Abstract: Biodiversity database information system is the basis for evaluating biological diversity. Up to now, the existing biodiversity data of Sichuan Province have not been well integrated, and, due to the lack of the information about the spatial distribution of the species, the existing data are difficult to meet the environmental impact assessment. In this paper, we established a biodiversity database information system of Sichuan Province by the integration of the data of existing biodiversity, Ganzi terrestrial and aquatic biodiversity, environmentally sensitive areas in Sichuan Province, and biodiversity on-site survey. Through the development of the database and network, it’s realized to search for and reveal the spatial and attributive data of biodiversity to provide references for environmental management and environmental impact assessment.
