| 英文摘要 | By converting rural land into urban land, urbanization impacts on surface water quality, because cities produce more pollutants than farmlands, especially heavy metals. ways to reduce urbanization impacts on water quality are now being highlighted worldwide. considering that land use can be a source or sink in pollution runoff, an understanding of the relationship between urbanization and surface water quality, as well as effects of specific land uses on water quality, is crucial. corresponding management and controlling steps can then be put forward towards non-point source (nps) pollution control and urban sustainable development. china has experienced rapid urbanization, especially since the 1980s. however, the environmental impacts of this process are not fully investigated. hanyang, hubei province was selected as a typical city to study the impacts of urbanization on lake water quality. pearson's correlation analysis was performed to elucidate the correlation between different land uses and water quality indicators at both whole lake watershed and small catchment scales. the results indicated that land uses play different roles, either source or sink, in pollution flow processes. bottomland had a negative and residential land a positive correlation to most water quality indicators, especially heavy metals. these proved to be indicative and crucial land uses in nps pollution control. finally, a strategy for regulating urban land uses is proposed for improving surface water quality in cities similar to hanyang, in southern china. |
