Fenhe Reservoir is responsible for Taiyuan water supply, flood control and Jinzhong basin irrigation water large reservoirs, Shanxi’s economic development has an important role. For more than 30 years since the reservoir was built, siltation sediment is 310 million m 3, accounting for 43% of the total storage capacity. In order to alleviate reservoir siltation and promote the people in the upper reaches of the region to get rid of poverty and get rich, the provincial government decided that from 1988 onwards, each year will invest 20 million yuan to basically complete the control of soil and water loss in the upper reaches of the reservoir in a decade. After five years of comprehensive management, it has completed 751km ~ 2 of comprehensive treatment measures, newly added 18,000 hectares of basic farmland, built 62 silt dam, newly built 119 flood-producing silt-making sites, and built and sealed Water conservation forest 52,600 hm ~ 2, control increased by 20.4%, reducing sediment storage 22.4%, and achieved significant ecological, economic and social benefits. On the basis of summing up the experience of governance, we put forward the strategies and tasks for the next five years.
