Study On The Design Of Xinghua Dazong Lake Wetland Ecological Scenic Spot Under The Thinking Of "Ecological Acupuncture"

Wetland ecological scenic spot refers to the ecological scenic spot established mainly by the wetland environment composed of aquatic and terrestrial animals and plants.It has the advantages of high vegetation coverage,rich ecological resources and good ecological benefits.They have different types and have their own characteristics in topography,resources and climate.Now in China,on the one hand,the number of ecological scenic spots in China has been almost saturated,thus entering the "stock era".On the other hand,a considerable number of wetlands are facing a similar situation to Dazong Lake Wetland: large-scale reclamation,resulting in the destruction of the surrounding ecosystem.However,there is no theoretical model for the transformation of such rural Lake type wetland with farmland.Facing the above background,there is an urgent need for a more effective,economical and diversified landscape approach to solve the current design problem of "less harm" but can bring short-term returns."Ecological acupuncture" is a design method of restoration,restoration and regeneration to seek the connection between man-made system and natural system.Based on this theory,combined with relevant design cases at home and abroad and relevant theories such as "urban acupuncture","micro ecological landscape" and "urban micro renewal",this paper will summarize a set of planning and design strategies for Lake suburban wetland ecological scenic spot,namely: diagnosis of the crux-preliminary analysis,sorting out the context-Road streamline,dredging acupoints-integrated design,and finally point acupuncture-landscape element design,The strategy is applied to Xinghua Dazong Lake wetland ecological scenic spot.Xinghua Dazong Lake wetland ecological scenic spot is located in the water Township of the central Jiangsu Plain.Before the transformation design,the author makes a detailed and in-depth investigation on the local natural geography,climatic conditions and hydrological characteristics,natural ecological resources,cultural ecology and social ecology of Xinghua.After clarifying the ecological matrix,patches and corridors of the site and the local policies and regulations on wetland governance,the overall design vision is no longer the wetland landscape of the "less harm" reserved site,but follows the natural rhythm and pattern in the design,restores and regenerates the wetland with small-scale transformation,and deeply excavates the regional culture from the natural background.Therefore,the overall planning of the base is "one belt,three areas and five centers",that is,one belt: the main ecological corridor of the site.Three zones: buffer zone,protection zone and activity zone.Five hearts: Folk ecological experience area,leisure resort,ecological health care area,ecological science popularization area and ecological conservation area.In addition,the "ecological acupuncture" method is used again to carry out "acupuncture" transformation in some areas with more damage,so as to strengthen the conservation and storage function of wetlands,such as soil transformation,wetland reservoirs and ecological floating islands.After this study,the author will explore a set of reference models for landscape optimization design in wetland ecological scenic spots or similar aspects.
