摘要：Using investigation on Cd in May and August,1990, this paper analyzed the spatial-temporal changes of Cd sources and the influences on spatial-temporal changes of Cd in Jiaozhou Bay. The horizontal distributions in May and August were different, and the vertical variations in different sampling sites were also different. The major Cd sources were the wharf and atmosphere deposition, whose source strengths were 1.02 μg L-1 and 1.26 μg L-1, respectively. From May to August, the major Cd source was changing from the wharf to atmosphere deposition, resulting in the changes of the source strengths and the source input locations, and therefore the spatial-temporal changes of Cd contents in the bay.
