會員們

 

非常久違了由於去年颱風‘山竹’對香港樹木造成歷史性的破壞,所以到截稿為止,本會眾多執委依然忙著處理其後遺症,遺憾地缺乏時間去處理會務,為此帶來的不便,敬請諸君多多包涵原諒。

 

由於香港電郵發送系統的限制,本會簡短的信息發送,早在兩年前已經由 Facebook 取代。  有關本會近評香港樹藝行業發展的FB文章,可以前往以下連結取得:

颱風對東亞沿海城市樹木,雖然經常造成巨大破壞,但國際上在這方面的研究,卻是寥寥可數。  反觀樹藝學當中精髓,往往在於都市樹木的生物學和風力結構學。  這兩個範疇,會嚴重影響著樹木保育和樹木風險評估,也不能靠考選擇題,就可以全面掌握。  有見及此,本會一直在努力搜集這方面的資訊和舉辦講座,來提高會員們的專業水平。

 

以下講座是講者花了一年努力研究的技術成果,據聞已有英國大學要求選取這項研究,在海外學術期刋公開發表,目前正在排期。

 

這次的講座內容,達到了英國樹藝學碩士論文的水平,光是涉及分析數據用的電腦程式已達40頁,複雜程度可算比唸電腦程式大學學位還高。  當中量度樹幹搖擺數據所採用的廉價 Compact Accelerometers (不是昂貴的 Tree  Motion Sensor) ,可能是全亞洲用作樹木風力研究的第一次。  講座內容涉及學術程度之高,是本會歷來舉辦技術講座的第一次。  樹藝是一門科學,講求研究和理據,並非追求視覺和感觀,與學習景觀美學的行業完全不同,也沒有多大相關。

 

是次講座也會介紹樹藝研究在國際上的要求和水平,可以給有興趣報讀海外樹藝學位的會員們一次交流機會,讓他們窺探報讀樹藝學位究竟需要什麼條件,從而自我評估是否合適。  目前在香港取得海外樹藝學士/碩士的人數已經超過50人,很多都是公務員。  如果取得的是由英國大學發出的樹藝學位,英聯邦、歐盟和美洲國家普遍承認。  行業的發展需要人才,不能只停留在考選擇題的初級階段,這是大勢所趨。 要成為樹藝專業人員,擁有樹藝學歷 (並非林業、園藝、景觀等等) 和專業資格在所難免,這也是國際傳統。

Dear Station Members,

 

CAA is proud to present our 58th session of arboricultural education to benefit our members.  This time it is on ‘Tree motion in typhoons’ to correspond to the tree damage by typhoons in Hong Kong in 2018.

 

This seminar will be the most technical so far in all CAA seminars with academic contents reaching MSc in Arboriculture level.  The focus of the seminar will be on the experimental design & the deployment of compact accelerometers to measure tree motion in extreme wind gusts.  An introduction will be given on the data processing tool of the R statistical analysis method which will be rather new to the China Region.

 

Anyone who is interested to take up a degree in Arboriculture is invited to come to learn about the requirements in such a program, & evaluate your personal abilities to match.  AS more & more arborists in Hong Kong are graduating with a BSc in Arboriculture, the future trend is likely to require such a qualification in tree assessment & tree work locally

 

In Session 58, the details are as follows:
