土壤类别

最后在GIS环境中实现不同母岩上发育的土壤类别空间可变性的数字化表达。

Lastly , geography information system ( GIS ) mapping to show Spatial Variability of the Soils digitally developed on different parent materials .

与不同分类系统中土壤类别归属作了参比，同时也与福建、江西山地土壤作了比较。

Comparisons were also made with the soils in the mountain regions in Jiangxi and Fujian in terms of attribution in the Chinese Soil Taxonomy and between attribution of the soils in different soil classification systems .

以耕层土壤质地类别作为制图单位，分为轻粘土、重壤土、中壤土、轻壤土和砂质土五种类型。

The soil were divided into five groups of soil , e , g , light clay , heavy loam , medium loam , light loam and sandy soil , using the group of soil texture of plowed layer as the mapping unit .

土壤侵蚀按照作用力类别可分为水力侵蚀、风力侵蚀、冻融侵蚀和重力侵蚀，其中水力侵蚀在我国是最为活跃的侵蚀类型，降雨是造成水力侵蚀的主要动力。

Soil erosion can be classified into waterpower erosion , wind power erosion , freeze thawing erosion and gravitation erosion .
