Study and evaluation on water environment quality of scallops culture area of Sishili Bay in Yantai
摘要
Abstract
According to the environmental detection of the scallops culture area at Sishili Bay of Yantai in 2016 from April to November,the basic physical and chemical indexes and the change trend of the sea in Sishili Bay were analyzed.The assessment of organic pollution index(A),nutritional index(E),seawater nutrient quality index(NQI)and Nemerow comprehensive evaluation of environmental quality index were used to evaluate the water environment quality in Sishili Bay.The results showed that:the sea water temperature,pH as well as salinity in Sishili Bay were suitable for scallops culture and the range of variation of which were 10.06~20.00℃,7.85~8.25 and 29.61~30.31,respectively;the dissolved oxygen(DO),pH,chemical oxygen demand(COD)and sulfide were in accordance with the first or second category of national quality standards,the total inorganic phosphorus(DIP)at some scallops culture areas exceeded the second category standards of national quality in October,total inorganic nitrogen(DIN)at some scallops culture areas exceeded the second category standards of national quality in April and October;The environmental quality was good from May to July,and the other months are subjected to varying degrees of organic pollution and eutrophication.Overall,the Sishili Bay scallops culture areas were in line with the first or second classes of requirements of scallops culture area,but we should pay attention to the protection of scallops culture area,especially the control of land sourced pollutants input.关键词
