Research On The Evaluation Index System Of Urban Green Open Space Under The Guidance Of Health

With the continuous advancement of social progress and urbanization,the green,healthy and high-quality development of urban living environment has been highly valued.The material spatial form of green open spaces has an important impact on public health.Currently,most of the existing research focuses on the fields of medicine and hygiene,and there is still a gap in research focusing on residents’ spatial use dimensions.Meanwhile,the research on the quantitative evaluation system of green open spaces is also insufficient,to the extent that the health service level of urban green open spaces is still unclear.Therefore,constructing a suitable evaluation index system for the health impact level of urban green open spaces can help improve the assessment tools for healthy cities,and provide reference for promoting the planning,construction,and management of urban green open spaces in China.This research aims to promote the physiological,psychological,and social health dimensions of the human body.Through analyzing keywords such as healthy cities and green open spaces,as well as a review of relevant research and the constituent elements of urban green open spaces,and their impact process and mechanism on human health.A mechanism model of the impact of urban green open space on human health has been constructed,and the three elements of healthy space,healthy use,and healthy culture have been extracted.Based on the perspective of residents’ use,the factors with potential to promote human health and the necessary conditions for their effectiveness were analyzed.Referring to research on relevant indicator systems at home and abroad,an evaluation index system for health oriented urban green open space was constructed using expert consultation method.The weights and target values of each level of indicators were determined using Analytic Hierarchy Process,and a fuzzy comprehensive evaluation model was established.Using the constructed evaluation model,typical examples of point,linear,and planar green open spaces within the main urban area of Kunming City were selected for evaluation and analysis.The feasibility of the evaluation index system constructed in this research was verified,and the health impact level of green open spaces in various dimensions in the main urban area of Kunming City was measured.Based on the analysis and extraction of the constraints of green open spaces on public health development,as well as the fuzzy comprehensive evaluation results of various levels of indicators,this research proposes corresponding optimization strategies and suggestions,in order to provide reference for the optimization design of future urban green open spaces.
