Based on the analysis of sedimentation and runoff data from main control stations on the main stream of the Yalong River, it is concluded that the section from Luning to Xiao deshi is the main sedimentation formation area in the Basin; especially after 1982,frequent human activities lead to sedimentation increase by 34.

With the development of dam system works in gully construction, a certain quantity of “wetland”indications in gully have occurred in the area of sediment yield from base rock of loess plateau.

Test of runoff and sediment yield regularity on slope farmland;

Characteristics of typical rainstorm,flood and sediment yield in Luoyugou Watershed;

Impacts of land cover change on runoff and sediment yields in the headwater areas of the Yangtze River and the Yellow River,China;

Experiments of artificial simulation setting water on initiation and sediment of man-made debris now - taking Shenfu-Dongsheng minesite as an example;

In order to find out the rule of runoff and sediment and the benefits of soil complemental irrigation in south Ningxia’s mountainous areas, so as to serve its ecological environment restoration, standard runoff fields were set up at Daping Experimental Station for Soil and Water Conservation in Xiji county, Ninxia.

However, there are few researches on the influence of native communities on the runoff and sediment in this region.
