To clarify the responses of stream habitat factors to riparian land use change,50reaches of 3typical streams in the suburb of Beijing City are selected for the discrepancy test and principal component analysisof habitat indicators under different riparian land uses.By factorial rotation,four integrated indicators areconfirmed to reflect the impacts of different riparian land uses on stream ecosystem,which are shown inplots.Results show that the land for tourism has greater effect on benthic macroinvertebrates species and theconcentration of phosphorus in stream than the land for transportation;the land for inhabitancy increases theconcentration of nitrogen in stream;and farmland affects phytoplankton species,pH value and the concentration of dissolved oxygen.Maintaining rational land use is a basic approach to stream ecological restoration inthe suburb of Beijing City.
