土壤发生层

SOTER属性数据库包括图斑信息表、景观环境数据表、典型单个土体数据表和土壤发生层数据表。

The SOTER attribute database consisted of four parts ; the map delineation information table , the landscape environment table , the typical pedon table and soil horizon table .

剖面形态的差异表现为土壤发生层的不同，理化性质的差异主要表现在表土层。

The differences on profile configuration are soil genetic layers , and the differences on physico-chemical properties are topsoil layer .

最重要的土壤因子是土壤发生层厚度。

Among the soil Characteristics , soil depth is the most important .

土地利用变化引起的土壤耕种、栽培、施肥和排灌制度的变化，改变着土壤成土过程，从而对土壤发生层质量演化产生直接影响。

The changes in soil tillage , cultivation , fertilization , irrigation and drainage activities related to land use may make some pedogenetic processes disappeared and bring in other new processes which will affect the soil quality and soil genetic layers directly .
