[Gas exchange measurement system based on chamber method and its applications in gas exchange research of plant ecosystems].
Gas exchange measurement system based on chamber method is commonly used for the researches of carbon and water cycles in plant ecosystems, especially for the researches in soil and plant organizational scales. According to the gas path frames of the measurement system, this paper summarized in detail the principles and computing methods of closed, semi-closed, open, and semi-open path gas exchange measurement chamber systems. The commercial gas exchange measurement chamber systems commonly in use were enumerated, and the development and applications of some handcrafted systems were also reviewed. Finally, some disadvantages of gas exchange measurement chamber systems were indicated, and their improvement measures were suggested.
