Study On Landscape Quality Evaluation And Optimization Strategy Of Recreation Space In Beijing Country Park

In order to protect the urban ecological environment and human settlements,Beijing has begun construction of green belts in rural areas very early.With the rapid development and expansion of the city,the function of the green isolation belt has changed from a single ecological protection role to a dual function that simultaneously provides recreational services.The construction of suburban recreational space is of great significance to the improvement of the urban green space structure and the protection of the urban ecological environment.The "Beijing Urban Master Plan(2016-2035)" clearly proposes to improve the green space structure of urban and rural areas,build a new country park ring,and existing country parks located in a green partition will change their positioning in the future.For this reason,the landscape quality of rural recreational space should be valued and guaranteed.Studying the quality of the existing rural recreational space is of great significance for the optimization of the existing space and the construction of new rural recreational space in the future.In this paper,first of all,the existing country parks in Beijing were investigated,and the spatial layout of the existing country parks was analyzed.Nine representative country parks were selected as the key research objects.Secondly,based on the current situation of country parks,by consulting the evaluation system information of landscape architecture and expert consultation,the paper establishes the evaluation system of recreation space landscape quality for country parks by using AHP,and establishes.The evaluation includes three objective layers: macro layer of location characteristics of recreation space,meso layer of recreation space recreation resource quality and micro one of landscape environment comfort.13 indicators were selected and weighed into different evaluation level based on its correlation with parks.Next,through multiple and detailed evaluation indicators and multiple technical methods,including network data collection,questionnaire,field surveys,instrument measurements,and data visualization via GIS platform.The evaluation content and result of each evaluating issue was gained.This result will be valued as score,which is helpful for intuitive judgment.Based on the research and analysis in the evaluation process and the results of the final evaluation,from the perspective of recreation space and various indicators,this research created an assessment outcome of advantages,disadvantages and corresponding optimization strategies of Beijing countryside park recreation space.Finally,several recommendations were offered.From the perspective of planning,it is suggested to improve quality management,strengthen planning equity and residents' needs awareness,and improve the advantages of space and resource utilization;from the design perspective,it is better to improve the design guidelines of the country park recreation space and involve a multi-period retrospective evaluation system;designers are encouraged to focus more on the current hot issues of public health and comfortable living environment,and use this as an entry point for landscape design transformation and improvement.At the same time,simulation verification via software should play an increasing role in design process,comparing the changes in thermal comfort before and after design and resulting in a new design transformation and evaluation methods,in order to ensure the effective optimization and improvement of the landscape quality of the country park recreation space.
