dc.description.abstract象山港是宁波市重要的港口,位于东经121°25′~122°03′,北纬29°24′~29°48′,港区总面积563.3km2,海域面积391.76km2,滩涂面积171.53km2。港内生境类型多样性高,物种丰富。近年来象山港海水养殖、过度捕捞和临港工业带来的环境影响越来越明显,水质参数(总氮TN,氨态氮NH3-N,磷酸盐PO4-P,氮磷比N/P)均超IV类海水水质标准,富营养化严重。因此通过建设海洋牧场来改善生态环境,恢复渔业资源显得非常必要。本研究应用稳定同位素技术研究了象山港海洋牧场食物网的营养基础和结构,并利用EcopathwithEcosim6.0(EwE)构建了象山港的能流模型,对...
