4.Scientific discoveries

In recent years, the systematic and innovative research works were conducted on carbon and nitrogen turnover processes and greenhouse gas emission in wetland and agricultural ecosystem. Creative achievements on greenhouse gas emission from arable soil and wetland were accomplished. The conversion of rice fields into crab ponds in the Taihu Lake basin significantly increased the greenhouse gas emissions; we set up the emission factors of CH4 and N2O in different types of freshwater aquaculture systems, and estimated the global budget of greenhouse gas emissions in freshwater aquaculture systems at 6.04 TgCH4. The key factors affecting spatial variation patterns of CH4 emissions were identified in freshwater wetlands on the different scales such as different type of wetland, and inter-plants and intra-plant within the same wetland; preliminarily budget of the annual CH4 emissions in China's wetland was estimated at 7.6 TgCH4. The invasion of Spartina alterniflora significantly increased CH4 emission by shifting the methanogenic substrate from hydrogen plus carbon dioxide to trimethylamine and functional methanogenic arechaea from Methanococcales to Methanosarcinaceae; The invasion of Spartina alterniflora increased significantly the magnitude of soil organic carbon in the coastal wetland by 2.63-8.78 times, which was mainly accumulated in the soil macroaggregates. The organic carbon content in the silt and clay fractions regulated the formation of soil aggregates, and there was a linkage between aggregates and microbial communities. The black soil exhibited the function of nitrogen retention with the dissimilation reduction of nitrate to ammonium; the composition of different organic materials was regulated by lignin components.
