模拟及分析街头绿地植物群落对夏季小气候影响

Simulation and analysis on the influence of street green space plant communities to summer microclimate

选取北京城市绿地中具有代表性的几处植物空间结构,利用仪器测量与ENVI-met软件,对植物空间结构温湿度在不同时间段的阶梯变化进行了实测与模拟,探索了乔草结构、裸露草地、灌草结构与乔灌草结构四种植物空间结构与空气温度、相对湿度等影响要素的关系,指出植物空间结构对缓解城市高温机制有着不同的效果。

This paper selected the representative of several plant space structure of urban green space in Beijing,using the instruments measurement and ENVI-met software,measured and simulated the step change of plant space structure temperature and humidity in different time,explored the relationship of joe grass structure,bare grassland,shrub and grass structure and shrubs and spatial structure mechanism four plant space structures and air temperature,relative humidity and other influence factors,pointed out that the plant space structure had different effect on relieving the city high temperature mechanism.
