| 摘要:试验样地包括杨树片林、禾本科草坪和以丁香为主的灌木林。利用温湿度自动记录仪对3个样地周边的湿度在空间和时间上的梯度变化进行观测。每天测3个时段，每个时段持续90min，一周内选择气候相同或相近的天气重复做3次。实验结果描述了3个样地的湿度效应在时空上的变化特征及其相互之间的差异。该研究对探索绿地和非绿地之间的物质交换特点与规律，揭示和描述不同植物群落的湿度效应时空格局，对于北部地区城市园林绿地建设具有一定的理论意义和指导作用。 |
Abstract:The experimental places included the poplar woods, the lawn, and the clove shrub. The hygrothermograph were used to observe the spatial and temporal changes of humidity. The observations were conducted in three periods every day, each period for 90 minutes, and repeated for one week. The experiment results described clearly the characteristics of 3 kinds of sample and discrepancy each other. The result is important to probe the characteristic and law of material migration between urban greenbelt and bare land, and to depict increasing-effects spatiotemporal pattern of different plant communities and urban landscape planning |
