1, Based on the quantification theory, the stability assessment model of rock debris slopes are presented.

2, It is argued that application ofthe quantification theory to the correlation study of crops traits is feasible, and the methods of its adoption are proposed.

3, Self-check coincidence rate of the discriminatory equation and values based on quantification theory exceed 85%.

4, We propose a modeling method of artificial psychology which based on Quantification Theory I and introduce how to apply it in recommender system in this paper.

5, Therefore taking into account of the attributes of the current indices, quantification theory is adopted to give the rocky surrounding rock quantitative evaluation.
