Relationships between land use pattern and surface water quality in Beijing

摘要

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; Agriculture land was strongly related to TP, while negatively related to NO₃--N; other land use types were not good predictors for water quality in the study area.
