| 主要内容：The coastal ecosystem health assessment is a field of increasing importance.In this paper,a preliminary assessment of ecosystem health in Zhejiang cosatal water zone was made,mainly based on remote sensing data and GIS technique.Its spatial and quantitative evaluation was facilitated by the prorgess of remote sensing and GIS technique development.Firstly,human activities,hydrology and ecosystem problems in the study area were discussed andanalyzed.Secondly,from 4 aspects of human stress,physical,chemical and biological responses to anthropogenic cativities and natural stress,several indicators such as water transpraency(Secchi Disk Depth,SDD),suspended substance concentration,dissolved inorganic nitrogen,active phosphate,chlorophyll,harmful algae bloom,as well as distribution of sewage,sea lanes and port were employed.Thirdly,the Analytic Hierrachical Process was used for indicator weight calculation,..... |
