鄱阳湖秋季水-气界面CH4排放通量的区域差异及影响因素OA北大核心CSCDCSTPCD
Spatial heterogeneity and controlling factors of autumn CH4 flux at water-air interface in Poyang Lake of Jiangxi Province, China
有限的观测点以及空间的异质性已经成为准确估算湖泊水-气界面CH4通量的挑战.鄱阳湖是我国最大的淡水湖,为了解秋季湖区水-气界面的CH4排放通量,2010年10月利用密闭静态箱-气象色谱法对星子、都昌、南矶山和吴城4个湖区水-气界面CH4排放通量及气象、底泥、水体等因素进行了测定.研究表明,都昌湖区CH4排放通量平均值为0.26mg·m-2·h-1,显著高于星子(0.15 mg·m-2·h-1)、吴城(0.13 mg·m-2·h-1)和南矶山(0.…查看全部>>
Limited observation stations and high spatial heterogeneity of CH4 flux are the challenges for the accurate estimation of CH4 flux at water-air interface. Poyang Lake is the largest freshwater lake in China. In order to understand the autumn CH4 flux at the water-air interface in the Lake, closed static chambers and gas chromatography were adopted to measure the CH4 fluxes at the water-air interfaces in 4 inner lakes of the Lake in October 2010. The environm…查看全部>>
