摘　　要：研究绿地结构对城市绿地系统改善城市环境和小气候的影响,对城市绿地的规划设计具有重要的理论和应用价值。2004年7月在太原市区选择3类9块绿地样地,利用HOBO Pro温、湿度数据采集器测定绿地边沿距地面高1．5m处的温度和湿度并以周围空旷地的温、湿度作对照,将二者的差值定义为绿地边界温湿度效应值。测试时间选择在一天中的8∶00、12∶00和18∶00 3个时段,测定1周。结果表明,绿地垂直结构和绿地面积等因子对绿地边界温湿度效应都不同程度地产生影响。绿地面积大小与绿地降温增湿效应成正相关,即绿地的降温增湿效应随着绿地面积的增加而增加。但是,随着面积的逐步增加,绿地的边界生态效应增加的幅度在减小。与绿地面积相比较,绿地垂直结构对绿地边界温湿度效应的影响更为显著。Studying the effect of green structure, area etc. on improving urban environment and microclimate is important to the planning and layout of urban green space. Three kinds of green space were selected in Taiyuan city proper, July 2004. The temperature and relative humidity at the edge of plots were measured by HOBO Pro hygrothermograph. The difference of the two temperatures or humidity was defined as the value of boundary effect. The results show that the relationship between green structure and area with boundary effects is positive correlative. At the same time, the increase rates of boundary effect tend to decrease along with the augment of area. Compared with the influence of area on boundary effect, the effect of green structure is more remarkable.
