Abstract In order to solve water pollution problems in high-speed urbanized area of Dongjiang watershed, and to ensure the sustainable socio-economic development, comprehensive analysis of long-term deterioration of water environment caused by environmental, economic and social factors was conducted in Longgang district, Shenzhen Province. Then, specific programs were developed for industrial layout optimization, industrial structures adjustment, pollution control project and environmental capacity improvement. In addition, an integrated strategy was proposed for the system control of water pollution in rapid urbanization region. Results showed that the organic and nutrient pollution fluxes were increased yearly. Additionally, the water environmental risk and trace contaminants should be taken into account. The average ratio of pollution flux/river flow of were reduced by 40% in medium-term and 50% in long-term, compared with that before the implementation of the integrated strategy.
