Efficient method was also taken up with for controlling and mitigating methane emissions from paddy fields.In summary, this study showed the feasibility of using new multi-temporal microwaveRadar ALOS data acquired in key dates during rice growing season to extract paddy ricegrowing area was tested. A modified rice backscatter model was developed on the basis oforiginal radiation transfer model for simulating paddy rice backscattering characeteristics. Themodified model and Genetic Algorithm Optimization Tool were synergized to reversephysical parameters and map rice biomass at spatial scale in the study area. At last, on thebasis of paddy rice planting area and farming practice data, biogeochemical DNDC modelwas utilized to simulate quantitatively estimating methane (CH_4) emission from paddy fieldsand represented some specific mitigation scheme.
