Remote sensing technology, geospatial analysis and statistical analysis were integrated to link land use and water quality in four river basins of Beijing. Results showed that Beijing was in a rapid urbanization process from 1989 to 2008. At buffer zone scale, area of built-up area and transportation land were positively correlated with TN and NO3−-N, and negatively correlated with TP and NH4+-N;...
