System of Measuring Soil Carbon Flux Based on Wireless Sensor Network

CO2作为一种最重要的温室气体,其源、汇及通量的精确测量备受关注。土壤呼吸是影响大气CO2浓度变化的一个重要因素,通过土壤呼吸排放到大气中的CO2大约为68PgC・a-1,约占大气CO2总量的10%（Raichetal.,1992;刘绍辉等,1997;高会议等,2009）。但是,目前大范围准确地监测土壤CO2通量仍然面临巨大挑战。 With GreenOrbs deployed in the forest based on the Wireless Sensor Network （WSN）, a new device （Lr100GE-6400） was developed in this s...

Zusammenfassung:	CO2作为一种最重要的温室气体,其源、汇及通量的精确测量备受关注。土壤呼吸是影响大气CO2浓度变化的一个重要因素,通过土壤呼吸排放到大气中的CO2大约为68PgC・a-1,约占大气CO2总量的10%（Raichetal.,1992;刘绍辉等,1997;高会议等,2009）。但是,目前大范围准确地监测土壤CO2通量仍然面临巨大挑战。 With GreenOrbs deployed in the forest based on the Wireless Sensor Network （WSN）, a new device （Lr100GE-6400） was developed in this study. Five sample points with remarkable different soil surface structure characteristics in the forest were chosen for comparing the results measured with the Lr100GE-6400 and with Li-8100. Research results showed that the relative error of the Lr100GE-6400 is less than 7%.
