The results showed that at change scale,Cr contents from surface and bottom layers had same change range in Jiaozhou Bay waters of August; at space scale,Cr contents from surface and bottom layers had converse change trend;at vertical scale,Cr contents from surface and bottom layers had similar change. At regional scale,Cr content from surface layer was more than that from bottom layer in Jiaozhou Bay waters except stations A3 and A6; at stations A6 and A3,Cr content from surface layer was less than that from bottom layer. It illustrated that high settlement area of bottom Cr content was in estuary of Haibo River and sunken waters of bay mouth.Therefore,the source and special topographic features decided high settlement area of Cr content in Jiaozhou Bay waters.展开更多
