Planning And Design Of Songjiang Wetland In Harbin From The Perspective Of Ecological Restoration

Wetland is the highest primary productivity ecosystem in nature,also the most biodiversity site,providing multiple ecological services for cities.As an important part of Harbin ecosystem,Songjiang wetland not only has important ecological value,but also has important economic value and social value.In recent years,the process of urbanization in Harbin is in the stage of vigorous promotion.High-intensity human activities and disorderly development make the ecological resources of Songjiang wetland encroached year by year,the ecological environment of wetland is extremely deteriorating,and the ecological restoration of wetland is imminent.Under the scientific orientation and strategy,reasonable planning and design is the first way to protect and restore wetland resources.Taking Harbin section of Songjiang wetland as the research object,this paper analyzed the general situation and existing problems of wetlands in the study area through field investigation,literature research,theoretical reference and application,and comprehensive induction.Based on the theory of restoring ecology and landscape ecology,based on its natural and socio-economic conditions,aiming at its present situation and the problems such as the sharp decrease of wetland area,the damage of biodiversity,the lack of regional characteristics in landscape planning,and fully respecting the local ecological environment,this paper aims at restoring the comprehensive ecological service function of Songjiang wetland to the greatest extent,and seeks the ecological function restoration rules of Songjiang wetland.Design method.This paper summarizes the planning principles of Songjiang wetland from the perspective of wetland landscape elements and ecological restoration,and puts forward the concepts of compatibility,integration and infiltration: protection,restoration and development objectives;and transformation,control,softening,selection and provision strategies to rebuild the biological chain of Songjiang wetland and restore the ecosystem as far as possible.Finally,the scheme is optimized according to the recovery situation,and the feedback repair method is realized.Seeking the balance point among people,city and wetland will provide an opportunity for Harbin to restore the water ecology of Songhua River,integrate urban and rural areas,and adjust the economic structure of old industrial bases.
