摘要:
生活型街道热环境研究对于生态宜居城市的建设具有重要意义。以徐州市典型生活型街道为例，利用正交试验和Envi-met模拟研究乔木绿化特征对街道峡谷空间的微气候及热舒适的影响规律。研究发现：(1）乔木叶面积指数（LAI）与街道风速、气温、太阳辐射温度和生理等效温度（PET）均呈负相关，与含湿量呈正相关；枝下高与风速呈正相关，与气温、太阳辐射温度和PET呈负相关；随着乔木冠幅的增大，街道风速、气温、辐射温度和PET都呈先降后升的趋势;乔木绿化覆盖率与街道风速、气温、太阳辐射温度和PET都呈负相关。(2）乔木冠幅和绿化覆盖率2要素对街道微气候和热舒适的影响最为显著；乔木绿化对南北向街道的影响更为显著。（3）对于该研究模型，乔木绿化特征的最优组合是LAI为4.8，枝下高为5 m，乔木冠幅为5 m，绿化覆盖率为60%。基于研究结论，提出典型生活型街道乔木绿化策略。
Abstract:
The research on the thermal environment of living-style street canyon space is of great significance for the construction of ecological and livable cities. This study takes a typical residential street in Xuzhou City as an example, and uses orthogonal experiments and Envi-met simulation to study the impact of tree greening characteristics on the microclimate and thermal comfort of street space. Results were found that: 1) Tree leaf area index (LAI) was negatively correlated with street wind speed, temperature, solar radiation, and PET, but positively correlated with air humidity; The height under branches was positively correlated with wind speed, but negatively correlated with temperature, solar radiation, and PET; As the canopy width of the trees increased, the street wind speed, temperature, radiation, and PET all showed a trend of first decreasing and then increasing; The coverage rate of tree greening was negatively correlated with street wind speed, temperature, solar radiation, and PET. 2) The two factors of tree crown width and green coverage had the most significant impact on the microclimate and thermal comfort of streets, with more significant impact of tree greening on north-south streets. 3) For this research model, the optimal combination of tree greening characteristics was LAI of 4.8, branch height of 5 m, tree crown width of 5 m, and green coverage rate of 60%. Based on the research findings, the greening strategies with trees for greening typical residential streets were proposed.
