The level analysis is the modern and new method to analyse and dia- gnose a system

which is a combination of qualification with quantifi- cation.When analysing Beihe small watershed systematically we cluster and group all the factors and establish models of level analysis.The ana- lysing results show that the effecting extent of nine factors to environ- ment worsenning of the watershed

soil and water loss and poorness of economy could be lined as

condition of land utilizationsoil texture climatic conditionvegetation conditionanimal resourceresoure of labour powerculture and educationgeomorphorlogical typegeological tectonic.Thus

it is suggested

firstly

to adjust the proporiton of lands for farming

forestry

husbandry and sideline production

to improve soil structure and raise land productivity

meanwhile

to construct ins- tallations of water conservancy

to accelarate greening and to enlarge vegetation when drawing up harnessing plan.
