Abstract: Agroforestry is one type of the ecological agriculture. Using birds as indicators, the diversity and composition of birds were investigated by setting 9 sampling points in Ganjiabao Agroforestry Demonstration Sites, which is located in Lixian, Sichuan Province, from 2015 to 2017. The results showed that both richness and abundance of birds increased significantly after the land transformed to agroforestry system. The proportion of forest birds and bush birds, meanwhile, also increased. It suggested that the system of agroforestry could increase the diversity of birds, and thus contributed to the recovery of local biodiversity and the restoration of ecosystem significantly.
