| 摘 要： | 基于马尼拉草坪的净辐射、气温、空气相对湿度、风速和土壤含水量等环境因子的实时观测,测算草坪环境连续时段的冠气温差,研究了不同天气条件下草坪冠气温差的日变化规律及其环境影响特征。结果表明晴天日出现规律性的日变化过程,阴天日与晴天日相似,雨天日变化幅度不明显;晴天日冠气温差与环境因子和土壤水分有较好的复相关关系,其中冠气温差与RH和VPD的相关性极显著。 |

| Abstract: | Based on real-time observation of net radiation,air temperature,air relative humidity,wind speed,soil water content in Manila lawn,the canopy-air temperature difference in continuous time was measured.The diurnal variation law of canopy-air temperature difference in different weather conditions and their characteristics of environmental impact were studied.The results showed that regularity diurnal variation process appears in sunny days,the situation in cloudy days is similar with that in sunny days,while in rainy days,the diurnal variation isn’t obvious.In sunny days,the canopy-air temperature difference has good multi-correlation with environmental factors and soil water content,among which,the canopy-air temperature has extremely significant correlation with RH and VPD. |
| Keywords: | Lawn Canopy-air temperature difference Environmental factors Soil water content |
