Establishing geoparks is an effective approach to protect natural resources and promote local tourism industry. The national geopark of the Hukou Waterfall is an important geopark which attracts more than 2 million tourists per year. The Hukou Waterfall is formed by combination of multiple knickpoints due to the longitudinal profile analysis. Like other waterfalls in the world, the Hukou Waterfall will disappear in the future. Considering the mechanisms of waterfall evolution, this paper suggests establishing control engineering, preserving the water and soil in nearby region, and reinforcing the structure of waterfall to preserve the landscape of waterfall.
