摘　　要：早期千村一面的乡村建设模式已经不能满足村民对于美好人居环境的需求。本文选择成都市生态环境保护与乡村振兴的重要据点——都江堰的平原乡村民安村为研究对象,通过现场实测和ENVI-met模拟相结合,评估民安村夏季微气候舒适度,并筛选出影响其舒适度的关键气候参数,调整村落布局及植物景观配置模式改善其夏季微气候舒适度。结果显示:民安村夏季闷热且整体风速较低,微气候舒适度较差,“很热”等级占比高达91.3%;太阳辐射是影响微气候舒适度的直接因子,空气湿度是间接因子。指出在新农村改造过程中应当通过一系列技术手段调整村落西侧及街巷空间南北向的遮阴面积,有效减少太阳辐射、提高相对湿度,改善其夏季微气候舒适度。The early“one pattern for one thousand villages”rural construction model can no longer meet the demand of villagers for a better living environment.This study selects Min’an Village,a key point for ecological environment protection and rural revitalization in Dujiangyan City,Chengdu City,as the research object.By combining on-site measurements with ENVI-met simulation,it evaluates the summer microclimate comfort in Min’an Village and selects key climatic parameters affecting its comfort.The study proposes adjusting the village layout and vegetation landscape configuration to improve its summer microclimate comfort.The results show that Min’an Village is hot and uncomfortable in summer,with a very high proportion(91.3%)of very hot conditions,and overall low wind speeds.Direct factors affecting comfort include solar radiation,while air humidity indirectly affects the Wet Bulb Globe Temperature(WBGT).During the process of rural revitalization,a series of technical methods should be used to increase shading,especially on the west side of the village and in street and lane spaces to the north and south.It can effectively reduce solar radiation and increase relative humidity to improve the comfort of its summer microclimate.
