Sources of Methane in China: A Program to Estimate the Emissions from Rice Paddies, Biogas Pits and Urban Areas: Annual Progress Report.

摘要

The main objectives of our program are (1) to determine the flux of methane from rice fields in China and estimate the global emissions of methane from rice fields, (2) to determine whether the estimated 7-10 million biogas generators in China are contributing to the global increase of methane, and (3) to conduct exploratory studies of emissions of other environmentally significant trace gases from rice fields and biogas generators. The last two objectives have been fulfilled. 3 refs.
