土壤形成和发育
7.1 Soil-forming factors and its functions
土壤形成因素及其在土壤发生中的作用
7.2 Pedogenic processes
Zonal soils: soil varied with latitude according to climatic and
vegetation conditions.
Intrazonal soils: soils were more closely associated with parent
organic matter accumulation
（pedogenic processes）
Parent material is main mineral sources of soil formation, and its nature is fundamental to many soil characteristics.

➢成土因素具有同等重要性和不可替代性
The soil-forming factors operate in combination. It is no tpossible to rank them in order of importance – they are all equally important, although within any one environment certain factors may have a more dominant influence on soil formation than others.

The operation of pedogenic processesis controlled by a number of environmental factors operating through the medium of time and that these determine the type of soil produced in any particular location.

The influence of environment factors on soil formation was considered in a more systematic manner following the work of Jenny(1941).

地带性土壤（Zonalsoils）
At the regional and global scale, climate and biota will have a dominant influence on soil formation, and soil types can be related in general terms to bioclimatic zones. The remaining factors will then account for variations in soil formation within a particular bioclimatic zone.
