【摘要】 城市规划气象环境多尺度数值模式系统为城市规划气象环境影响定量评估提供了有效的模式工具。本文利用该模式模拟了绿地布局为集中型和分散型、绿地面积百分比分别为8%、16%、32%、48%和60%条件下,城市大气温度、湿度、风速、城市大气扩散条件的变化,并以成都城市绿地规划为例,模拟分析了绿地规划前后城市气象环境的差异,揭示了城市绿地对气象环境影响的可能机制。更多还原

【Abstract】 The multi-scale numerical modeling system is an effective tool to evaluate the atmospheric physical environment amid urban planning quantitatively. With the adoption of the model, the variations of urban temperature, humidity, wind speed, atmospheric diffusion conditions, and their impact on urban atmospheric environment under the dispersed and converged green spaces with different proportion are simulated respectively. Taking green space planning of Chengdu as the example, the modeling is carried out to analyze the difference between the urban atmospheric environments in Chengdu before and after the planning.更多还原
