Research On The Design Strategy Of River Wetland Park Base On The Close-to-nature Concept

With the rapid expansion of cities,the impact of human activities on rivers is increasing.The ecosystems of many river have been disturbed,and wetland landscapes are gradually disappearing,leading to serious constrains on social development.How to build a river landscape more in line with the natural ecological laws,to meet the public’s recreational needs while maintaining the balance of the wetland ecosystem,is the key research content in the current and future river landscape construction.The paper conducts an in-depth study on the concept,theoretical basis and research status of the close-to-nature concept and the concept,type,structure,function and research status of river wetland parks through literature research,case study,induction and summary,field research and design practice.From the ecological point of view,a complete set of design strategies from hydrological and geomorphological combing,plant community restoration,biological habitat improvement,to landscape space integration is sorted out,and the design of river wetland park under the close-to-nature concept is scientifically and completely discussed and applied to the design of Yongding River Machang Wetland Park.The close-to-nature concept is based on ecological thinking,relying on the natural characteristics and natural processes of the ecosystem to achieve the common goal of economic development and ecological protection.to achieve the effect of low-cost,close-to-nature,ecological and recreational balance.In the context of river ecological landscape construction,it is a good fit for the current construction requirements of river wetland parks.The research on the design strategy of river wetland park based on the concept of close-to-nature can further enrich and improve the theoretical ideas of river ecology and landscape design,provide reference for the future practice of river wetland park,meet the ecological environment and human society needs,and promote the progress of people’s cognition of river wetland.
