摘　　要：以1985年、1995年、2005年及2014年的TM遥感影像及近年来的海洋环境质量监测数据为依据,分析了人类活动影响下象山港潮汐汊道及其沿岸生态系统演化的特征.结果表明：（1）1985~2014年,研究区耕地、海域、滩涂、湖泊河流以及林地等生态系统类型面积呈下降态势,建设用地、未利用地以及养殖用地与盐田等面积呈增加态势;（2）临海工业的快速发展使象山港海域水体DIN和DIP超标严重,以Ⅳ类和超Ⅳ类水质为主;（3）受人类活动的影响,象山港潮汐汊道海域生物量减少、栖息密度下降;（4）象山港潮汐汊道及其沿岸生态系统服务功能明显减弱.Based on the information of TM remote sensing image of 1985, 1995, 2005 and 2014, as well as the marine environmental quality monitoring data in recent years, the features of the ecological system evolution of tidal inlet and its coastal area of Xiangshangang Bay are analyzed under the influence of human activities. It is found that： （1） From 1985 to 2014, the arable land, sea area, beaches, lakes and rivers, and forest take on a downward trend while the area of the construction land, unused land, farming land and salt field tend to have an increasing momentum; （2） The rapid development of the coastal industries of Xiangshangang Bay makes DIN and DIP of water exceed the standard, especially the water quality of IV class and super-class IV; （3） Affected by human activity disturbance, the oceanic biomass and inhabit density of tidal inlet of Xiangshangang Bay show an obvious decline; （4） Ecosystem services of tidal inlet and its coastal area of Xiangshangang Bay have been damaged at an alarming level.
