冠层CO2浓度变化是反映森林生态系统与大气能量交换的重要指标。以2010-2011年间对泰山区域森林冠层进行连续观测得到的CO2浓度数据为数据源,给出观测数据的处理方法,按日、月、季节尺度3种不同的时间尺度对该地区冠层CO2浓度的变化进行分析,获取不同时间尺度上的变化特征,所得到的成果为进一步研究冠层CO2的空间分布格局的提供基础资料。
Changes in canopy CO2 concentration is an important indicator of energy exchange between forest ecosystems and the atmosphere. The data of CO2 concentration obtained from continuous observation of forest canopy in Taishan region from 2010 to 2011 were used as data source. The treatment methods of observation data were given. The canopy CO2 in the canopy at the three different time scales of day, month and seasonal scale The changes of the concentration of CO2 in the canopy were analyzed to obtain the variation characteristics at different time scales. The obtained results provide the basic data for further studying the spatial distribution pattern of canopy CO2.
