DISCUSSION ON THE INFLUENCE OF HUMAN DISTURBANCE FACTORS ON SOIL STATE

At present, along with the continuous improvement of the national economic living standard, and the increase in the scale of all kinds of production operations, the national environmental awareness is indifferent, which leads to the soil damage problem being particularly serious. Human disturbance had significant effects on grassland vegetation diversity, and human disturbance significantly reduced vegetation coverage, aboveground biomass, richness index and diversity index. Soil environmental change caused by human action is a sign to measure and reflect the quality of soil resources and environment, which is closely related to global change and sustainable development.
