Studies On Planting Design Of Wetland Park Surrounded By Chaohu In Hefei

Wetland Park is a special type of park based on wetland landscape,which has an irreplaceable role in ecological and social function.It can provides leisure and entertainment facilities and can carry out popular science education and culture in the park.wetland park have a lot of value,like biological diversity,ecology and aesthetics and other aspects.In this study,selected 13 wetlands and wetland parks as the research objects which surrounded by C haohu,and the knowledge of ecology,recreation and garden aesthetics were used to explore the planting design of Wetland Park Surrounded by Chaohu,by the methods of field researching,mapping and diagram analysis.The main results were bellow:(1)Plant composition and proportion of wetland park surrounded by Chaohu in hefeiThere are terrestrial,wet and aquatic plants in the wetland park which surrounded by Chaohu,The proportion of them is 52.7%,24.7% and 22.6%.Among them,the proportion of terrestrial plants is the largest,next is wet plants and the last is aquatic plants,and the proportion of wet plants and aquatic plants is close.Apart from this,the aquatic plants were divided into emergent aquatic plant,floating plant and submerged plant,the proportion of them is 62.3%,25.4%,12.3%.The dominant species is Phragmites australis?Potamogeton crispus?Potamogeton malaianus?Myriophyllum spicatum and so on.(2)Community structure of planting design of wetland park which surrounded by Chaohu in hefeiThe arrangement of planting design of wetland park can be divided into aquatic plant community landscape,inter-shore plant community landscape and terrestrial plant community landscape according to habitat type.Aquatic plant community landscape configuration in three ways,the first,to use Phragmites australis,Arundo donax var.donax as the main community,supplemented by Typha orientalis,Zizania latifolia,Triarrhena sacchariflora and so on to create a natural state under the water features;the second,to use Salix babylonica,Thalia dealbata,Nelumbo lutea,Typha orientalis and so on as the main community,supplemented by Myriophyllum verticillatum,Nymphaea tetragona Georgi,Eichhornia crassipes to create a viewing-based water features;the third,to use Populus,Metasequoia glyptostroboides,pinus elliottii as the main commun ity,supplemented by Sagittaria trifolia var.sinensis,Lythrum salicaria,Ceratophyllum demersum and other plants combined with the water to create a hazy landscape.There are three landscape configurations for the shore plant community,the first,to use Cinnamomum camphora,Pterocarya stenoptera,Nerium indicum as the main community,supplemented by Symplocos caudata,Photinia serrulata,Humulus scandens to create a natural reflection of the landscape;The second to use Magnolia grandiflora,Osmanthus fragrans,Ligustrum quihoui as the main community,supplemented by Rosa multiflora,Chrysanthemum indicum,Kalimeris indica,to create both the viewing and resting landscape.There are three landscape configurations for terrestrial plant communities,the first to use Celtis sinensis,Salix matsudana,Magnolia denudata,Lagerstroemia indica as the main community,supplemented by Camellia sinensis,Lonicera japonica,Euonymus japonicus,to create a wetland park in the important landscape node;The second use of lonely way to use Bischofia polycarpa,Cinnamomum camphora,Osmanthus fragrans as the main community,supplemented by Bougainvillea spectabilis,Jasminum sambac,Loropetalum chinense var.rubrum,Zoysia matrella,etc.to create a large area of sparse forest lawn landscape;the third,to use Taxodium distichum,Metasequoia glyptostroboides,as the main community,supp lemented by Fatsia japonica,Farfugium japonicum,Ophiopogon japonicus to create a gentle slope of plant landscape.(3)The construction techniques of planting design wetland park which surrounded by ChaohuFrom the creation of natural landscape,into the modern plant landscape design concept and highlight the characteristics of the landscape starting three points,put forward the first through the use of three kinds of traditional water management techniques,the combination of plants and water to form a better wetland plant landscape effect;The second use of gentle slope bank,plant slope protection,auxiliary measures to protect the three forms of natural ecological shore,to create the inter-shore plant landscape;third to create a characteristic flower landscape,the establishment of a variety of special garden,and the introduction of bamboo and other new plants To create the characteristics of the Central Chaohu Lake C ity Park landscape.
