摘要/Abstract

摘要：

植物群落蒸散量和CO₂交换量的测定方法多种多样。该文以水分、CO₂动态的区域性整合为目标,开创了一种新的、同时测定群落蒸散量和CO₂交换量的方法——LI-6262 CO₂/H₂O分析仪接气室法。借助这种方法测定了内蒙古锡林河流域典型草原区群落蒸散量和CO₂交换量,取得了较好的结果。该方法将群落的重要生态过程:蒸散与光合、呼吸作用的测定联系起来,也因此得到一系列表征群落特性的有用指标;同时该方法具有精度高、简便易携带、适于野外操作等特点,经进一步改进后可广泛用于草原、沙地及湿地植物群落的气体通量测定。对于精确研究草原区各种植物群落类型的水分利用、光合和呼吸特性及草原区植被在全球气候变化中的地位和作用等有重要的实用价值。

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
