Soil profiles have the obvious diagnostic horizons and properties and characteristics of soils have distinct change along their profile depth under stable conditions of soil development.
在稳定的土壤发育条件下，土壤剖面有可以鉴别的诊断层，其中一些性状特征沿剖面分异明显。
Results showed:The soil organic carbon, nitrogen and microbial biomass C? N of different kinds of wetlands were obviously differences, and decreased with increasing depth at profiles.
结果表明：不同类型湿地土壤碳、氮和微生物C、N有明显差异，而且均随深度的增加而降低。
The model can predict not only the soil water dynamic profiles and the soil water potential profiles, but the changes of the effective root density with depth and time.
该模型除能预报根系吸水的一些水分动态和水势动态外，还能预报有效根密度的时空变化。
