摘要：This study attempted to find consistent relationships between climate, latitude, and the richness of plant species on sand dunes. The richness of plant species on sand dunes in the Northern and the Southern hemisphere decreased with latitude or increased with air temperature. This suggests a latitudinal gradient of vascular plant richness on sand dunes in both hemispheres. However, the relationships between the richness of coastal plant species and mean annualprecipitation were not statistically significant in either hemisphere. There is a vital need for construction of sand dune parks having conservation programs.
