Cleistogenes songorica, as a clustered grass, is the main grassland flora of the Stipa breviflora desert grassland. Some studies have shown that the constructive species of S. breviflora (sparse cluster type) is prone to cluster fragmentation; however, research on C. songorica is relatively rare. Then will the C. songorica plant population (dense cluster type) also have cluster fragmentation under the influence of intense grazing? To answer this question, we used variance analysis and geo-statistical methods. The spatial distribution of C. songorica in S. breviflora desert steppe in Inner Mongolia was measured under four grazing intensities (no grazing, CK, 0 sheep center dot ha-1 center dot half year-1; light grazing, LG, 0.93 sheep center dot ha-1 center dot half year-1; moderate grazing, MG, 1.82 sheep center dot ha-1 center dot half year-1; and heavy grazing, HG, 2.71 sheep center dot ha-1 center dot half year-1) and four scales (10 cm x 10 cm, 20 cm x 20 cm, 25 cm x 25 cm, 50 cm x 50 cm). We then analyzed C. songorica whether fragmentation was present. The results showed that increased grazing intensity is associated with increased density and decreased height, coverage, and standing crop of C. songorica. The spatial distribution of C. songorica was affected by structural factors, and spatial heterogeneity decreased with increased spatial scale. With increased grazing intensity and spatial scale, the patch area of C. songorica gradually increased and tended toward band distribution. In summary, increased grazing intensity and spatial scale led to weakened heterogeneity of C. songorica spatial distribution and increased consistency. Heavy grazing led to the fragmentation of Cleistogenes songorica. With increasing grazing intensity and spatial scale, the patch area of C. songorica gradually increased and tended toward a band distribution. As grazing intensity and spatial scale increased, the heterogeneity of C. songorica spatial distribution weakened and consistency increased.image
