英文摘要

Gypsum outcrops of southeastern Spain (Almeria) have been highlighted as the most outstanding for the conservation of Iberian gypsum flora by flora rarity and richness, as vascular as cryptogamic plants. However, plant community distribution patterns according to soil chemical properties have been little studied in these gypsum areas. Spatial distribution pattern of plant communities in gypsum hills and its relation to soil chemical properties was surveyed in this study. Twenty-one plots (5 x 5 m) were settled along a semiarid gypsum gradient in Rio de Aguas Basin. Soil samples were taken from each plot’s superficial layer for chemical analysis. Plant canopy cover was sampled at species level. Three plant community bands are identified (from bottom to top) as level I (Flat Piedmont Zone), level II (Hill Slope Zone), and level III (Hill Top Zone). Gypsophyte species (mainly found in level II) appear to be specifically adapted to nutrient-stressed environments (high sulfate content and deficiency in some soil nutrients). Nutrients play an essential ecological role in determining species distribution and community composition. Since this area is a very important site for extracting very high quality gypsum, the pattern described here can be used as a useful tool for ecological restoration of gypsum quarries. Considering environmental heterogeneity of gypsum areas (as an "ecosystem of reference") is crucial for a successful ecological restoration.
