【摘要】：基于三維微氣候模擬軟件ENVI-met,以北京典型住宅區(qū)為研究對象,建立實況及設(shè)有屋頂綠化兩種場景下的三維數(shù)值模擬模型,對研究區(qū)的微氣候特征進(jìn)行模擬分析。結(jié)果表明:微氣候ENVI-met模型經(jīng)過多次參數(shù)校正后,模型模擬結(jié)果與實測結(jié)果較接近,能較好反應(yīng)微尺度氣候的分布特征;屋頂經(jīng)過簡單的綠化后具有較好的降溫增濕效果,使研究區(qū)平均溫度降低了2—3℃,相對濕度增加了2.7%,風(fēng)速由0.32—2.70 m·s-1降低至0.40—1.11 m·s-1,整體下降了0.34 m·s-1。ENVI-met通過三維模型可有效地應(yīng)用于微氣候模擬評價中,對評估當(dāng)?shù)匚夂蛟O(shè)計和城市規(guī)劃具有一定的應(yīng)用性。
[Abstract]:Based on the 3D microclimate simulation software ENVI-metand taking typical residential area in Beijing as the research object, a three-dimensional numerical simulation model was established under the two scenarios of real situation and roof greening, and the characteristics of microclimate in the study area were simulated and analyzed. The results show that the simulation results of the microclimate ENVI-met model are close to the measured results and can reflect the distribution characteristics of microclimate, and the roof has a better effect of cooling and humidifying after simple greening. The average temperature of the study area is reduced by 2-3 鈩，
