The Guizhou Plateau in SW China is dominated by carbonate rocks and karst landforms. Erosion rates are low, but soils are thin and soil erosion remains a serious problem. Hongfeng Lake is the largest reservoir on the Guizhou Plateau. A 35-cm-long sediment core was retrieved from the reservoir and six soil profiles were sampled in the catchment. 137Cs activity was measured in the core to establish...
Shibanqiao Reservoir (0.24km 2 ) and Xiaohe Reservoir (0.28km 2 ) have catchments of 6.00km 2 and 22.69km 2 , respectively. They essentially represent “strongly eroded” (Shibanqiao) and “mildly eroded” (Xiaohe) regions in Guizhou Plateau, southwestern China. Sediment cores were retrieved from the two reservoirs and soils were also sampled from their catchments. Mineral...
