Research On Landscape Planning And Design Of The Riverside Wetland In The Middle Section Of The Hutuo River In Shijiazhuang

With the development of industrialization and urbanization,the water quality of wetlands has decreased,and the wetland environment has been damaged.The irrational use of wetland space leads to a decrease in the wetland area,which leads to a decrease in urban flood-carrying capacity,and thus affects the quality of people’s life and urban ecological security.A series of issues highlight the necessity and urgency of rational planning and utilization of wetland landscape space.As a living space for hundreds of millions of people,the construction of wetlands should also meet the people’s yearning for nature,strengthen humanistic care,and pay attention to the construction of ecological functions.At the same time,it should also pay attention to the construction of infrastructure to enhance the interaction between people and nature.Riverside wetland landscape is an important part of the urban river landscape,which combines meeting the interactive needs of the public and nature,mitigating urban rain and flood disasters,and achieving the harmonious development of the public,city,and nature.The exploration of a riverside wetland landscape in this article is mainly divided into the following four aspects.Firstly,through literature analysis,the research progress of wetlands and wetland landscape at home and abroad was analyzed from both theoretical and practical aspects;The concepts related to wetlands,wetland landscapes,and riverside wetland landscapes were analyzed;Research on water cycle theory,landscape ecology theory,elastic landscape theory,and sponge city theory to provide theoretical reference for planning and design.Secondly,data collection and on-site research were conducted on excellent cases both domestically and internationally,including the Qinjiang River Old River Wetland Landscape,Fenghe River(Cultural and Educational Park Section)Riverside Wetland Landscape,Dianchi Lake Laoyu River Wetland Landscape,Singapore Sungei Buloh Wetland,and Thames River Wetland Center.Analyze the project overview,characteristics,and references of each case,and summarize the design strategies for each case.Then,based on the current situation of the site,an evaluation of the suitability of the riverside wetland landscape is constructed,and a design strategy for the Hutuo River riverside wetland landscape in Shijiazhuang is proposed.Select evaluation factors for grading and quantitative analysis.Specific single factors include elevation,slope,slope aspect,land use,vegetation coverage,and water buffer distance.The suitability evaluation process of the Hutuo River riparian wetland includes: obtaining basic site information through DEM data,remote sensing images,and current status photos of the base;Using Arc Map and ENVI software to process information to obtain single factor classification and quantitative analysis;Then use the analytic hierarchy process in SPSSAU 18.0 software to determine the weight value of each factor;Import the weight values of each factor into Arc Map to obtain a comprehensive analysis of the suitability evaluation of the Hutuo Wetland.The analysis results are divided into three aspects: suitable,relatively suitable,and unsuitable.Based on the analysis results,propose reasonable planning strategies for the base site.Finally,based on the previous theoretical analysis and strategic research,the planning and design of the wetland landscape along the Hutuo River in Shijiazhuang were carried out.Analyze the project background and overview,combine the surrounding and internal status of Hutuo Wetland,clarify the design objectives and positioning,and carry out planning and design on the premise of following the design principles.The overall planning is to form a landscape structure of "one pulse,two rings,three clusters,and multiple points",forming six major landscape zones: leisure and health area,shade treatment area,wetland roaming area,wetland science popularization area,cultural exhibition area,and hilly forest viewing area.Design major scenic spots such as the main entrance square,water walking,wetland plant science park,and tea aroma around the water,and make special plans for the vertical planning of the site,road traffic,water system,riverside wetland habitat,plant landscape,experience activities,service facilities,and lighting system.Build the wetland landscape along the Hutuo River in Shijiazhuang into a place that integrates leisure and recreation,popular science education,ecological sightseeing,and health care.
