中文摘要 | 水資源開發是臺灣地區當前的重要課題,其與集水區經營有極密切的關係。而生 態土地分類是集水區經營的基礎工作,其可讓經營者更深入的去瞭解森林立地潛能,並可用 於闡明植群與立地環境間的關係。本研究以瑪家水庫集水區為範圍,以數值地形模型推導物 理環境變數 (包括海拔高、坡度、坡向、水份梯度、全天光空域 ), 並利用 ERDAS 影像處 理軟體進行生態土地分類,其結果將瑪家水庫集水區之立地環境潛能劃分為交大類型,分類 結果利用頻度分析探知各分類單元之物理環境狀況及立地環境潛能,其結果可供日後集水區 經營管理方針擬定之參考。 |
英文摘要 | The exploitation of water resources is an important problem in Taiwan and that is in connection with watershed management. The ecological land classificationis a basis for watershed management that can be used to understand the capability of forest site and to explain the relationship between site and vegetation. The study areas are at Ma-Chia dam watershed in southern Taiwan. Synthetic enviroment index (moisture gradient class and whole light sky space) were derived from GIS data (slope, aspect, elevation). We used the synthetic enviroment index and digital terrain model as datasets and used ERDAS image processing systems as analysis tools to produce six ecological land classification types in Ma-Chia dam watershed. The site capability and biophysical state were discussed by frequency analysis for ecological land classification types. The results will be a guideline for watershed management. |
