Laboratory triaxial compression tests were carried out in order to determine the stress-strain and strength characteristics of reinforced loess.

用三轴压缩试验方法研究了土工合成材料加筋黄土的应力－应变及强度特性，探讨了在各种不同加筋方式和围压下加筋机理。

In order to deeply understand biomass formation for Panicum virgatum in the semiarid loess hilly-gully regions, we investigated the biomass production, ramet generation, and resource supply and demand at the plot and tussock scales during the yearly life cycles of two switchgrass species, i.e. early-maturing and late-maturing ones, respectively.

为深入认识半干旱黄土丘陵沟壑区引种能源植物柳枝稷生物质生产的开发潜力及其约束机制，调查了农田、植丛尺度上早熟和晚熟柳枝稷年度生命周期内生物量累积、分株建成动态，以及土壤水分供求平衡过程。

In contrast,the unenclosed one is Artemisia sacrorum community,dominated by Artemisia sacrorum,Poa sphondylodes,and Potentilla acaulis.
