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.]
