Effect Mechanism And Spatial Optimization Of Community Park Restoration Environment

Accelerating the pace of modern urban life,increasing competition pressure,lacking lifestyle of physical activity,especially the modern city life away from the natural environment,are caused by mental illness and chronic diseases some important factors.These health problems,which plague the modern urban population,are gradually widening and,if they can not be effectively prevented and controlled,they will seriously threaten human survival in the near future.Modern urban population is in urgent need of living space and places to Relieve mental stress,and to enhance the level of physical activity.Studies in Environmental Psychology have revealed that if the environment has certain positive characteristics,individuals in it would gain good restorative experience.It helps people to reduce the pressure and associated with the various negative emotions,reduce mental fatigue,promote mental and physical health.A large number of foreign research around the natural environment of the population health impact started,and the natural environment as the main city park is the urban population and the natural environment in contact with the most direct and effective place.In China's current urban green space classification standard,community park is a kind of important park green space for people's recreation.As one of the most direct places for people living in the city to be close to nature,they can greatly satisfy the physiological needs of people close to natural and psychological needs.This study first proposed the concept of community park restoration environment,and established park environment spatial optimization model based on residents' health recovery.Based on the concept of "restorative environment" and its related theoretical basis,this paper explores the impact mechanism of community park restoration environment,and establishes the theoretical framework including the optimization principle,optimization strategy and optimization model of community park restoration environment.It is of great practical significance to explore the new ideas and methods for the study of community park environment,to improve the quality of human settlements,to optimize the quality of life of urban residents and to improve the health restoration effect of community park environment.In the construction of the framework of the study,the impact of the mechanism of the retrospective,rising to the dynamic process of interaction between people and the environment,taking into account the impact of internal and external factors.The residents "behavior model" as an intermediary variable into the park environment to promote the healthy recovery of residents in the causal relationship,revealing the park park to restore the inherent principles of the environment.The research is mainly aimed at the following two aspects: First,the extraction and quantification of the characteristics of the restoration of the community park,and to reveal the restorative environment effect mechanism and effect path of community park;Second,to explore the community park strategies and modes of restorative environmental space optimization.In this paper,we use the method of induction and reasoning,qualitative and quantitative,theoretical and empirical,and take the main urban area of Chongqing as the case area,and carry out three aspects of empirical research: First,through the field of open survey and behavioral observation method to explore the community park environment residents behavior patterns;Secondly,through the combination of questionnaire and photo measurement method,scenic beauty estimation method and factor analysis method,the characteristic factors of the restoration environment of community park were extracted,and the characteristics of the restored physical environment of community park were quantitatively evaluated to determine the physical environment characteristic factor And the psychological environment characteristics of factors and the relationship between the recovery effect;Thirdly,through the analysis of the structural equation model and the mediating effect test,the key influencing factors and the effect of the restoration effect of the community park environment are analyzed,which constitute the explanatory framework of the restoration mechanism of the community park.The study yielded the following results: First,the restoration environment of the community park is mainly composed of naturalness factor,perceiving factor,resting factor and activity factor in four dimensions,and the naturalness factor played a main role to resilience effect of residents.Based on the quantitative evaluation of the restoration factors of the community park,the prediction model of the environmental restoration degree of the community park was established,and the physical environment was determined The relationship between the characteristic factor and the psychological environment characteristic factor and the restoring effect.It is concluded that the environmental characteristics satisfying the restorative needs are: natural characteristics,distance characteristics,charm characteristics and privacy characteristics.Secondly,it constructs the theoretical model of the causal relationship between the restorative environment of the community park and the residents' restoring effect,as well as the conceptual framework of the community park's restorative environmental effect mechanism.It is proved that residents 'behavior patterns plays a mediating effect in the restorative environmental effect mechanism of city parks,and the mediation effect of the static behavior pattern is greatest.Based on the effect mechanism,the key influencing factors and the main behavior patterns constitute the explanatory framework of the restoration effect of the community park,the path and effect of the four dimensions of the community park restoration environment are analyzed.Thirdly,the paper constructs the grid of " space design elements of community park restorative environment",and puts forward the thinking consciousness and principle of the optimization of the community environment in the restoration of the community park,and the spatial optimization strategy;the integration of the research results from the community park to restore the overall environment,Line system,constituent elements,behavior support four aspects of the development of 37 space optimization model.
