中文摘要 | 經營計畫編定過程中,為資訊之收集,需先行進行檢定調查。於檢定調查之地面樣區設置上,缺乏簡單且有效的作業方法以資遵循。本研究之目的即在於發展一套適用於事業區範圍的樣區分配方法,利用有限的樣區,做最適當的分配,以便獲得最多資訊。實証分析以太平山事業區為試區,先利用現有數值地形及土地利用型數位資料,分析各志地利用型之高程分佈特性。接著配合所設定之初始參數,依面積比例之方法,經適當調整,求出總樣區數及其分配之情形。然後再應用直方圖等化法配合高程分佈資訊,計算出各高程級之樣區分配數目。結果顯示,從原設之100個樣區經調整為124個樣區,並順利完成各樣區之高程分配。整個作業流程因自動化程度高,操作簡單,且能有效提供樣區設置參考資訊,具有其高之實用性,值得推廣使用。 |
英文摘要 | In order to collect the management information, inventory needs to be conducted on the ground in the preparation stage of forest management. But, a simple and effective method for laying out the plots is absent. The purpose of this study was to develop an approach to allocate plots, and use the limited plots to collect the most imformation on the scale of a working circle. The Tai-Ping working circle was selected as the study area. First, digital terrain model and land use data were used to construct an elevation distributions of the land uste types. Next, some litial paramenters were decided and used in the process of allocating plots. Allocation of the plots was to be conducted under proportionality and with necessary adjustments. Finallyk a process of histogram equalization was used to allocate the plots into elevation classes. The results showed that the process of plot allocation was effective.In this study, 100 plots were set in the inital stage. After the necessary adjustment, 124 plots were decided and allocated into elevation classes. Additionally, operation of the processes was simple and automatic. Therefore, the process is worthy to be recommended in future inventories. |
