Environmental Risk Study of the Yuanjiang-Lishui River Basin in the Enshi Area

Abstract. The Yuanjiang-Lishui River Basin in the Enshi Prefecture is located in the southwestern part of Hubei Province, China. It is an important tributary of the Qingjiang River Basin and falls within the secondary region of the Qingjiang River Basin. The total area of this basin is approximately 5,320 square kilometers, with most of the region falling under the administrative jurisdiction of Enshi Prefecture. This paper investigates the environmental risks faced by the Yuanjiang-Lishui River Basin in Enshi Prefecture, conducting an in-depth study and discussion of the existing environmental issues in the region and their causes. The study reveals that the Enshi area of the Yuanjiang-Lishui River Basin currently faces significant environmental problems, including severe flood disasters, an increasingly acute conflict between the supply and demand of water resources, and water pollution.
