The article is based on nation nature science foundation of china, " biogeochemical cycling of pollutants in complex environments of tidal flats in the yangtze estuary " ( no. 40131020 ). the author chose open tidal flat of dong tang chongming yangtze estuary as research object and set up typical section plane so that under the good condition, the author measured hydrology element, total nitrogen and total phosphor index
本文依託國家自然科學基金重點項目「長江口濱岸潮灘復雜環境條件下物質循環研究」 （批準號： 40131020 ） ，選擇了長江口崇明東灘敞開型潮灘為研究對象，設置典型斷面，在平靜天氣條件下，實測了水文、地球化學要素，獲得了水位、流向、流速、 tn及tp等指標6000多個實測數據，著重對長江口潮灘水動力過程、 tn和tp的動力輸移過程進行研究。 -
The author emphasized on the research of the process of tidal flat hydrodynamic and the process of total nitrogen, total phosphor dynamical transportation and got the conclusion as follows : ( 1 ) open tidal flat of dong tang chongming yangtze estuary was chosen as research object and two typical section plane was set up in order to measure four seasonal hydrology element and get index datum such as water level, current direction, current speed
得到如下結論： （ 1 ）以長江口崇明東灘敞開型潮灘為研究對象，設置了兩條代表性斷面，實測了四個季節的水文要素，獲得了包含水位、流向、流速等指標數據。 -
