The purpose of the emergence of cities is to enable people to live a better life,but the development of cities does not promote the harmonious coexistence between "people" and "green".For a long time,cities fill people's expanding material needs by squeezing green space,making cities generally in a state of high density.With the continuous development of city park green space will be narrowed or even disappear gradually,people will find it hard to enjoy the fresh air,sunlight,and public recreational space,and these phenomena also presented the trend of widening,if not for effective prevention and control,to people's life and survival will soon produce serious threat.At present,some foreign scholars have conducted relevant studies on the relationship between urban natural environment and human physical health.From the research results,when citizens are in a crowded environment,they will have negative feelings and increase psychological pressure.When people are in an environment with insufficient privacy,it can increase people's psychological anxiety.At present,urban green park is an important place for people to release psychological pressure and relax.Under such a background,it can be seen that the park green space under the highdensity urban area occupies a very important position in the urban composition,and its special positioning determines that it needs to undertake complex functions such as improving the urban ecological environment,integrating various urban Spaces and relieving the physical and mental pressure of urban residents.Through active intervention of park green space on the health of people,it can provide people with a place to improve physical activity and promote healthy life of people,so that people's needs and social development can be met.Therefore,it is necessary to study the influence mechanism of park green space on human health in high-density urban areas to improve the public health problems caused by urban development.In this thesis,from the high density urban area of chengdu-select "public" and "service domain widely" representative around the park green space as the research sample,on the basis of predecessors' research results,by means of GIS technology,the analysis is suitable for high density urban park green space characteristic indexes,two-dimensional green quantity,accessibility,the degree of visibility,POI,abortion thermal indicators,has been clear about the four studies in their sample to park at the macro homogeneity and difference.Then,the mediating variables and regulating variables are introduced into the regression model of the impact of park green space on human physiology and psychology,and a more complete and in-depth research framework is proposed.The conclusion show that:(1)From a macro perspective,the park green space in high-density urban areas has certain homogeneity and difference,and they all have high two-dimensional green amount,good accessibility,poor visibility,POI degree and heat value of human flow with a general degree or above.Through further weight assignment,it is concluded that the characteristics of the four parks difference is: Wangjiang tower park > Huanhuxi park > People's park > Nanjiao park(wuhouci museum garden area).(2)under the condition of(1)the research sample,found under the micro level,in view of the high density urban park green space environment perception dimension mainly for "peace","space","rich" and "refuge","culture","outlook" and "social" seven dimensions,including "shelter","peace","social" and "space","rich" the five dimensions of physical and mental health has certain prediction effect.,mainly embodied in the "shelter","peace","social","space","rich" in addition,five dimensions,in the process of experimental analysis,perceptual dimensions and their index to predict regression significance(prediction)is greater than the ratio on physiological indexes of regression(prediction)prediction significance is bigger,because then emphatically in the further analysis for dimension of awareness and psychological rehabilitation of the effect between the inspection;(3)In the further test of mediating effects,three different behavior patterns are introduced as mediating variables,and it is found that "static behavior" is part of mediating effect between "quiet" dimension and human psychological recovery,while "dynamic behavior" and "passing behavior" have no mediating effect between each dimension and psychological recovery.(4)in further the regulating effect of inspection,the introduction of state level of empathy as a moderator variable,find the exception of the "rich" dimension between the other six dimensions and mental recovery adjust action,and through a simple slope analysis state of empathy in the "culture","outlook","social" and "space" and "peace" between dimensions and human physiological recovery enhanced regulation effect,the effect of the "social" dimension is stronger,but the overall is not obvious.In the end,through the study conclusion makes it a more comprehensive and accurate understanding of the park green space effects on human physiological and psychological mechanism and related theory,and from the perspective of macro and micro planning optimization design strategy,especially in the micro level,respectively,analyses the combination of single dimension and best dimension,promoted and architectural planning,landscape architecture discipline focus on material and elements established close ties,and sums up the high density city(area)the park green space landscape design with the optimization of ideas,to better serve humanity.
