| Urban parks are one of the places with high frequency of daily activities of urban population,which can meet the needs of people to be close to nature and return to nature.The appropriate park microclimate environment is an important factor affecting the use of the public,it can effectively improve the use rate and provide comfortable rest places for the residents.The paper is from the perspective of adaptive microclimate design,taking White Pagoda Park in Hangzhou as the research object,describing and analyzing the change rule of the microclimate factors and comfort in three seasons of spring,summer and winter in the sample land through field survey,field measurement and other software such as Rayman1.2,SPSS23.0 and Excel2007.Besides,The effects of the spatial structure of the park on the microclimate and its comfort are discussed.On the basis of the measured data and analysis,the adaptive design strategy of the park microclimate is put forward,and the following conclusions are drawn:(1)The top cover,the facade enclosure and the bottom material are the main factors affecting the change of the outdoor microclimate elements,among which the top cover is the most significant;(2)The influence of different microclimate factors on their comfort is different.The correlation size is: solar radiation > air temperature > relative humidity > wind speed;(3)The comfort degree of the microclimate in the places with different spatial structure characteristics in summer(higher temperature)is: full shade with semi-open rigid paving msesuring point > full shade with closed lawn pavement msesuring point > part-time shade with semi open rigid paving msesuring point > no shade with semi-open rigid paving msesuring point > no shade with open lawn paving msesuring point.> no shade with open rigid paving msesuring point;the comfort degree of the microclimate in the places with different spatial structure characteristics in winter(lower temperature)is is: no shade with open rigid paving msesuring point > no shade with open lawn paving msesuring point > part-time shade with semi-open rigid paving msesuring point > no shade with semi-open rigid paving msesuring point > full shade with semi-open rigid paving msesuring point = full shade with closed lawn pavement msesuring point;(4)The landscape design can improve the local microclimate,but in the background of the climate,especially in the extreme weather conditions,it can not break away from the influence of the climate and form a qualitative change in the comfort degree.The greater significance of it is to provide a safe and healthy outdoor environment for the users. |
