Distribution of Organic Carbon in the Sediments of Xinxue River and the Xinxue River Constructed Wetland, China
Fig 2
The spatial distribution of light fraction organic carbon (LFOC).
Bar plots showing the spatial distribution of light fraction organic carbon (LFOC) in the Xinxue River (XR) and Xinxue River Constructed Wetland (XRCW). A = upstream location of XRCW; B = downstream location of XRCW; C = upstream location of XR; D = downstream location of XR. Bars sharing the same lowercase letter (a or b) are not significant at α = 0.05 (Duncan test).
