Henan Water Conservancy Survey., LTD, China
From 09/2012 to 07/2013, Study on the Construction of Ecological Water System and Water Resources Optimization Dispatching in Zhengzhou City
The research object of the project is Zhengzhou City's ecological water system, which is connected by rivers, reservoirs and lakes within the urban area and surrounding areas, and constructs the ecological water system pattern of “six vertical and six horizontal river canals, seven medium and five small reservoirs, three lakes and two wetlands”. To achieve comprehensive utilization functions such as flood control, water supply, ecology, landscape, and tourism.
From 09/2013 to 07/2014, Research on Water Resources Protection and River and Lake Health Protection Law System
Through analysis and study of the characteristics and experiences of water resources protection legislation in various countries, the project improves and promotes the construction of China's water resources protection and river and lake health security system.
From 09/2015 to 10/2018, Research on the mechanism of drought and flood occurrence and disaster reduction methods (51339004)
The project takes the alternating process of drought and flood as the research object, and analyzes the influence mechanism of drought and flood alternation stress on crop water physiology and final yield formation, and studies the infiltration and non-water accumulation in the process of drought and flood. The hydrological model of irrigation district under the condition of alternating seepage and changing water flow direction establishes a nonlinear dynamic statistical drought and flood disaster prediction model with weather climatological significance and dynamic mechanism, and predicts the long-term change of drought and flood in different climate scenarios in the future.
