在2012年中游航空遥感试验开展期间，在EC矩阵核心观测区开展移动式土壤呼吸5天1次的连续观测。\n
\n观测仪器：\n
\n中科院地球环境所LI8100移动式土壤呼吸测定仪。\n
\n测量方式：\n
\n使用已购置好的PVC管制作成土壤呼吸环，所制作土壤呼吸环总长10cm，于正式测定前嵌插入土壤，之后至少静置24小时；嵌入土壤4cm，地面保留高度6cm。基准面样点测定时间集中在上午9-12点，每样地设置三个重复样，根据涡动编号进行标记。\n
\n数据内容：\n
\n数据内容包含头文件信息和每5天1次的3次重复观测结果及平均数。\n
\n观测地点：\n
\nEC矩阵核心试验区内EC01-EC17号站点地块内，每样地设置3个重复样，其中EC15大满超级站在3个重复基础上加密了9个重复样。\n
\n观测时间：\n
\nEC01、EC03、EC05、EC10、EC11、EC12、EC13、EC14、EC17观测时间为2012年6月6日至8月20日每5天1次。\n
\nEC02、EC04、EC06、EC07、EC08、EC09、EC16为2012年7月1日至8月20日每5天1次。\n
\n观测期间部分观测点刚好灌水，该点当次则不观测。
