Abstract
Urban wetland is the important part in urban eco-system, whose judge standard is eutrophication assessment. A comparative method of urban wetland eutrophication assessment was undertaken in Songbei wetlands to study the spatial distribution of eutrophication conditions in urban wetland environments. A modified trophic state index (TLI) consisting of six physical, chemical and biological indicators including total phosphorus (TP), total nitrogen (TN), chlorophyll-a concentration (chl-a), chemical oxygen demand (CODmn), biological oxygen demand (BOD5) and ammonia-nitrogen (NH3-N) was constructed to describe the eutrophication state of the wetland environment. A 0.100 eutrophication scale was also developed to indicate seven different trophic levels within the wetland environment: oligotrophic, lower-mesotrophic, mesotrophic, upper-mesotrophic, eutrophic, hypereutrophic and extremely hypereutrophic. Rank of eutrophication result from scoring method and corresponding weighted eutrophication indexes model (CWEIM) which implies water in Songbei wetlands is deteriorating, no matter what difference between the two methods.
