| 摘 要： | 利用涡度相关系统,对我国西北旱区某葡萄园进行了一个生长季度的观测,得到了日尺度水碳通量耦合的初步关系,表明葡萄园水碳通量的变化白天存在较高的一致性,且二者均呈双峰型曲线;在一定时间范围内,二者存在较明显的比例关系,即葡萄园毎平方米毎秒固定1 mgCO2,同时会蒸腾2.2×10-9mm水汽。该研究为揭示葡萄园水碳耦合关系提供了一定的参考依据。

| Abstract: | In this study,eddy covariance system was used to measure the vineyard's water and CO2 flux in an arid area of northwester China.The results showed that there is a high consistency between variation of water and CO2 flux during the day time,it is means that each square meters of vineyard fixed 1mg CO2 one second,will also transpiration 2.2 × 10-9 mm moisture.This work can be a reference for the future study of water-carbon flux coupling in the vineyard. |
