水电是四川最大的能源优势,老、少、边、穷地区占四川幅员面积最大,以开发老、少、边、穷地区的水电资源为龙头,带动和推进该地区经济的发展,这是近几年通过实践摸索出的一条成功之路,是四川经济发展战略中一个带全局性的关键问题。四川有大小河流1419条,绝大多数发源于川西北高原和盆周山区,以巨大落差流向东南,汇入长江。 Hydropower is the largest energy advantage in Sichuan. Old, small, marginal, and poor areas account for the largest area in Sichuan. They are led by the development of hydropower resources in old, small, marginal, and poor areas, leading to and promoting economic development in the region. A successful road that has been explored through practice over the past few years is a key issue that is of global importance in Sichuan’s economic development strategy. There are 1,419 large and small rivers in Sichuan, the vast majority of which originate from the northwestern plateau of Sichuan and the basin-county mountainous area, and flows southeast with a huge gap and into the Yangtze River.
