Microclimate Study On The Water Adaptability Space Of Pond Settlement In Southern Henan Province

The 20 th National Congress of the Communist Party of China proposed to strengthen the construction of rural spiritual civilization.Currently,China has taken multiple measures to protect village culture.However,with the development of urbanization,many ponds and water landscapes are facing disappearance.Therefore,it is necessary to seek harmonious development between people and the environment and create a harmonious relationship between people and water environment.This study takes the pit and pond settlements in southern Henan as the research object.First,collect and sort out related literature at home and abroad,and sort out related concepts.Second,on the basis of document collation and field research,three representative pit and pond settlements of different forms were selected.Third,through field research and questionnaire survey,collect residents’ subjective evaluation of the comfort of different village spaces.Fourth,in order to objectively evaluate microclimate comfort,the element indexes and climate indexes of water adaptability space are selected as independent variables and dependent variables.Fifth,analyze the correlation between the village morphological element data and the cooling value.Through the regression equation,a concise model including indicators of different factors is established.Based on the above research process,the following conclusions are drawn:(1)According to the statistical results of the questionnaire survey,the microclimate satisfaction of Xufan Village and Guanweizi Village in different spaces in summer is in the order of waterfront>road>street and alley in order from good to worse in winter.Roads > streets and alleys > Linshui;Dingliwan Village’s outdoor microclimate satisfaction in summer is Linshui > streets and alleys > roads > square in order from good to poor.In winter,roads>streets>near water>squares;(2)The range and intensity of water cooling during the day is better than that at night,and summer is better than winter;(3)The strength of water cooling is different in different village forms.Among them,Guanweizi Village(village completely surrounded by water body)> Xufan(village semi-surrounded by water body)> Dingliwan Village(water body on one side of the village);(4)Through the regression model,it is found that the water space of different villages is the best The strength of the element ratio and the cooling value of water bodies in different village forms.Among them,the influence of village morphological elements in Guanweizi Village and Xufan on the cold value of water body is in the order of water body ratio > average building height > greening rate > building density.The influence of village form elements in Dingliwan Village on the cooling value of water body is in the order of average building height>greening rate>water body rate>artificial underlying surface;(5)The wind environment also has an important impact on the cooling value of water body.The dominant wind direction and the water body work together to form ventilation corridors to enhance the cooling effect of the water body.Therefore,arranging water bodies in the upper wind direction of the dominant wind can maximize the cooling effect of water bodies;(6)Villages with low building density are conducive to the passage of wind,and villages with moderate building heights are conducive to air cooling in the shaded areas of buildings,thereby enhancing water body cooling.The scope of influence of cooling effect;(7)The blue-green space synergy effect formed by greening and water body is better than the cooling effect of a single factor.Therefore,the green area around the water body can be expanded appropriately to obtain a better cooling effect.Finally,based on the conclusions of subjective questionnaire survey and objective data research,the water-adaptive space design principles and strategies of pit and pond settlements based on microclimate adjustment are proposed:(1)Design principles of resilience,efficiency,comfort and rationality are proposed.Give full play to cultural advantages,optimize the comfort of outdoor microclimate,and create a village that is safe,harmonious and adaptable to environmental changes.(2)Propose a design strategy based on water body shape,green water body,and architectural shape layout to achieve the goal of optimizing the water adaptability space of the village.This study intends to propose a water-adaptive spatial form design strategy in the early stage of the planning,design and reconstruction of pit and pond settlements.Through the regression model of villages with different forms,builders can reasonably arrange the elements of village space to achieve the best outdoor microclimate state in harmony with the environment.
