郑州浅山区村落街巷微气候影响机制分析
Analysis on the microclimate impact mechanism of village streets in the low mountain areas of Zhengzhou
摘要
Abstract
[Objective]This study aims to explore the influencing factors and regulatory mechanisms of micro-climate in village streets,create a more comfortable summer microclimate enviorment,reduce energy consumption and improve the quality of life of villagers.[Method]The street sample plots of 90 typical villages in the shallow mountainous areas of Zhengzhou City were taken as the research objects,and the data were collected through field research and drone mapping,etc.The real-time model of the sample plot was established by ENVI-met software,and microclimate parameters were simulated.Using statistical analysis methods,the impact mechanism of the three influencing factors of street aspect ratio,direction,and vegetation coverage in streets and alleys was explored.[Result]1)The research results of influencing factors indicate that the aspect ratio mainly regulates the microclimate of summer street space by reducing MRT;The vegetation coverage mainly regulates the microclimate of summer street and alley spaces by increasing RH;TA,RH,and MRT are all affected by the direction of the streets and alleys;2)Through range analysis it can be concluded that when H/W reaches 1.1,it can effectively shorten the time when streets and alleys are under extreme heat stress levels;3)When the vegetation coverage in the village is≥10%,the maximum effect of vegetation humidification and cooling can be achieved;4)The summer TA,RH,MRT,in North-South streets and alleys are better than those in East-West directions.[Conclusion]The influence mechanisms of H/W,FAC and direction on street microclimate in shallow mountain villages in Zhengzhou are different,and there is a certain correlation and optimal value among them.From the perspective of microclimate,the village street space can be transformed and designed,and the planning and design strategies can be improved to enbance the quality of rural human settlements.This study can provide reference for village renova-tion in similar geographical environments.关键词
