shallow gully erosion

Steep hill slope erosion prediction model including shallow gully erosion supported by GIS, the process based hillslope erosion prediction model, and watershed erosion prediction model in China are outlined.

国内的侵蚀预报模型主要有在GIS支持下的陡坡地包括浅沟侵蚀的坡面侵蚀预报模型、有一定物理成因的坡面侵蚀预报模型和流域预报模型。

Results show that critical slope steepness of shallow gully erosion occuring is 18 °, and 40 metres in critical slope length, 650 square metre in runoff converged area.

结果表明，发生浅沟侵蚀的临界坡度约为18°，临界坡长为40m左右，临界汇水面积约为650m~2。

Soil erosion in hilly gully region of the Loess Plateau has clear sheet erosion zone, rill erosion zone and shallow gully erosion zone from watershed to gully edge.

黄土丘陵沟壑区梁峁坡面从分水岭到沟缘线土壤侵蚀明显表现为溅蚀片蚀带、细沟侵蚀带、浅沟侵蚀带。

The development regularities of water erosion on bare road embankment slope and bare cutting slope are gully erosion → shallow slip of slope and splash erosion → surface erosion → gully erosion → collapse respectively.

裸露的路堤边坡水力侵蚀发生发展规律一般为：沟蚀→边坡滑坍；

As slope length increased on hill-slope in a shallow gully catchment that has been destroyed for 15 years, soil erosion intensity tended to increase;

在植被破坏15年的裸露休闲地浅沟集水区，侵蚀蚀强度随坡长的增加而增加，且浅沟槽侵蚀量大于浅沟间，切沟沟槽侵蚀量大于切沟间。
