Study On Evaluation And Optimization Of Plant Landscape In Shenyang Olympic Park Based On AHP

With the rapid development of the city and the accelerated pace of daily life,the residents of the city are increasingly looking forward to the holidays and evenings to the nearby natural parks or scenic spots.The landscape ecology of urban waterfront plays an important role in urban environmental quality and urban landscape.The scientific nature of plant landscape design can not only improve the environmental quality,but also increase the ecological benefits of green space.Plants,as an important component of the park's soft landscape,are closely related to people's lives.Their configuration level and landscape evaluation methods are also important research knowledge.Therefore,it is necessary to study how the park landscape can be optimized through sustainable development.This study takes the plant landscape of Shenyang Olympic Park as the research object.The main area of research is the Hun River South Bank Olympic Park between Shenyang Hun Bridge and Fumin Bridge.This paper attempts to use AHP analytic hierarchy process to systematically study the comprehensive evaluation and optimization of plant landscape in Waterfront Park.The significance of this topic is to provide reference and reference for the improvement and optimization of plant landscape in urban parks.The park plant landscape was optimized through the establishment and evaluation of the Olympic Park plant landscape evaluation system.The main research contents are:on the basis of on-the-spot investigation,the statistics of all the arbor layer and shrub layer plants in Shenyang Olympic Park are analyzed,and the dominant species and species composition ratio are analyzed.According to the proportion and topography of the Olympic Park green space plant community type,select 12 The typical plant communities of different vegetation types were analyzed by plant community research methods,such as the species composition of the plot,the quantitative characteristics of the plants,and the species diversity.From the perspective of plant community and aesthetics,comprehensive analysis The specific configuration characteristics of the type-like plants;the AHP method was used to evaluate the plant landscape of the Shenyang Olympic Park.In the evaluation model,the qualitative evaluation combined with the quantitative evaluation,the quantitative indicators from the species diversity,plant ornamental characteristics diversity,life There are five indicators of type structure diversity,plant landscape time series diversity and plant space level diversity.The qualitative indicators consist of three indicators:the coordination of plants and the overall environment,the harmony with the hard landscape,and the harmony of habitats.The five quantitative indicators were calculated by the Simpson index formula,and the plant community landscape of Shenyang Olympic Park was comprehensively evaluated in combination with the evaluation scores and weights of qualitative indicators.The comprehensive evaluation scores of 12 plots of plant community landscape were obtained.The purpose was to explore the problems of plant community landscape construction in the Olympic Park,and use this as a basis to optimize and enhance the corresponding suggestions and strategies of the park.Finally,based on the preliminary exploration and research on the theory of plant landscape optimization,the theory is transformed into reality,and the specific optimization scheme design of the Olympic Park plant landscape is carried out from the perspective of the whole and individual cases.The research and exploration of the optimization of the plant landscape of the Olympic Park can also provide reference for the optimization of the plant landscape of other urban riverside comprehensive parks.
