Plant quantitative characteristics (QC, namely height, coverage, and standing crop), leaf functional traits (LFT, namely leaf area, leaf dry matter content, and specific leaf area), and CSR strategies (competitive, stresstolerance, and ruderal strategies) represent the product of plant resource investment and allocation in specific environments. Quantifying how grazing influences these strategies is essential to understanding the mechanisms that sustain desert steppe ecosystems. Using a long-term grazing experimental platform in the desert steppe of Inner Mongolia, this study systematically examined the effects of different grazing intensities-no grazing (CK), light grazing (LG), moderate grazing (MG), and heavy grazing (HG)-on QC, LFT and CSR strategies from a spatial perspective at community level, and further explored their relationships with soil properties. Results showed that increasing grazing intensity significantly reduced leaf area and specific leaf area while increasing leaf dry matter content, indicating a shift in plant strategy from resource acquisition to resource conservation and physical defense. The plant communities were predominantly S-strategy species. Spatially, the heterogeneity of LFT were greatest under MG treatment, while QC and CSR strategies were greatest under LG treatment. The difference in spatial heterogeneity further indicates a hierarchical adaptive mechanism. Soil properties, particularly nitrogen and phosphorus, were identified as key factors driving plant ecological strategies. Grazinginduced soil nutrient limitation forces plants to trade off growth for survival strategies.
