Research On Priority Protection Bird Species Selection And Habitat Restoration In Tianjin Qilihai Wetland

Wetland ecosystem has become an important resting place,habitat and breeding site for birds due to its rich wetland resources and diversified ecological environment,which plays an important role in maintaining bird diversity level and improving species richness.In recent years,the change of wetland environment leads to the destruction of the habitat of wetland birds,which seriously affects the survival and reproduction of wetland birds.For birds,they are an indispensable part of wetland ecosystem and play an important role in maintaining the balance of wetland ecosystem.If the number of birds is reduced or even extinct,the wetland ecosystem will be seriously threatened.Such a vicious cycle is bound to lead to more extreme consequences.However,the traditional wetland landscape design and the constructed wetland design for the purpose of water purification pay little attention to the protection and restoration of biodiversity,and it is difficult to improve the current situation that the number of wetland birds and their habitats decreases sharply.In this context,according to the habitat demands of wetland birds,the targeted habitat restoration and construction has become an important problem to be solved urgently.Based on the above problems,this study took the concentrated distribution area(core area and buffer zone)of birds in the Qilihai Wetland in Tianjin as an example,combined with field research and analysis of existing data,and summarized the existing problems of bird habitat in this area.Then,the wetland bird species that need to be protected most in the Qilihai Wetland were selected by the ecological quantitative research method,which is the priority bird species in this study.According to the domestic and foreign literature on ecology,the habitat demands of the preferred bird species were analyzed and their habitat selection preference was determined.On this basis,this paper discusses how to carry out habitat restoration research in the concentrated distribution area(core area and buffer zone)of birds in the Qilihai Wetland,and discusses the appropriate strategies for bird habitat restoration in this area.This study provides a feasible method for restoring the habitat environment of birds in the region,maintaining the diversity level of wetland bird community and improving the stability of wetland ecosystem.At the same time,it provides reference for other similar wetland bird communities and their habitat environment protection and restoration.
