| 摘 要： | 利用涡度相关观测技术研究了2010年10月至2011年9月浙江省临安市太湖源镇人工高效雷竹Phyllostachys violascens林生态系统的水汽通量变化特征，同时结合常规气象观测数据，分析了水汽通量对净辐射的响应。结果显示:雷竹林全年水汽通量基本为正值，夏季最高，春秋季变化特征相似，冬季最低 ，最高月份为7月，最低月份为1月。实验区全年降水量为1 201.72 mm，蒸散量为669.84 mm，蒸散量占全年降水量的55.74%，较人工针叶林，落叶松Larix gmelinii林，红松Pinus koraiensis林，柞树Xylosma racemosum林，杂木林，杉木Cunninghamia lanceolata林等，雷竹林蒸散量偏低。2月、10月和12月蒸散量略大于降水量，其余月份蒸散量均小于当月降水量，以6月份降水量与蒸散量差别最大。雷竹林水汽通量与当地净辐射有极显著的相关性，其相关系数为0.600～0.017。图4表1参13

| Abstract: | Using eddy covariance technology，water vapor flux variation in a high-efficiency managed Phyllostachys violascens （Lei bamboo） ecosystem in the Zhejiang Modern Demonstration Zone was observed from October 2010 to September 2011. The precipitation and net radiation responses to water vapor flux were studied using a correlation analysis. Results showed that the annual water vapor flux was positive. The maximum water vapor flux occurred in July and the minimum in January with similar variation in spring and autumn. Annual evapo-transpiration of the Lei bamboo stand was 669.84 mm，which was slightly lower than other types of woodlands. Annual precipitation was 1 201.72 mm，which was about 55.74% of the annual precipitation （669.84 mm）. Except in February，October，and December，evapo-transpiration was less than precipitation. The greatest difference between evapo-transpiration and precipitation appeared in June. There was also a high correlation （r = 0.600-0.017） between water vapor flux in a Lei bamboo stand and net radiation.［Ch，4 fig. 1 tab. 13 ref.］ |
