However, in the process of governmental decision-making there are a considerable amount of hidden-agendas at the grass-roots level which are resulted both from objective and subjective factors.

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.

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.

Decomposition and nutrient release of fine root in Alnus formosana woodland covered with two herbages(Lolium multiflorum lam and natural grass) as well as mixed decomposition of grass root and fine root in woodland with intercropping system of Alnus formosana and Lolium multiflorum lam was studied by buried bag experiment at Danling county in Sichuan province last year.

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.
