Abstract

In order to clarify the spatiotemporal variation patterns of water quality in urban river lake connected areas and improve the regional water environment, this research takes “Shanghai Fish” Lake and its surrounding backbone river network as the research objects. One-dimensional and two-dimensional hydrodynamic water quality model are both used to simulate the regional water quality, turbidity, and water exchange rate of “Shanghai Fish” Lake under three types of improvement facilities: no control, semi control, and full control. The results show that: (1) If no control measures are established, the water quality in the lake will be basically consistent with the peripheral river network, and the total phosphorus, total nitrogen, and turbidity will exceed the standard strictly; (2) If partial controlled, the connection between the lake’s water body and the peripheral river network can be appropriately delayed, and the water quality is basically uncontrollable; (3) If fully controlled, it can effectively delay the connection between the lake’s water and the peripheral river network, and the water quality can be basically controlled; (4) The construction and control method of building navigation lock combined with overflow weirs can meet the needs of flood control, ecology, and navigation.
