摘　　要：在阴影区原理的基础上,根据《热环境根据WBGT指数对作业人员热负荷的评价》标准,课题组对海口骑楼街区内东西向的中山路和南北向的博爱北路进行了热环境参数测试.根据测试结果,划定了有效阴影区、无效阴影区、热调节有效阴影区出现的时段,并确定了热调节有效阴影区时段内日照区的最小范围.通过对日照区最小范围的绿化种植,可以较为有效的调节街道的热环境状况.最后,给出基于阴影区理论的生态步行街道的设计程序.Based on the shadow area theory and the standard of Hot environments-estimation of the heat stress on workingman based on the WBGT-index.The researchers carried out a test on thermal indexes at north-south Bo′ai North road and east-west Zhongshan Road in Qilou block of Haikou City.According to the test results,the time period of valid shadow area,invalid shadow area,thermal adjustment valid shadow area are delineated.The minimum range of the sunshine area in the thermal adjustment valid shadow area period is determined.Through the greening of the minimum range of sunshine area,the thermal environment of the street can be adjusted more effectively.Finally,the design procedure of ecological pedestrian street based on the theory of shadow area is given.

关 键 词：WBGT指数、有效阴影区、热调节有效阴影区
