grouped into stable streams, incised streams, aggrading streams, and streams with intensive bed load
motion. The stable streams are the rivers with a stable channel bed with little bed load motion, examples
are the Jiuzhai and Shengou creeks, and the Jialing and Ake rivers in the upper Yangtze River basin, the
Chexi and Shennong creeks in the Three Gorges reach of the Yangtze River, the Balan and Songhua
rivers in the northeastern China, Shangping Creek and the East River in the Pearl River basin, the Qingjiang
River in the upper Weihe River basin, and the Juma River in the suburbs of Beijing. The incised streams
are streams suffering channel bed erosion, such as the Duke, Marke, and Diaoga rivers. The aggrading
streams are the rivers with accumulated sediment deposition, such as the lower reaches of the Yellow
River, the middle and lower reaches of the Yangtze River, the Baishui and Bailong rivers in the upper
Yangtze River basin, and the lower Fujiang River. The streams with intensive bed load motion include
the Xiaobaini and Jiangjia ravines, and the Jinsha River.
Samples of macroinvertebrates were taken from these rivers and the biodiversity was assessed by
identifying the species from these sampling sites. Figure 11.3 shows the rivers and locations of the sampling
sites. The study was done before 2008 and a general relation between the biodiversity and the fluvial
process was obtained. In 2008 and 2009 the rivers in the Qinghai-Tibet Plateau were also studied and
samples were taken from 16 more sites in the source region of the Yellow, Yangtze, and Lancang rivers,
