Research Of Planning And Design Of Country Park Based On Ecological Performance Evaluation

China is in an important period of ecological civilization construction and ecological environment protection.For the development of the city,a good ecological environment is not only the most fair and beneficial social site,but also the important foundation of scientific and sustainable development.All kinds of green space in the city play an inestimable role in the regulation and improvement of urban ecological environment problems.It has significant ecological performance in soil restoration and protection,water conservation,air purification,carbon and oxygen balance,etc.How to evaluate the ecological performance of the green space in the city scientifically and take it as the important basis and scientific guidance of the green space planning and design,so as to promote the ecological performance of the green space in the city,maintain the ecological balance of the city and provide a healthy and sustainable ecological environment for the people is the current research focus of landscape architecture.Through the intervention of ecological performance evaluation,this paper discusses the planning and design of country park as the starting point,and discusses the guidance mode and function of ecological performance evaluation on urban green space planning and design.On the theoretical level,based on the relevant theories of ecological performance and the research progress at home and abroad,this paper summarizes the evaluation system and existing research results of ecological performance at home and abroad.Moreover,the concept,relevant theories and development and construction processof the country park at home and abroad are combed,the concept,function and planning and design principles of the country park are clarified,and the comparative study and reference are made based on the relevant ecological performance evaluation and the country park planning and design cases.Finally,according to the orientation of country park in the city and the goal of planning and design,the paper selects the ecological performance evaluation index suitable for country park in China and establishes the corresponding evaluation system,and discusses how to provide new direction and more scientific and sustainable technical guidance for the planning and design of country park in China through the intervention of ecological performance evaluation.At the practical application level,taking Nanshan country park in Beijing as an example,combining with the current situation of the site topography,vegetation planting,land use,etc.,and based on the principles of scientificity,operability,combined with the actual situation and demand of the project site,the ecological performance evaluation system is constructed from four aspects of soil,water,habitat,carbon,energy and air,and the ecological performance evaluation system is discussed The intervention of price system provides a new direction and method for the planning and design of country park.
