soil conservation functions and service values of the afforested vegetation by enclosure at the Wufendigou experimental base in Huangfuchuan watershed were calculated.Results showed that the volume of controlled soil in the study area was 89.45 t/(hm2·a) and the total benefit of soil conservation was up to 77.09%.The sequence of vegetation type

in terms of the controlled soil volume from high to the low

was grassland

shrub woods

arbor woods

and bare land.The value of controlled soil per year was estimated to be as much as 856 780 yuan and the values of controlled soil nutrients

reduced land disuse

and reduced sediment were about 822 925

30 234

and 3 620 yuan

respectively.The sequence of vegetation type

according to the contribution of vegetation type from high to low

was shrub woods

bare land

grassland

and arbor woods.The value of controlled soil was 2 050 yuan/hm2 and the values of controlled soil nutrients

reduced land disuse

and reduced sediment were about 1969

72

and 9 yuan/hm2

respectively.According to the contribution of vegetation type from high to low

the sequence was shrub woods

grassland

bare land

and arbor woods.
