Due to CO in the atmosphere_ 2、CH_ 4 and N_ The increase in the concentration of greenhouse gases such as 2O has led to a dramatic change in the global climate system that has never been seen in human history, which is mainly manifested in a series of serious global environmental problems, such as the rise in global temperature and the resulting sea level, the variation in precipitation distribution, the intensification of desertification, and the frequent occurrence of natural disasters. Global climate change is bound to have a broad impact on terrestrial ecosystems and socio-economic systems. Since the late 1970s, the research on global change has received widespread attention from the scientific community. The terrestrial ecosystem carbon and nitrogen cycle is an important part of global change and the global carbon and nitrogen cycle, and is used to predict the future atmospheric CO_ 2、CH_ 4、N_ The content of 2O and other greenhouse gases, and the understanding of the interaction between the atmosphere and the biosphere are the key scientific issues.



Haohan Chromatographic (Shandong) Application Technology Development Co., Ltd. has studied the use of static chamber/gas chromatography to conduct annual CO on grassland, clover and ryegrass in hilly areas of central Sichuan through field observation and indoor analysis_ 2、CH_ 4 and N_ based on the observation of CO flux, CO_ 2、CH_ 4 and N_ The diurnal and seasonal variation characteristics of 2O flux and the effects of environmental factors and plant growth on it.
