native soil

Organo-mineral complexes were separated from different developing direction and phases of steppe soils with fractional method of particle-size and density, and their mounts, humus contents, composition and ratio of carbon to nitrogen were analyzed.

对采自处于不同发展方向和阶段的草原土壤分组提取有机矿质复合体，并对它的质量分数、腐殖质质量分数和组成、Ｃ／Ｎ比值等的变化做了分析，试图从土壤复合体变化的角度去认识草原的退化和恢复过程。

Five different land utilization methods of saline steppe soil in the west of Jilin province were selected,including grazing grassland,fencing grassland,tillable,new paddy field and long-term cultivate paddy field.

结果均揭示水田和围栏草原土壤肥力质量较高,而放牧草原和旱田土壤肥力质量较低,呈退化趋势。
