由于大氣中CO_2、CH_4和N_2O等溫室氣體濃度的增加,致使全球氣候系統(tǒng)正在發(fā)生著人類有史以來從未有過的急劇變化,主要表現(xiàn)在全球氣溫升高及由此導(dǎo)致的海平面上升,降水分布變異、沙漠化加劇、自然災(zāi)害發(fā)生頻繁等一系列嚴(yán)重的全球環(huán)境問題。全球氣候變化必將對陸地生態(tài)系統(tǒng)以及社會經(jīng)濟(jì)系統(tǒng)產(chǎn)生廣泛的影響。從20世紀(jì)70年代后期開始,全球變化研究受到科學(xué)界的普遍重視,而陸地生態(tài)系統(tǒng)碳氮循環(huán)是全球變化和全球碳氮循環(huán)的重要組成部分,是預(yù)測未來大氣CO_2、CH_4、N_2O和其它溫室氣體含量、認(rèn)識大氣圈與生物圈的相互作用等科學(xué)問題的關(guān)鍵。

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.
