台灣柳杉造林歷史回顧及經營方式探討

台灣柳杉造林始於日據時期，自光復前造林面積即開始大幅增長。本研究為了解柳杉人工林決策始末，乃藉由重要學界人物訪談與文獻史料補遺，進行資料整理與分析。結果顯示：光復後柳杉大量栽植之決策，受到學界建議的影響甚大。柳杉的面積迅速擴大，係1965至1977年林相變更計畫的結果。後因鼠害嚴重，乃不再以柳杉做為主要造林樹種之一。依目前各方人士的專業見解，柳杉林的處理不宜一概而論，若能在總體林地分級的規劃下，視其生長現況做合宜的處置，較符合適應性經營的概念。從柳杉造林成因、擴大栽植到不甚理想的栽植現況，反映出百餘年的殖民林業、傳統科學林業，乃至新林業／森林生態系經營等觀念的作用。因而柳杉林之後續處理正可視為適應性經營的操作範例。

The purpose of this study is to explore the whole process of Japanese cedar (Cryptomeria japonica) planting decision making and the availability of following strategy. The data source comes from in-depth interviews of senior key persons and rearrangement of historical literature reviews. The results show that the mass plantation decisions of Japanese cedar after World War II were the influence of the scholars' suggestions. Between 1965 to 1977, Japanese cedar plantation areas rapidly increased due to the process of ”the Stand Conversion Project” from Taiwan Forest Bureau. Several decades later, since squirrel damages are serious, Japanese cedar was not longer considered as one of major plantation species by forest sector. According to current professionals opinions, by using same method to deal with all Japanese cedar plantations is not appreciate way. In stead, the principal of with different treatments based on different growth sites is better management thinking, which also fits the concept of adaptive management. From the species chosen, plantation expansion, and deteriorated condition of Japanese cedar plantations, all these events reflect the forest management paradigm shifts from colonial forestry, scientific forestry, New Forestry to forest ecological management. The future development of Japanese cedar plantations should be regarded as a model of adaptive management.
