Abstract: The Shenzhen River catchment has undergone fast economic growth and rapid population expansion coupled with water shortage and water quality deterioration. In this paper, a coupled system dynamic and river water quality model (SD-WQM) was used to account for the interactions among socio-economy, water resources, wastewater treatment as well as water quality in the catchment. The effects and sensitivities of structure of different industries on water environment improvement in the catchment were simulated. The results indicated that: a) industrial structure adjustment may alleviate water resource shortage but has little effect on water quality improvement; b) decreasing proportion of labour-intensive secondary industry or improving technology in labour-intensive secondary industry and tertiary industry have great effect on both water resource balance and water quality improvement. An integrated measure was also proposed to harmonize the socio-economy and eco-environment development in the catchment.
