The absorbing capacity of six kinds of soil development from loess parent material in Qinghai was studied by using of Cr(III) stardard solution and the effects of soil organic matter,cation exchange capacity(CEC) and physical clay on the absorbing capacity of Cr(III).

The research demonstrated that Cd highly concentrated assumes the punctual distribution,its distribution situation is been limited by the parent material,the high content in soil mainly caused by the human factors.

In the eyes of geology, soil formation in one of the geological events that occurred during Quaternary period, According to some data of Quaternary geology, archaeology and histori-physical geography, we studied the formative stages of different soil parent materials, showing that soil age have much difference in Shandong area: The age of old relic soil is over hundred thousands of years.

There was a very important relation between fertility quality of the soil and soil parent materials, topographical environment, landscape position.

pH and the exchangeable aluminum content in acid soils as affected by parent materials and cropping systems;

Comparative study of red earth grain-size from different parent materials in Zhejiang Province;

The characteristic of soil geologic environment of Lanzhou such as tectonic, dynamic geologically functions, geomorphic, climate, soil parent materials were studied, the effects of the soil geologic environments on the features of the soil of Lanzhou were analyzed.
