摘　　要：通过对春夏秋三季城市公园绿地不同下垫面内温湿特征的实地观测,研究不同季节各下垫面内的温湿效应变化特征及人体舒适度改善效应差异,结果表明,下垫面类型对其温湿特征和人体舒适度有显著影响,不同下垫面类型间温湿效应及人体舒适度水平有显著差异:下垫面类型在春季对其降温增湿强度有极显著影响,在夏季对降温强度有极显著影响,在秋季对降温强度有显著影响,各下垫面三季降温强度由高至低的排序是:林地>水体>硬质铺装>草坪>建筑,增湿强度由高至低排序为:林地>草坪>水体>铺装>建筑.下垫面类型在春、夏两季对其人体舒适度有极显著影响,秋季存在显著影响,三季均为林地的舒适度情况最好,建筑最差,人体舒适度改善效应由强至弱的排序为林地>水体>草坪>铺装>建筑.Based on field monitoring of microclimatic factors under different land cover types of urban park green space in spring,summer and autumn,the microclimate characteristics of different land cover types and their differential effects on improving human comfort were investigated.The results showed that land cover types exerted significant impacts upon human comfort level at various degrees in different seasons.Land cover types demonstrated significant cooling and humidifying effects in spring(P<0.01)while they only showed remarkably cooling effect in the summer time(P<0.01).When it comes to autumn,the cooling effect was statistically significant(P<0.05),but the efficacy was less compared with the other 2 seasons.The order of the cooling efficacy of land cover types was followed by woodland>water body>paving>lawn>building,and the order of humidifying efficacy was followed by wooland>lawn>water body>paving>building.Land cover types significantly influenced human comfort level in spring and summer(P<0.01),and showed some impacts in autumn(P<0.05).The comfort level of woodland was the highest among 3 seasons,while that of building was the lowest.The order of the improvement on human comfort level from various land cover types was followed by woodland>water body>lawn>paving>building.
