Zusammenfassung: | The invention discloses a composite erosion protection method for an ecosystem in a fragile area, and relates to the technical field of environmental governance, and the method takes surface water as surface runoff and interflow of a hydrological response unit and base flow generated by shallow underground water of a sub-basin. In the model simulation process, surface runoff of the hydrological response unit firstly passes through the sub-river channel process to generate transmission loss, environmental parameters of a target area are obtained through a parameter transplantation method, local surface runoff, daily rainfall, rainfall initial loss, drainage basin possible maximum retention volume and a runoff curve coefficient are obtained, and then a target value is obtained through formula calculation. The obtained result is fast and accurate, and the defect that model demonstration cannot be carried out in current environmental governance is overcome.
