Abstract
The soil and water conservation sloping face achievements of benefits of
runoff & sedimentation reducing regularity and guideline system are builded
by using series of multiyears flow-off the same time,Two calculation
method of hydrology and soil and water conservation are pared by using
sift data of land use and typical investigation. The disciplinarian of runoff
& sedimentation produce are discussed and the achievements of benefits of
runoff & sedimentation reducing of The QIUSHUI river are analysed especially
in soil and water conservation main results of this paper are as
follows:
(1)Based on hydrology station of QIUSHUI river,The rainfall data are
disposed in series and typically formula of rainfall、flow-off
and sediment are builded,. hydrology statistical as
rainfall~flow-off model、rainfall~sediment model and flood~sediment model.
Flood flow and flood sediment are specially analysed by using such as
different series contrastive method and curve of double cumulate method and
formula of experience method.
(2) The method of “sediment counting by using flood”is improved on “soil
and water conservation method”.Based on analysing the data of microplot,the
flood reducing guidelines system of QIUSHUI river sloping face are builded.
The Achievements of benefits of runoff & sedimentation reducing in 90 age of
QIUSHUI River are analysed and calculated.

(3)The calculate results of “formula of experience method”and “soil
and water conservation method”are distinction of this two
methd are indicated.
(4)The large region soil and water conservation actions are advised, the
deficiencies and amelioration methods of the research are indicated.
