Ripping is one of the basic measures for grassland improvement, and its intensity a key link in the process. Ripping is greatly significance for the sustainable management of grassland sustainability. The available studies have mainly focused on the impacts of the ripping on the plant community structure and productivity, while the response of plant community and soil moisture to the ripped intensity is still unclear. In order to explore the impact of the intensity of grassland ripped (27.4%, 46.3% and 61.9%) on the species richness, biomass and soil moisture of plant community, grassland ripped experiments were carried out in the typical steppe of the Loess Plateau. The results showed that the ripped intensity significantly affected the biomass of the plant community, species richness and soil moisture. The species richness of the ripped belt was significantly lower than that of the unripped belt by 1-3 species/m² under three ripped intensities. Compared with the whole area, the similarity of plant community in the ripped belt was lower by 23.85%-119.23%, while the unripped belt was lower by 44.43-84.55%. The aboveground biomass (AGB) of the ripped belt, unripped belt and whole area all increased with the increase of species richness and aboveground biomass was negatively correlated with Simpson index and Shannon Weiner index. When the ripped intensity was 27.4% and 61.9%, the AGB of the ripped belt and the unripped belt decreased with the increase of soil moisture. The belowground biomass (BGB) and total biomass of each ripped intensity were significantly negatively correlated with soil moisture. The BGB of the unripped belt under three ripped intensities was 88.2%-134.6%, 52.4%-67.8% and 2.5%-16.6% higher than that of the ripped belt, respectively. The biomass was 103.9%-152.9%, 59.3%-75.8% and 9.1%-22.6% higher than that of the ripped belt. The species richness and AGB of the plant community first increased and then decreased with the increase of the ripping intensity. When the ripping intensity was 43.7%-55.3% and 43.8%-45.7%, the species richness and biomass of the plant community reached the highest. The species richness, community similarity index, root-to shoot ratio and other indicators of the community were integrated to analyze the impact of ripped intensity on plant community diversity, biomass and soil moisture, and clarified the impact rule and mechanism of ripped on the characteristics of typical steppe plant community and soil moisture in this experiment. The results provide a scientific basis for the adoption of ripped measures to achieve grassland cultivation and restoration, and is of great significance for protecting grassland biodiversity and improving grassland productivity.
