- Abstract:
-
The vegetation communities of activating dune in the Minqin oasis-desert ecotone were investigated by a conventional way for researching the plant species structures and characteristics in different position of the dune. The results showed that there is a different plant community type in each position of the activating dune from low, midst, dune tops and midst, low of slope depressions and sandy land among the dunes. The differences of plant species and quantity had exist, also the variance of plant communities obviously. There is only annual grass species on dune tops, but shrubs on sandy land. The bio-diversity and the similarity index of communities showed that the difference of ecological factors not only affected the distribution patterns of species, but also changed the structures and functions of plant communities. The vegetations of these activating sanddunes are simple and suffer degeneration serious, then need enhanced protection methods to prevent sand dunes from becoming mobile.
