The algae were chiefly distributed in middle intertidal zone and lower intertidal zone 潮間帶海藻的生態(tài)分布區(qū)以中、低潮帶為主。
( 2 ) along the intertidal zone , the lower of contents of heavy metal exponentially , the farther is from sewage sources . ( 3 ) the concentrations of heavy metal decrease inch by inch from high tidal flat to the middle and low intertidal zone . it is water dynamics that impact on the accumulation features of heavy metals of intertidal 如河套是這五個(gè)區(qū)域中唯一的非河口區(qū),潮間帶沉積物重金屬含量全灣最低;大沽河1東營(yíng)鹽場(chǎng)段緊鄰大沽河河口,大沽河2營(yíng)海段遠(yuǎn)離河口,后者重金屬含量普遍低于前者。
