基于人体舒适度的植物群落空间微气候实测与模拟研究——以奥林匹克森林公园为例

Spatial Microclimate Simulation of Plant Community Based on Human Comfort--Taking Olympic Forest Park as an Example

选取北京奥林匹克森林公园为例,选择其中具有代表性的5种植物空间:乔草群落、裸露草地、灌草群落、乔灌群落与乔灌草群落,结合仪器测量与城市微气候模拟软件ENVI-met模拟,对这5种植物群落空间在不同时间段的温度、相对湿度以及风速等微气候因子的变化进行实测与模拟,分析其对于空气温度、相对湿度以及风速的影响关系,进而探究不同植物群落对人体舒适度的影响,最后提出群落结构优化建议,为绿地植物群落的合理构建提供参考.

Taking the Beijing Olympic Forest Park as an example and selecting five representative plant spaces,combined with instrument measurement and ENVI-met simulation,the step changes of the temperature and humidity of the plant space structure at different time periods are measured and simulated,and the influence of air temperature,relative humidity and wind speed of five plant species in grassland is analysed,and the impact on different plant communities on human comfort is explored.The strategy of community structure optimization and adjustment is put forward in order to rationally construct the plant community in green space.
