摘要

于2005年在内蒙古准格尔旗西召沟小流域进行了野外调查、采样及室内土壤有机质含量测定试验。结果表明

种植沙棘柔性坝的沟道土壤有机质含量远远大于未治理的对比沟

从而证实了沙棘柔性坝具有显著地提高沟道的土壤有机质含量

改善沟道土壤肥力生态效应。土壤有机质含量具有-定的垂向变化

大多数情况下表层土壤的有机质含量高于中、下层土壤;沟道及沙棘柔性坝的土壤有机质含量在纵向大致呈现由上游到下游缓慢递增的过程。沟道土壤有机质的这种纵向变化规律与沙棘植物柔性坝拦沙淤积厚度纵向变化规律相同。

Abstract

From the samples collected in field

in Xizhaogou wa tershed in Inner Mongolia

China in 2005.Soil organic matter content is measured in laboratory.The result indicated that the soil organic matter content in the gully with seabuckthorn flexible dam is much higher than that without the flexible dam.The flexible dam has the notable ecological effects of improving soil organic matter content and soil fertility in gully.At the same time

the result shows that soil organic matter content has a certain vertical variation

but the maximal value occurs in the surface soil layer in most cases.Soil organic matter content increases gradually from upstream to downstream in the gully with seabuckthorn flexible dams and in the dam body.This change is similar to the longitudinal change of sediment thickness in the gully with dams.
