Abstract
東臺灣黑色土分佈於海岸山脈之低丘陵至緩斜地帶，成小片狀與他類土壤間什存在，母質屬安山質集塊岩與凝灰岩，氣候年平均溫度約22℃，雨量1,700~2,000公厘，本研究冀自土壤理化性與相關因子以探索其成因。 土壤剖面性態為深或淺層暗灰棕至極暗灰棕之黑色土直接覆蓋於母質之上，質地屬粘壤類，構造良好，多成細至中之鈍角塊狀或團粒狀，結構濕時粘而帶塑性，乾時甚硬，呈深而潤之裂隙，中酸至微鹹性反應，中至緩透性，有機質尚豐。
Black colored soils derived from andesitic or tuffic agglomerates occur in patches in association with other soils on roiling land and gently sloping hillside of coastal mountain ranges of East Taiwan. They have been formed under 22°C of average annual temperature and 1,700-2,000 mm. of annual precipitation. With the intention of studying the formation and classification of these soils a research on soil chemistry, physics, morphology and forming factors has been carried out. Soil profiles overlying parent rocks range from 20 to more than 100 cm. in depth and from dark grayish brown to very dark brown in color.
