That class, acts as a key role of society, is called the“grass-roots estate”.

The experimental results show that the adsorption of Pb and Cd by sod layer soils could be described using Langmuir and Fruendlich isotherms with the correlation coefficient significant at the confidence level of p=0.

Study on grassroots-reinforced soil by laboratory triaxial test;

Experiment investigation on reinforcement mechanism and strength criterion of grassroots reinforced soils;

This paper researches in the restriction and self-discipline of information cultural ethics,as well as the control of information sources transmission and content from the perspective of grassroots.

Fine root and grass root decomposition and nutrient dynamics in an intercropping system of Alnus formosana-Lolium multiflorum

On the basis of the research of the fine root of the Betula luminifera-Hemarthria compressa compound mode and grass root biomass in Hongya county,Sichuan province,we discuss the underground spatial distribution pattern of this mode.

This study aims to investigate the rate of mass loss and release of nutrient elements of fine root and grass root in plantation of Triploid Populus tomentosa and Lolium multiflorum established on an abandoned farmland at Tianquan County in Sichuan Province.

As a primitive modality of culture,“grass-roots culture”in China which can be found existing in a particular form in Chinese society has its certain colony.
