1) organo-mineral complex
有机矿质复合体
1.
Soil organo-mineral complexes were separated from steppe soils sampled before and after grassland degradation using fractional method of particle size and density, and humus of different combined forms were extracted from these complexes,then variations of humus content, distribution and composition were analyzed respectively.
草原退化引起的土壤性质的变化会影响腐殖质与矿质颗粒的结合状态 ,本文对采自草原退化前后的土壤样品分级提取不同粒径的土壤有机矿质复合体 ,然后用不同的浸提剂提取复合体中结合状态不同的腐殖质 ,对其含量、分布和组成在草原退化前后的变化进行了分析 ,得出了土壤各粒级复合体中腐殖质主要以松、紧结合态形式存在 ,并且主要集中在粘粒和粉粒级复合体中 ;草原退化时土壤腐殖质的减少主要是粘粒细粉粒级复合体 ,其次是粗粉粒级复合体中松态腐殖质减少的贡献 ;而松态腐殖质的减少又主要是 HA的减少等结

Soil organo-mineral complexes were separated with fractional method of particle size and density from steppe soils, one degraded and another recovering.
从退化草原恢复前后的土壤样品中,提取各粒级土壤有机矿质复合体,用不同浸提剂提取表征不同结合状态的腐殖质,对其含量、分布和组成在草原恢复过程中的变化进行了分析,得出了土壤各粒级复合体中腐殖质主要以松、紧结合形式存在;它大部分分布在粘粒和粗、细粉粒级复合体中;草原恢复时土壤腐殖质的增加主要是粘粒和粗、细粉粒级复合体中松态腐殖质的贡献,其次是稳态腐殖质;而松态腐殖质的增加主要是HA 的增加,稳态腐殖质的增加主要是FA 的增加。
