%X Urban non-point source pollution is a new problem appeared with the speeding development of urbanization.The particularity of urban land use and the increase of impervious surface area make urban non-point source pollution differ from agricultural non-point source pollution,and more difficult to control.Best Management Practices (BMPs) are the effective practices commonly applied in controlling urban non-point source pollution,mainly adopting local repairing practices to control the pollutants in surface runoff.Because of the close relationship between urban land use patterns and non-point source pollution,it would be rational to combine the landscape ecological planning with local BMPs to control the urban non-point source pollution,which needs,firstly,analyzing and evaluating the influence of landscape structure on water-bodies,pollution sources and pollutant removal processes to define the relationships between landscape spatial pattern and non-point source pollution and to decide the key polluted fields,and secondly,adjusting inherent landscape structures or/and joining new landscape factors to form new landscape pattern,and combining landscape planning and management through applying BMPs into planning to improve urban landscape heterogeneity and to control urban non-point source pollution.
