Abstract
Patchy distribution of plant populations is a hallmark of saline grassland ecosystem at Weiyuan, YouYu County, Shanxi Province, north China. According to species composition and community dominance, the grassland was divided into 8 patches. First, we investigated and analyzed community characteristics, including α diversity and soil properties (soil moisture, bulk density, pH value, basicity) of the 8 patches of the grassland and found that the 8 patches were obviously divided into 2 categories. Patches I, II, and III formed group 1, and the other patches were included in group 2. The soil moisture, bulk density, pH value, and basicity in group 1 were lower than those in group 2 (p
