Abstract: This study focuses on using techniques such as digital terrain model (DTM), geographic information system (GIS), and decision support system (DSS) for forestland ecosystem classification and suitability analysis of the Liukuei Experimental Forest of Taiwan Forestry Research Institute. The content includes the delineation of ecosystem units using DTM, the development of a hierarchical ecosystem classification system using GIS and multivariate statistical analysis, and the establishment of a forestland classification DSS with an application on site selection of a Taiwanese native species – Taiwania (Taiwania cryptomerioides). The results indicate that DTM is a fast, easy, feasible, and automatic approach for delineating ecosystem units of different spatial scales. The developed hierarchical ecosystem classification is a satisfactory scheme for Liukuei’s forestland classification because the developed scheme coincides with the terrain characteristics along a continuum. The established DSS can effectively and feasibly analyze forestland classification under different spatial scales. Meanwhile, the system can easily perform site selection for Taiwania. From the results, it is concluded that techniques such as DTM, GIS, and DSS are useful for forest managers in the reasonable planning of forestland classification and management practice. In addition, the ecosystem approaches obtained from the Experimental Forest can be extended to island-wide forestland classification in Taiwan.
本研究旨在應用數值地型模型,地理資訊系統,決策支援系統等技術於六龜試驗林之林地生態系分類和適宜性分析研究,內容包括利用數值地型模型粹取生態系單元、利用地理資訊系統和多變值統計方法研發階層式的林地生態系分類體系、以及建立林地分類決策支援系統,並以台灣杉之適宜性分析做為應用個案。研究結果顯示,數值地型模型可自動、快速、有效地粹取不同空間尺度的生態系單元;研發的階層式林地生態系分類體系亦符合六龜試驗林之地形特性;所建立的決策支援系統,可簡易地提供林地分類和台灣杉適宜性分析之用。由研究結果可歸納結論如下: 數值地型模型,地理資訊系統,決策支援系統等技術之應用,可協助森林經營者合理、有效地規劃林地生態系分類和適宜性分析,除此外,本研究執行六龜試驗林林地生態系分類所建立的方法與架構亦可提供台灣全島林地生態系分類之用。
