【 摘 要 】

Toposequence and fertilizer are two important factors which affect the changes of soil chemical properties. It is meaningful for studying the spatial variability of soil chemical properties, especially soil nutrients, such as soil pH, available phosphorus (P), exchange potassium (K), exchangeable calcium (Ca) and exchangeable magnesium (Mg) in the hilly area with different toposequence and bunding systems. Changes of soil chemical properties under different toposequential positions or fertilizer treatments were discussed. Factors that affect soil chemical were proposed in addition to guide agriculture production. This review would provide guidance of soil nutrients management and soil improvement and crop production.
