會員們:
台中市政府最近發放了 “行道樹修剪標準作業規範”，可從以下的超連結取到：
據聞這本著作是用了兩年時間才寫起，裡面也用了不少現在國際樹藝行業通用的修剪理論和做法匯聚而成。使用的參考文獻，例如 Shigo, Mattheck 和Schwarze 的研究等等，也是國際樹藝行業能耳熟能詳，与國際現行樹藝知識相當接軌。
在文章裡面，也罕有的列出 ‘截頂修剪法’ 的劣病，和修剪切口不採用塗料的原因，也介紹了幾種常用修剪切法和背後的理論基礎。此外，也提出了修剪時期和工序安全，也建議了如何建訂修剪計劃。
在實務操作上，任何的樹木修剪理論，最終還要配合現場的工作進行才能成事。高大的喬木修剪，往往要配合攀樹用锯、油鋸溜纜等等的實務技術才能做到，否則一大套的理論和標準，只會變成望樹嗟嘆、紙上談兵而矣。目前大中華地區空談樹木修剪的人不少，但能同時做到所提出的理論效果也很少，很多都是講完掉頭就走，然後說工人做不到 ! 國際上的樹木修剪，要求每一刀都應該能夠解釋到位，而不是把持 ‘老子是專家，所以老子說了算’ 這種自欺欺人的態度。
樹木修剪可能是目前整個大中華地區內，樹藝行業最薄弱的其中一個環節，也涉及某些專家學者的面子，和承包商的金錢利益，要走正途，並非是一朝一夕的努力就可達成。但願多一些好像上述的技術指南能夠逐步出現，把本地區的樹藝行業繼續推前。
謹此致意!

Dear Station Members,
The Taichung City Govt has recently issued a Roadside Tree Pruning Guide in Mandarin as follows:
http://163.17.209.253/dyna/data/user/g01/files/201307290828060.pdf
which can be downloaded from internet for public use. CAA has studied this Pruning guide, & has found it a good source information in Chinese for the use of the tree workers in the China region.
The Pruning Guide has carefully explained the objectives of pruning, the pruning time, the pruning biology & the pruning methods. If compared to western literature, this Guide may lack detailed information in certain areas. However, the knowledge within is following international research & the work of prominent scholars like Shigo, Mattheck & Schwarze are quoted. CODIT & Structural Pruning are mentioned. Examples & Illustrations are given. In a place where Topping is written in horticultural textbooks, this Pruning guide appeared to be something from outer space to compare with the traditional practices.
Since this Pruning Guide is now online, very soon the rest of the China Region will acknowledge, & may copy. Internet is nowadays widely used in the China Region. This information may spread.
Although the proper procedures are now written out, Tree Pruning is now something that can follow strictly by the book. The structure & health of every tree is different, & the actual work requires more than a scholar on site to perform. Machines cannot reach the interior of the complex branches in a tree & the use of chainsaw is require dot cut thicker branches. Rigging is use to lower heavy limbs where drop cut is not possible. There are still much to learn beside the theories of pruning, to actually perform it on site.
Anyhow, having a Govt Guideline as a public guide for tree work in our territory is a good start, in a place where where horticulture, landscape design & arboriculture are confused as the same. May this kind of good work can continue in the China Region, to benefit our tree planting in time.
best regards,
