Abstract:

In order to understand and discuss the structure, organization level and stability about plant communities plant community structure of desertification land control in Tibet, the species diversity is analyzed in Shannan National Comprehensive Demonstration Area for Desertification Control and Prevention in Tibet based on the investigation of 20 sampling plots. The results show that there are 34 species of plants about the Shannan National Comprehensive Demonstration Area of Desertification Control and Prevention in Tibet, among which the dominant species are Artemisia wellbyiHedysarum scoparium Morus albaAstragalus adsurgens and Artemisia desertorum. In the comprehensive demonstration area, the average coverage, height and density of sand-fixing plants were 31.6%±13.1%,41.2±19.9 cm and 4.6±4.7 plants·m-2, respectively; the average of Shannon-Winner species diversity indices was 0.99±0.54, the average of Simpson species diversity index was 2.55±1.37, and the average evenness of species was 1.76±0.75.

Key words: growth status, species diversity, plants community, desertification control and prevention comprehensive demonstration area
