Theme 1: Grassland Ecology
Description
The availability of nutrients for the grassland ecosystem is significantly influenced by changes in soil enzyme activity brought on by precipitation. Soil enzyme activity is an essential element controlling soil nutrient supply. This study used the Inner Mongolian desert steppe as its research subject and examined how different soil enzymes—urease, alkaline phosphatase, and invertase reacted to changing precipitation levels. According to the typical quantity of long-term precipitation in the area, four gradients of precipitation were established: 50% reduction (P1), control (P2), 50% increase (P3), and 100% increase (P4). First, the findings revealed that rising precipitation can boost invertase and alkaline phosphatase activity. Second profound soil chemical action is lower than surface soil protein action, expanded precipitation likewise advanced the exercises of urease. Third, the related examination results showed that there were huge negative connections among's urease and nitrate nitrogen, soluble phosphatase and all-out carbon, and accessible phosphorus, while there was a positive relationship among invertase and accessible potassium. In light of the outcomes previously mentioned, we can presume that the difference in precipitation can advance the exercises of invertase, soluble phosphatase, and urease in the soil, and direct the stock degree of carbon, nitrogen, and different components in the soil of desert steppe. Uncovering the characteristic connection between environmental security, precipitation design change, and soil supplement supply in a desert steppe is of extraordinary importance.
