soil erosion distribution

Soil erosion spatial distribution were identical with Hainan landform . 8.

土壤侵蚀量的空间分布与海南中问高,四周低的地形构造一致.

The seepage and erosion are primary dynamic influence factors on bank failure; and the soil composition, soil distribution and slope angle of bank are primary internal influence factors on bank failure.

指出了坡内的渗流作用与坡前水流的冲刷作用是岸坡发生崩塌的主要动力因素，而岸坡土体的物质组成和分布、岸坡坡度等则是岸坡发生崩塌的主要内在因素；

The spatial distribution of soil erosion abided by the law that soil erosion lightened from the south-east foothill-plain to the north-west upland-mountain area in 1980's, the opposite way round in 1990's.

在空间分布上，土壤侵蚀呈现出20世纪80年代由东南低丘平原区向西北丘陵山地区减缓，而90年代呈相反的规律；

According to erosion vertical zone distribution in the loess hilly and gully region, the methods for demarcating distribution slope location of soil erosion patterns at small watershed are put forward.
