Landscape Design Of Hengtang Ecological Park In Suzhou City Based On The Concept Of Near Nature

Due to the expansion of modern cities,urban green space has been eroded,and the deterioration of green space environment has led to increasingly obvious ecological problems of air pollution and water pollution in urban environment.In 2018,the concept of "Park City" was put forward,advocating the improvement of urban ecological environment,meeting people’s needs for a beautiful living environment and promoting the construction of ecological civilization.Urban ecological park is one of the important carriers of urban ecological environment and an important way for urban people to feel the nature.Although urban ecological parks have certain ecological benefits,the traces of human intervention are obvious,and the ecological development law is often ignored in landscape construction.Applying the concept of "close to nature" can effectively alleviate the contradiction between "artificial" city and "natural" ecology,therefore,it has important practical significance for the construction of urban ecological park.From the perspective of close-to-nature concept,this subject uses literature retrieval,case analysis,field investigation,cross-research and other research methods to design and create the Hengtang Ecological Park in Suzhou.Through the research and analysis of the relevant theoretical and practical research status at home and abroad,the typical design cases are deeply analyzed,and it is clear that the landscape design of urban eco-parks under the guidance of the concept of near-nature should pay attention to restoring the landscape ecological environment,creating the natural habitat space,constructing the circular ecosystem,spreading the urban regional culture and stimulating the people’s participation vitality.Secondly,the concept of near-nature and the related concepts of urban ecological park are defined,and the relationship between them is analyzed,and the principles and methods of urban ecological park landscape design under the concept of near-nature are summarized,so as to provide theoretical guidance for practical research.Finally,in the concrete design practice,combining with the actual conditions such as site status and crowd demand,aiming at the problems of ecological environment destruction,serious waste pollution and hardening of land in Hengtang Post Island,plant landscape,water landscape and hard landscape are taken as the key points of "near-naturalization" of urban eco-parks,and the landscape space of urban eco-parks with diverse plant habitats,natural water habitats and ecological hard environments is constructed by means of near-natural design and transformation.Build an urban ecosystem with the function of self-succession and evolution,use natural forces to repair and improve the urban ecological park environment,and realize the design goal of harmonious coexistence between man and nature,and between city and nature.
