Based on analyses of the characteristics and causes of soil and water loss in Quanzhou city

Fujiang province

it is clear that the frequent typhoon and rainstorm

and geographical characteristics of mountain and hills

are the strong potential erosive power.The low resistant erosion ability of ground substance

especially the development of granite weathering crust is the inner cause of severe soil and water loss.And the human unreasonable land use

such as vegetation dest ruction

slope land cultivation

cultivation down the slope and the basic economic constructions

is the primary causes of soil and water loss.It is necessary to reconst ruct slope land

and carry out soil and water conservation tillage measures. What is more

comprehensive control in the small watershed as a basic unit is needed in order to control soil and water loss effectively.
