Abstract: The hilly areas of central Sichuan Basin are located in the upper reaches of the Yangtze River. The stand in these areas is an important component of the ecological barrier for the upper reaches of the Yangtze River. The Shrub and grass layers as an indispensable part of forest ecosystems have a great function on improving the interception of runoff and maintenance of biological diversity and conserving water and soil. In this paper,the main stand types (mixed alder and cypress plantation and pure cypress forest developed from mixed alder and cypress plantation) are used as the study objects,and researches are conducted on the species diversity of shrub and grass layers under the mixed alder and cypress plantation. These results will provide a theoretical basis for the species diversity conservation and the healthy management of artificial cypress plantations in these regions and similar areas.
