Abstract:Artificial introduced plants played an important role in alpine and sandy vegetation reconstruction and recovery. Research on these artificial plant communities has helped in the development of sand-fixing mechanisms and ecological improvements; especially in the optimization of adaptive vegetation species. From 2008 to 2017, we selected 11 artificially transplanted species in the east sand area of Qinghai Lake to study. Vegetation sample surveys were performed every summer, and plant growth and community forming features were calculated and analyzed with the following three main results:(1)The majority of species, with the exception of Tamarix chinensis and Potentilla fruticosa, showed high survival rates above 80 percent and conservation rates of over 50 percent through the entire study period. Some species, e.g., Hippophae rhamnoides, Salix cheilophila, Pinus sylvestris, Populus simonii, and Hedysarum scoparium, with their fast-growing heights and canopy diameters, exhibited strong adaptability to alpine-sand ecology. Also, the coverages of all plant communities increased significantly, at a rate of 6.4 percent to 8.8 percent a year, with obvious benefits to the recovery of the sand ecosystem. In species diversity, Caragana korshinskii, S. cheilophila, H. scoparium, and P. simonii all had a relatively high diversity indexes including the Simpson's index, the Shannon-Weiner index, the Margalef richness index and Pielou evenness index. H. rhamnoides and P. sylvestris had remained dominant and constructive in the plant community.(2)The first three to five years were key to plant survival and growth. This period also displayed rapid growth of the forming community and increasing plant diversity.(3)H. rhamnoides, S. cheilophila, P. sylvestris, H. scoparium, and P. simonii should be selected as pioneer species to control desertification and recover plant ecosystems because of their strong benefits in terms of wind-sand prevention and soil amelioration. Other species could be subsidiary plants during vegetation reconstruction and recovery in all alpine-sand areas.
