doi:10.17521/cjpe.2007.0112

Abstract

Abstract:

Aims Our objective was to develop a new method for simultaneously measuring evapotranspiration and CO₂ absorption in plant communities using the LI-6262 CO₂/H₂O analyzer for regional integration of water and CO₂ dynamics.

Methods We measured evapotranspiration and CO₂ absorption of some plant communities in the typical steppe of the Xilin River Basin, China.

Important findings Our method enabled us to concurrently measure evapotranspiration, photosynthesis and respiration, the important ecological processes of communities and therefore obtain a series of valuable measurements of community characteristics. Our method is precise, the instruments are easily portable, and the method is adaptable for plant communities of steppe, sand lands and wetlands. The method has important practical value for study of the impacts of global change on ecological functions of steppe.

Key words: evapotranspiration, CO₂ absorption, LI-6262 CO₂/H₂O analyzer, typical steppe
