中文摘要 | 事業區為森林經營上重要的林地區劃單元,也是編定經營計畫據以實行的基本規 劃單位。眾所週知,唯有透過良好完善的經營計畫規劃,方能達成森林經營之目標。因此, 深入瞭解各事業區之特性及各事業區彼此間之相對關係,將是從全島尺度為考量時的最重要 課題之一。 而本研究即在於發展適當方法, 利用高程及土地利用型資訊將現有國有林地的 37 事業區與 3 個實驗林予以適當分群,以便增進對各事業區特性的掌握。研究中,透過相 似度矩陣的群團分析,將 40 個事業區分成 6 種高程型群或 5 種土地利用型群,且兩者間 亦可相互整合。由於各項結果均能獲得合理的生態解釋,充份顯示出所發展分群模式頗具實 用性,值得未來應用於相關之分群工作。 |
英文摘要 | The working circle is not only the basic unit for delineating forest land but also the planning unit for operating management plan. As we known, in order to achieve the goal of forest management, a well organized planning is necessary. Therefore, the well understanding of the characteristics of working circles and the relative relationship among working circles in one of the important issues in the scale of Taiwan island. In this study, based on elevation and land use type information, a classification approach was developed for classifying the working circles into groups in order to have better understanding of the characteristics of working circles. Using matrix cluster analysis of similarity, 40 working circles were classified into 6 elevation groups or 5 land use groups. The integration between 5 elevation groups and 6 land use groups was interpreted ecologically very well. In final, based on 6 elevation groups and 5 land use groups, a scheme of working circles was established. |
