    摘要:

    山西省位于黄土高原东部;与黄土高原西部有很大的差异,主要表现为境内多山,而又多山间盆地。吕梁、太行两山系,约作南北向贯穿全省。山边均有不同高度的黄土丘陵及黄土阶地,组成高原特征;在两山系间由于陷落关系,形成一系列大、小不同的地塹式盆地,亦约作南北向罗列,仅南端偏西,北端略偏东而已。这些盆地再被东西向山地分割,因而形成互不相联的分割盆地,如大同盆地与忻定盆地为雁门关(鳗头山)山地分割。

    Abstract:

    Shansi province is situated in the eastern part of loessial plateau and characterized by a set of tectonic basins surrounded by mountains and hills. The river siftings in these basins which serve as the main soil forming materials form gentle flat topography. Owing to the variation of textural profiles and other genetical factors, different types of saline soils are formed: 1. The spotty saline soils: The characteristic parent materials in the basins are interbedded layers of light (sandy) and heavy (clay) sediments;variation in micro-relief occurs, as caused by shifting of river courses, and the depth and the degree of mineralization of ground water are frequently variable. As a result, saline soils with various degrees of salinization and salt constitution in spots scattered among the cultivated land of non-salinized lieht meadow soils.
