- 中文摘要: 大鬼湖?一個位於海拔2 1 0 0公尺,少有人?污染的高山湖泊。夏天(七月)水體有?度層化現象。溶氧量在8? 10公尺間有極大值,乃由冬天冷水沈於該處所致。低溶氧飽和程度與高有機質,使得夏天水層在10?16公尺以下完全 缺氧,無氧層厚達18公尺。冬天(二月)水體完全翻?,上下水?及各離子含量較一致,整個水層溶氧飽和程度只達68 %。營養鹽的資料也顯示,水體在夏天層化、冬天混合。
- 英文摘要: The 2100 m high Great Ghost (Ta-Kuei) Lake, which has been subject to little pollution, was temperature stratified in summer (July). Dissolved oxygen showed a maximum at 8~10m, a remnant of winter water. Low dissolved oxygen saturation values and high organic matter loading caused an anoxia below 10~16 m in summer. The anoxic hypolimnion was 18 meters thick. In winter (Feburary), the lake turned over and became relatively homogeneous. The dissolved oxygen saturation level was at only 68% throughout the water column. Nutrient data also supported strong summer stratification and winter mixing.
