River-lake communication method for guaranteeing multiple functions of urban rivers and lakes through water level control

Abstract

The invention discloses a river-lake communication method for guaranteeing multiple functions of urban rivers and lakes through water level control. The river-lake communication method comprises the following steps of setting a river-lake communication channel, setting an urban lake daily landscape water level and dead water level, and setting an urban main inland river daily landscape water level and flood control and drainage low water level; and the water level difference between the urban inland river and the lake is controlled to be adjusted to achieve flexible flowing of water between the urban inland river and the lake. In daily or dry seasons, the polluted water and pollutants in the urban inland rivers are effectively prevented from entering the urban lakes, the water quality safety of the urban lakes is guaranteed, meanwhile, the normal pollutant containing and discharging functions of the urban inland rivers are guaranteed, the urban inland rivers are replenished with the water through the water resource effect of the urban lakes, the power of river water in a city is effectively improved, the water ecological environment condition of the river water is improved, lake water is synchronously driven to flow, in the rainstorm flood period, the stagnant flood storage function of the urban lakes is effectively played, and the flood prevention and drainage defense capacity of cities is enhanced.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a method for connecting rivers and lakes to ensure the multi-function of urban rivers and lakes through water level control. Background technique [0002] Inland rivers are urban ecological corridors, as well as important sewage and flood control channels for cities. Due to the rapid development of cities and intense human intervention, problems such as "smelly ditch" and "black and odorous water bodies" commonly exist in urban inland rivers. Lakes are the eyes of the city and play an important role in tourism, leisure and entertainment, flood control and drainage, and improvement of urban quality and ecological environment. In order to realize the urban lake landscape and the hydrophilic function of leisure and entertainment, the water quality of lake water often has higher requirements. [0003] Connecting urban inland rivers and lakes is cond...

Problems solved by technology

[0009] ② The complete isolation of urban inland rivers and lakes is not conducive to play the role of lakes in flood storage and regulation during heavy rain and flood periods, which in turn affects the safety of urban flood control and drainage
