中文摘要 | 本研究旨在測試台灣現有地理資訊資料庫,應用於建構三種林型數量分佈模式之 可能性。利用海拔高度、坡向及土地利用型資訊,可發展出三種數量分佈模式,分別為絕對 模式、林型相對模式及地形組合相對模式。其中,絕對模式係以各林型於不同地形組合分佈 面積為計算依據;林型相對模式係以各林型分佈面積為100%,計算其於各地形組合分佈百 分率;地形組合相對模式則是以特定地形組合為100%,計算不同林型的分佈百分率。研究 中以大甲溪事業區為實証分析之對象,利用現有地理資訊系統資料庫,建構六個主要林型分 佈之各種模式。結果顯示,三種模式的綜合使用,可以充份表達主要林型分佈之特性,並可 提供數量式資訊,做為經營上之參考。 |
英文摘要 | The purpose of this study is to test the possibility of developing 3 kinds of quantitative distribution models based on the current GIS data base established by the third forest resources and land use inventory in Taiwan. Applying the elevation, aspect, and land use information, 3 kinds of quantitative distribution models could be developed to describe the characteristics of vegetation distribution: the absolute distribution model, the relative distribution model based on forest types, and the relative distribution model based on topographic (elevation-aspect) combination. Ta-Chia work circle was selected as the study area. Using the elevation, aspect, and land use information, 3 kinds of distribution models for 6 major forest types were be constructed. The results indicate that integration of these 3 kinds of distribution models was helpful in describing the distribution characteristics of the 6 major forest types and offering quantitative information of management. |
