Study On Landscape Planning Of Wetland Park With The Overall Planning Of Xuncheng Wanling Lake Wetland Park As An Example

Wetlands are called"the kidney of the earth",and the forest,the ocean is tied to the three major global ecosystem types.In the flood control drainage,purification of water quality,biodiversity conservation and so has an important role.Urban wetland is an important part of urban ecosystem.In recent years,due to lack of attention and improper development,urban wetland ecosystem has suffered from damage,which directly threatens urban ecological security.The construction of urban wetland park not only plays an important role in wetland protection,but also is the effective way of rational and rational utilization of wetland,which is an ideal and effective mode for coordinating urban development and utilization of wetland resources.Xuancheng Wanling Lake Wetland is located in the southern Xuancheng urban area,is a typical middle and lower reaches of the Yangtze River freshwater lake wetlands,is also a typical urban wetlands.This paper summarizes the relevant theories of wetland park planning and the research progress at home and abroad,and takes Wanling Lake wetland as the research object to carry out investigation and analysis of wetland resources in Wanling Lake.According to the requirements of provincial wetland park construction and related technical regulations,Linghu wetland park construction master plan for the construction of Wanling Lake Wetland Park to provide a scientific basis.The main results are as follows:(1)Wanling Lake Wetland Park is located in the south of Xuancheng City,an area of about 267.4hm~2.It is a typical freshwater lake wetland and urban wetland in the middle and lower reaches of the Yangtze River.Wetland area of 163.0hm~2,accounting for 61.0%of the total area;covers an area of 104.4hm~2,accounting for 39.0%of the total area,in line with the total area of wetland park planning and wetland conditions.(2)Wetland Park is rich in biodiversity,there are more than ten kinds of fish,including economic fish,there are four major domestic fish and grass carp,carp and so on;dozens of birds,common Egret,pond heron,night heron,Mandarin ducks,cormorants,black water chicken,bone chicken,etc.;in addition to a variety of frogs and reptiles;major flora types include grass group,empty lotus seed group,reed group,Group,water Polygonum group,Fengye lotus group,Zizania caduciflora and so on.(3)The nature of the wetland park is the prerequisite of the protection and restoration of wetland resources,and give full play to the three basic functions of ecological protection,popular science education and eco-tourism of wetland parks,and protect the habitat of rare birds habitat,Typical wetland landscape,financial natural and cultural landscape as one,will be built for tourism,sports,leisure,science and education as one of the provincial wetland park.(4)Wetland Park is divided into wetland conservation area,restoration and reconstruction area,mission demonstration area,rational use area,management service area.The area and proportion of each partition were 18.35hm~2 and 6.86%,168.42hm~2 and62.98%,27.40hm~2 and 10.25%,42.40hm~2 and 15.86%,10.83hm~2 and 4.05%respectively.(5)put forward the wetland protection planning,restoration planning,popular science education planning,scientific research and monitoring planning,rational use of planning,disaster prevention planning 10 special planning program.
