Research On Activity Spatial Planning Strategy Of Mianyang Mountain Park Based On Microclimate Adaptation

People living in the city are eager to improve their quality of life on their own,so they work hard,and the pressure of life in the invisible is getting bigger and bigger.Unconsciously,they have sub-health symptoms.How much people are eager to go hiking without having to go hiking.If you don't have to travel,you can find a green and empty place to breathe in the fresh environment at home.Adults and children can move around in such a resting place,take a breath of air,put down pressure and restore health.Urban mountain parks are places where people can get close to nature and send mountains and rivers in the city.At present,when designing urban mountain parks,there are fewer concerns about the thermal environment of the activity space,which makes some space thermal environments poor,and the tourist stay time is short,which causes waste of space resources and greatly reduces the utilization efficiency of the park.Therefore,this paper takes Mianyang City Mountain Park as an example to study the outdoor thermal comfort problem in hot summer and cold winter regions.This paper aims to meet the outdoor thermal comfort of the tourists.Firstly,in the summer,autumn and winter seasons,on-site measurement and thermal comfort questionnaire survey were conducted on 11 activity spaces of the selected Mianyang City Mountain Park.And quantitative and qualitative analysis of the measured data,summarizing the basic characteristics and laws of the thermal environment of summer,autumn and winter in the outdoor activity space of urban mountain parks in Mianyang area.At the same time,the thermal comfort of each measuring point in summer,autumn and winter is analyzed.The physiological equivalent temperature(PET)corresponding to each questionnaire was calculated by Ray Man software,and derive the thermal comfort threshold range for the outdoor environment in summer,autumn and winter.Then using ENVI-met software to simulate and analyze the sensitivity of planning and design elements to the thermal environment of the active space,it is found that the formation of outdoor thermal environment is affected by many factors,indicating that the application of climate adaptive design requires a composite strategy.The thermal environment of the activity space may be thermally comfortable.Finally,from the site selection,plane shape,scale size,layout,interface design,greening and water body,the activity planning strategy of Mianyang Mountain Park based on microclimate adaptation is proposed to improve the utilization rate of park activity space and promote mountain parks.Good service to the public,to lay the data foundation for the future planning and design of urban mountain parks in Mianyang based on microclimate adaptation.The research results in this paper are an important supplement to the outdoor thermal comfort research in the hot summer and cold winter regions and Mianyang region.They are also an important supplement to the spatial adaptation design theory of outdoor activities in Mianyang,and are complementary to the application research of ENVI-met simulation software.The data analyzed by the above surveys can be used in many future work.
