made by this survey have proposed some relatively complete keypoints on how to maintain and fortify trees, that is, improving the underground and surfaceliving environment, protecting measures by supporting and strengthening the tree trunk,curing trees disease, anti-decaying approaches, repairing tree holes and decorating. Besides,ways to protect the tree holes also contain opening tree holes, closing, fulfilling them andsetting a lightening rod, etc.
