Water regimen monitoring and analyzing system and method facing ecological water demands of river-communicating lakes

Abstract

The invention discloses a water regimen monitoring and analyzing system and method facing ecological water demands of river-communicating lakes. The system comprises a water demand calculation module, a real-time monitoring module, an analysis and comparing module and a display output module, which are connected with a control maintenance module respectively, wherein the water demand calculation module comprises a lake region ecological water demand calculation unit, a lake-exiting ecological water demand calculation unit and a lake-entering ecological water demand calculation unit; the real-time monitoring module comprises a lake-exiting flow monitoring unit, a lake-entering flow monitoring unit and a lake region state monitoring unit; the analysis and comparing module is used for receiving data from the real-time monitoring module and the water demand calculation module and performing analyzing and comparing; the display output module is used for representing the data obtained by the analysis and comparing module, and extracting and outputting. By adopting the water regimen monitoring and analyzing system and method, the real-time monitoring problem of an ecological water demand meeting condition of the river-communicating lakes is solved, and a lake region ecological water demand meeting rate, a lake-exiting ecological water demand meeting rate and a lake-entering ecological water demand meeting rate of the lakes can be measured respectively and are visually and dynamically displayed.

Description

technical field [0001] The invention relates to the technical field of water conservancy engineering and water resource protection, and in particular to a water regime monitoring and analysis system and method for ecological water demand of lakes connected to rivers. Background technique [0002] The ecosystem is the basic natural condition for human survival and development, and water is one of the controlling factors for maintaining the ecosystem. However, for a long time, human development and utilization of water resources were mainly oriented towards the development of human society and economy, ignoring the needs of the ecological environment. The construction and development of water conservancy projects provide an important guarantee for the social economy, but the resulting changes in the quantity and state of water resources in rivers and lakes also have a certain impact on the ecosystems of rivers and lakes. The rational development and utilization of water resou...
