摘要

以皇甫川流域五分地沟试验区为背景

运用相关手段和方法

对其土壤保持功能和服务价值进行了研究。(1)研究区土壤保持量已达到89.45 t/(hm

.a)

总的土壤保持效率达到77.09%。按从高到低的排序依次为:草地>灌木林>乔木林>无植被地。(2)每年保持土壤价值为856 779.59元

其中保持土壤养分价值为822 925元

减少土地废弃价值为30 234元

减轻泥沙淤积价值为3 620元。植被类型的贡献顺序为:灌木林>无植被地>草地>乔木林。(3)研究区按单位面积的土壤保持价值量为2 049.71元/hm

其中保持土壤养分价值为1 968.72元/hm

减少土地废弃价值为72.23元/hm

减轻泥沙淤积价值为8.66元/hm

植被类型的贡献顺序是:灌木林>草地>无植被地>乔木林。

Abstract

By using the related methods

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

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.
