Soil organic carbon loss was mainly influenced by soil erosion intensity, appearing the same trend as did soil erosion intensity with increasing slope gradient.
Four different restoration communities (labeled as ecological restoration treatment I, II, III and IV) were selected by space-time replacement method according to the erosion intensity in degraded purple soil ecosystem.
Although erosion intensity was not serious in the study area, its environmental impacts should not be ignored because of great soil nutrient loss and coarseness of soil particles.
Pollen, geochemical and sedimentological data from Sidi Ali, a montane Moroccan lake, provide a 7000 yr record of changes in climate, catchment vegetation and soil erosion intensity.
Field studies and model experiments, as well as theoretical considerations, suggest that bed sediments represented by soil aggregates in overland flows on slopes exert a considerable influence on the intensity of erosion processes.
The capacity of the reservoir was found to be reduced by 28.8?Mm3 during this period and the annual average loss is calculated as 0.75?Mm3 (0.71%), indicating the intensity of erosion from the catchment zone.
The research indicates that mean soil losses within agricultural fields are 2 to 3 times higher than the tolerable soil losses for the area and that net soil export from fields is a poor indicator of the intensity of erosion within the field.
Attention has been paid to many pedological variables affecting intensity of erosion, but little to the influence of iron compounds on the type, size, shape and porosity of soil aggregates.
Soil organic carbon loss was mainly influenced by soil erosion intensity, appearing the same trend as did soil erosion intensity with increasing slope gradient.
Pollen, geochemical and sedimentological data from Sidi Ali, a montane Moroccan lake, provide a 7000 yr record of changes in climate, catchment vegetation and soil erosion intensity.
Soil nutrient loss increased linearly with increasing soil erosion intensity.

In this article,the author disscussed that the variability of soil erosion intensity on the loess plateau is verylarge,sometimes is very strong,and sometimes is very light in the endless geology periods firstly. Baased on theZiwuling example which soil erosion intensity from strong to light. and many soil and water conservationcomperihensive harness advanced modeds,it is explained that soil erosion of the loess plateau can be harnessedtotally.So only by soil and water conservation is it the major fundamenta...
From the view of the soil erosion,the basic geomorphic characters in Fujian Province are analysed.The effectsof the characters the rain erosivity,soil erosion modulus and soil erosion forms have been discussed.The prohibited25 slope has also been discussed.Finally,the paper concerns the characters of soil erosion under variouslandscapes land it is pointed that small basin hills with the black mica(r￣5)and purple shale(k2ch)and high densitypopulation are weak ecological zone and severe soil erosion in the pr...
