A Research On Landscape Design Of Urban Park For Elderly In Kunming City Based On The Design Mechanism Of Microclimate Adaptation

Under the trend of aging in China,the elderly have become the main users of urban park,and urban parks play an important role in enriching the daily life of the elderly.Taking the high activity frequency space of the elderly in Kunming City Park as the research object,this thesis attempts to summarize the optimization strategy of landscape design of urban park for the elderly based on the microclimate adaptive design mechanism.Through the field research on the activity rules of the elderly,the activity preferences and rules of the elderly were obtained,and the landscape factors related to summarize the activity behaviors of the elderly.Summarize the selected activity space in park climate test results,obtain the main microclimate characteristics of summer and winter festival of activity space in parks of Kunming,based on the activity regularity of the elderly,the design mechanism of microclimate adaptability for the parks of the elderly in Kunming City was summarized.The ideal model of activity space for the elderly in park is established,and the influence of different landscape factor combinations on microclimate in the ideal model is simulated.The UTCI values of each observation point in the ideal model are calculated,and the key landscape factor control indexes of parks for elderly microclimate construction are summarized.Propose optimization strategies for landscape design of urban parks for elderly based on microclimate adaptability.It includes the following four aspects: first of all,the use of "blue and green infrastructure".Set landscape elements in the site to adjust the microclimate environment.Secondly,Using shading facilities.Using the combination of natural and artificial shading measures.Thirdly,site wind environment construction.Make use of the dominant wind in summer,create the wind environment inside the site,and prevent the cold wind in winter.Lastly,Site activity space design strategy.According to the activity rules of the elderly and the site microclimate conditions,the specific design of different activity spaces.
