A method for ecological space optimization and function improvement of river wetlands

Abstract

The invention provides a method for optimizing ecological space and improving functions of river wetlands, and belongs to the technical field of river management. Determine and analyze the spatial structure of the current river, and obtain the area ratio of different river structures; determine the flow capacity of the river, and analyze the flood discharge capacity of the current river; And the flooding time and depth of the beach as the calculation basis, using the dichotomy method to analyze, respectively determine the excavation position of the river, the depth of the excavation, the vertical dredging space and the dredging volume, and optimize the wetland of the river beach; respectively analyze the spatial structure of the river before and after optimization Area, proportion and ecological space change amount, and evaluate the ecological space optimization scheme of the river course. Based on the comprehensive consideration of the structure and function of the river system, the present invention optimizes and manages the section of the river, realizes the improvement of the ecological function of the river and the optimization of the environment, and provides reference for the restoration, protection and function improvement of river wetlands in my country, as well as regional flood control and disaster reduction.

Description

technical field [0001] The invention belongs to the technical field of river management, and in particular relates to a method for optimizing ecological space and improving functions of river wetlands. Background technique [0002] The river wetland system is an open system in which the natural structure, ecological environment and economic society are coupled with each other. With the development of the economic society, the functions of the river are diversified, including water conservancy function, shipping function, ecological function, historical and cultural function, sewage function, The role of landscape functions is particularly prominent. The function of the river wetland system is determined by its structure, and the components of each structure interact and operate in coordination to realize various functions of the river. With the intensification of human activities and the development and progress of society, the degree of stress on water resources has intens...

Problems solved by technology

With the intensification of human activities and the development and progress of society, the degree of stress on water resources has intensified, the cross-section of the river has been continuously reduced, the flood discharge capacity has been reduced, the ecological space of the river has been occupied, the ecological function has been seriously degraded, and water environment pollution has become increasingly prominent, resulting in The ecological benefits of river wetlands are difficult to fully exert
