Based on the continuous observation data for many years from 2016 to 2019, this data set makes a detailed investigation on the community structure and diversity, and collects soil data. For the obtained soil data, the soil total nitrogen, organic carbon, available phosphorus and available potassium were measured, and the weight of live animals and the light and dynamic monitoring of dominant plants were monitored. This data set provides basic data for grassland resource evaluation, desertification grassland management, restoration and sustainable utilization evaluation.
