Species Composition and Spatial Pattern of Understory Herbaceous Plants on an Ecological Rehabilitation Site from Open Coal Mining
A patch of open coal mining land was reclaimed for ecological rehabitation 17 years ago in Antaibao, Shanxi Province, China. Under the rehabilitated Robinia pseudoacacia + Pinus tabuliformis mixed forest, herbacious plants in 320 quadrats (1 m x 1 m) in the 0.8 hm2 plot were surveyed for the species composition, spatial patterns and other community properties. The results showed that the land was rich in herbaceous species, containing 44 species, which belonged to 30 genera under 16 families. The dominant families were Poaceae and Asteraceae, and the dominant species included Artemisia annua, Elymus dahuricus and Artemisia sieversiana. The initially planted Bromus inermis deteriorated badly. The important value, species abundance and frequencies were different among the families or species. The dominant families and species were commonly distributed, and the spatial patterns were obviously spatial heterogeneous. Fig 4, Tab 2, Ref 31
