Study on the Effects of Human Activities on Climate Change Ⅰ. Green House Gases and Aerosols
人类活动对气候影响的研究Ⅰ.温室气体和气溶胶

Extensive researches on the sources and sinks of greenhouse gases, carbon cycle modeling, and the characterization of atmospheric aerosols have been carried out in China during the last 5 years or so. This paper will present the major achievements in the fields of emissions of greenhouse gases from agricultural lands, carbon cycle modeling, the characterization of the mineral dust of Asia, source iden tification of the precursors of the tropospheric ozone, and the observations of the concentrations of at mospheric organic compounds. Special more detailed information on the emissions of methane from rice fields and the physical and chemical characteristics of the mineral aerosols are presented.
