摘要/Abstract

摘要：

含碳温室气体浓度增加而加剧的温室效应是气候变化的主要原因。在线监测陆地生态系统中的CO2气体浓度并分析CO2通量，对了解局地气候及改善环境意义重大。设计了基于可调谐半导体激光吸收光谱技术的开放式CO2气体监测系统，于2010年4月份在中国科学院封丘农业生态实验站进行了小麦田间CO2浓度的实时在线监测。连续监测结果表明：主要受植被光合作用的影响，田间CO2浓度具有明显的日变化规律，基本特点是白天浓度降低，夜间浓度升高。本系统不需要气体采样、监测范围广、灵敏度高、响应时间快、调校简单，为农田环境的CO2浓度连续监测提供了有效的光学遥测方法。

Abstract:

The greenhouse effect exacerbated by the increase of carbon-containing gases is the important cause of the climate change. On-line CO2 concentration monitoring of terrestrial ecosystem and CO2 flux analyzing are crucial for knowing regional climate and improving environment. The open-path CO2 monitoring system based on tunable diode laser absorption spectroscopy technology was designed and used for CO2 concentration in-situ detection in wheat field at State Experimental Station of Agro-Ecosystem in Fengqiu, Chinese Academy of Sciences in April, 2010. The continuing monitoring results show that the variation of CO2 concentration has an obvious diurnal periodicity in cropland mainly influenced by vegetation photosynthesis, and the general characteristic of diurnal variation is that the concentration decreased in the daytime and increased at night. This system detected gas concentration with large range, high sensitivity, short response time, easy calibration without gas sampling. Thus, it’s an effective optical remote-sensing method for CO2 concentration continuing monitoring in cropland.

Key words: laser absorption spectroscopy, cropland, CO2 concentration
