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.

Furthermore, transfer coefficient between total content and variable speciation including acid-soluble/exchangeable, reducible, oxidisable fraction of heavy metals are different. Transfer coefficient of total Cr is 0.65 in tailings area, but that of variable speciation is 0.26. In contrast with Cr,transfer coefficient of total Ni is 0.26, but that of variable speciation is 0.67. The similar characteristics on Pb and Zn in cultivated soil, namely, transfer coefficient of total Zn is high, but low for variable speciation, which is reversed for Pb. Transfer coefficient of total content and variable speciation in abandoned soil are low compared with above two fields soil, especially, variable speciation of Cu and Ni are not transported almost down soil profile.
重金属总量和活性态(包括弱酸提取态、可还原态、可氧化态)迁移率也表现出很大差异,尾矿区土壤Cr总量迁移率较高为0.65,而其活性态迁移率较低为0.26,Ni与Cr迁移特征完全相反,总量迁移率为0.26,而活性态迁移率为0.67;农田土壤中Pb总量迁移率低而活性态迁移率高,Ni与Zn特征相似,总量迁移率高而活性态迁移率相对较低;大棚地土壤中重金属迁移率均较低,Cu和Ni活性态几乎未发生向下迁移。
