西安市冬季海绵城市街谷与传统城市街谷微气候对比分析

Comparative Analysis of Microclimate Between Sponge City Street Valley and Traditional City Street Valley in Winter in Xi’an

为了了解新型海绵城市街谷对于冬季雨雪后的街谷内微气候调节能力与传统城市街谷的差异性,本文选取了西安市海绵城市试点区沣西新城内一处海绵城市街谷,并与之对应选取了一处传统城市街谷进行微气候数据测试与分析。通过测试分析发现:新型海绵城市街谷内冬季雨雪后的温度和湿度的自我调节能力远远高于传统城市街谷,但是对于风速和CO浓度的调节能力与传统街谷基本相同。

In order to understand the difference between the microclimate regulation ability of the new sponge city street valley and the traditional city street valley after winter rain and snow,this paper selects a sponge city street valley in Fengxi new city,Xi’an sponge city pilot area,and selects a traditional city street valley to test and analyze the microclimate data.Through the test and analysis,it is found that the self-regulation ability of temperature and humidity in the new sponge city street valley after winter rain and snow is much higher than that in the traditional city street valley,but the ability to adjust the wind speed and CO concentration is basically the same as that in the traditional street valley.
