Study On The Influence Of Waterscape Design On Microclimate In Five Minute Living Area Of Harbin

Under the background of the gradual deterioration of climate,microclimate determines the quality of people's production,life and health to a large extent.Microclimate research is widely used in various space fields,in which public space in residential areas is an important space field in which people are closely contacted with the environment,and its microclimate will have an important impact on people's daily life,therefore,the study of microclimate in residential areas is one of the focuses in the field of microclimate research.The landscape can improve the microclimate to a certain extent.As an important landscape element in the residential area,waterscape is one of the important factors affecting the microclimate.Reasonable design of waterscape can effectively promote its microclimate regulation benefits.The idea of microclimate suitability runs through the design of waterscape in the residential area,which plays an important role in improving the microclimate in the residential area.This paper takes the waterscape of the five minute living area in Harbin as the research object.Firstly,through the literature research method,this paper combs the existing achievements and methods of the research on the influence of waterscape on microclimate,and combs the related concepts and basic theories.Secondly,on the basis of literature research and basic concept theory research,the current situation of waterscape in Harbin residential area is investigated,and the research category is determined as five minute residential area,and the data collection of air temperature,relative humidity and wind speed in microclimate factors is carried out with the method of field measurement.By analyzing the current situation of the investigation,the different forms of waterscape in Harbin are summarized into four aspects:orientation,layout,area and type,and these four aspects are regarded as the factors that affect the microclimate.At the same time,the building itself has become an important factor that can not be ignored.Therefore,the building orientation is classified as the influencing factor.According to the different forms of waterscape,the waterscape of 9 five minute residential areas with typical forms of waterscape is selected as the research object,and observation points and control points are set up to measure the microclimate factors of each measurement point.Thirdly,regression analysis method,control variable comparison method and human settlements climate comfort evaluation method are used to process and analyze the measured data.Through the linear regression analysis of air temperature,relative humidity and wind speed,it is concluded that the influence weight of waterscape on relative humidity and wind speed is small and not considered.The influence of waterscape on air temperature is very important.The influence degree of different forms is from large to small:area,building orientation,orientation,type and layout.According to the calculation results of three methods:(1)Increasing area is the primary factor to improve microclimate.(2)The microclimate can be effectively improved by arranging Waterscape in the public space with the dominant wind direction and the surrounding buildings in the north-south direction.(3)Natural revetment can improve microclimate better.(4)The microclimate can be improved better by decentralized layout than by centralized layout.(5)Emergent plants and fountain landscape can adjust microclimate to a certain extent.Finally,based on the analysis of the results,the design principles and strategies are summarized,and two water features design principles based on microclimate regulation are put forward,which are weight principle and comprehensive principle.Based on the design of microclimate suitability and the view of residential landscape,this paper explores the specific design strategies of location,layout,area and type of waterscape.This study has practical significance for improving microclimate environment of residential areas,promoting urban microclimate governance and healthy development of urban residents.It provides a theoretical basis for the water feature design of the five minute living area in Harbin Based on the microclimate regulation,and provides a reference for the study of the influence of the water feature design of the residential area in other regions on the microclimate.
