- Abstract:
- Field survey and laboratory experiment were conducted to study the characteristics of the soil seed bank in terms of species density, composition, diversity and similarity over different erosion zones on abandoned land in the hilly-gullied Loess Plateau region. In this study, 26 species belonging to 13 families and 24 genera germinated in different erosion zones. Compositae and Granimeae are the main species in different erosion zones which have different species composition. In 0—10 cm soil layer, the density of soil seed bank changes with erosion zones, it reduces first, then increases and finally sharply decreases. Diversity index, richness index, evenness index and ecological dominance of the soil seed bank are different among different erosion zones, but there is no significant correlation. The species similarity index of soil seed bank composition ranged from 0.40 to 0.82. The similarity index reduced with the increase of the distance between erosion zones. It indicated that soil seed bank in different erosion zones was redistributed by slope runoff and sediment transportation. This process includes seed removal and deposition with flow on the slope.
