A multiple regression equation is established and used to study the soil sensitivity.

Aiming at the hilly region of red soil with vulnerable ecosystems and supported by the RS and GIS,this study establishes a soil erosion sensitivity evaluation information system database for hilly region of red soil.

As the study on soil erosion prediction before was not fit for the modern requirements of sustainable development of resource and environment, the research on soil erosion sensitivity becomes important.

The percentages of the areas with different soil erosion sensitivity varied with the strength of the affecting factors.

Guided by the Universal Soil Loss Equation and the unique geographic features of Ji nan City,primary evaluation factors for the sensitivity of soil erosion in Ji nan City are determined,including precipitation,terrain undulation,soil quality,and vegetation.

Application of GIS technology in the evaluation of sensitivity to soil degeneration;

Characteristics of soil humic acid dissociation and its complexation with copper;

In order to investigate the mechanism of CPR improving soil, the effects of CPR on the soil humic acids (HAs) were studied by nuclear magnetic resonance spectrometry in the black soil with incubation experiment.
