黄土湿陷特性的分区是在总结和分析不同行业的湿陷性分区成果基础上，结合公路工程建设特点进行了黄土地区公路湿陷性分区。

To saturated and soft loess foundation , the poprote ratio and deformation is big, the compressibility is high, the strength is low, the time before it steady is long.

本文针对西安地区的工程地质问题，重点论述了湿陷性黄土地基和饱和软黄土地基的特性及地基处理方法。

The paper discusses interaction of Cr and As with nutritional element: Ca, Mg, P and finds that Ca and Mg have decrease absorption of loessial soil to Cr and have increase to As.

初步发现钙、镁对黄土吸附Cr有减小作用，对吸附As有增大作用；Cr和As同时存在时，似乎在黄土中的吸附量有相互促进趋势。

By the infiltration test of soil column, the author concludes that Cr and As has the following migration patterns by dynamic researches. 1 The absorption and migration of Cr and As in loessial soil relate to content of mucilaginous grain.

4通过土柱淋滤试验，从动态角度研究得出铬、砷在黄土中具有以下迁移规律及特点：①Cr、As在黄土中的吸附和迁移与土壤中的粘粒含量有关。

The Holocene loess-soil sequence on the Chinese Loess Plateau constitutes an excellent record of evolution of soil formation, monsoonal climate, eolian dust accumulation and influence of arable farming of over 10000 years.

At the same time, on the base of the analysis and study of the characteristic of sliding stability failure of loess slope in Sanmenxia area, a method, which is suitable for many hori

同时，在对三门峡地区黄土边坡滑动失稳特征进行分析研究的基础上，采用了一种适合多种土层、不同坡型的边坡稳定性分析方法，对三门峡地区四处深路堑黄土边坡实体工程稳定性进行分析及评价。

Hilly gullied loess region, the main body of Loess Plateau, is also an eco-economic sensitive area with special landscape pattern.

黄土丘陵沟壑区是黄土高原的主体部分，也是具有特殊景观格局的生态-经济敏感区。

To construct large rainwater collecting and storing projects in line with local conditions in gullied rolling loess area of the Loess Plateau can effectively utilize the rainwater resources and provide services for soil and water conservation measures and production and life of the local people.

在黄土高原的黄土丘陵沟壑区因地制宜建设大型雨水集蓄工程，可有效利用雨水资源，为水保措施和当地群众的生产生活服务。

Haiyuan county belongs to mountainous region of Longzhong loess hilly gullied region in the loess plateau,and there are seven kinds of geological hazards types existing in Haiyuan county ,including soil erosion and water loss,landslide,breakdown,mud rock flow,unstable slope,ground collaps and ground fracture etc.

海原县地处黄土高原，属陇中山地与黄土丘陵区，主要地质灾害有水土流失、滑坡、崩塌、泥石流、不稳定斜坡、地面塌陷和地裂缝等7种类型，以及人类工程经济活动引起的地质灾害类型。

The ecological environment of the Loess Plateau was warmer and moister than it is today, there was more luxuriant vegetation, and the forest land occupied about 25 % of the entire Loess Plateau.

黄土高原的生态环境较当今温暖湿润，植被更为繁茂，林地约占整个黄土高原面积的25%。
