中文摘要 | 本省西南沿海,近幾年來,貝類在每年四、五月間,時有暴斃。本文調查受害區域的氣象因子,並分析海水與底泥的化學因子,於1990年7月至1991年6月,每月採樣並分析一次。主成份分析用來區分顯著的影響因子,主要由樣本變異來判斷。結果顯示在貝類暴斃時,有溫度與降雨量的增加,並水體與底泥中氮濃度的增加,這些綜合因子,可能導致貝類的暴斃,所以氣象因子的改變與附近都市污水的排入可能是主因。 |
英文摘要 | The mass death of coastal calm in April and May in southwest Taiwan have been found during recent years. In this paper, climate information and chemical measurements from sea water and sediment near damage area were collected monthly from July 1990 to June 1991. The principal component method was used to identify significant factors among sample variabilities. Results showed that increasing temperature, precipitation, and nitrogen concentration near coastal area may act as combined factors to cause the mass death. In conclusion, climate change and domestic pollution from nearby ground maybe responsible for the mass calm death. |
