| Abstract: | The area of soil and water loss in Dingxi Municipality is 6 726.6 km~2, accounting for 83.2% of the total land.In the region of soil and water loss,two hundreds and thirty-seven lager and medium sediment-trapping dams with the total capacity of 71.9612 million cubic meters had been established by the end of 2003.These dams play significant roles in trapping sediment,controlling floods,reducing hazards and facilitating the conversion of slope farmland to forest or grass land,improving the transportation and supplying drinking water for local residents and livestock as well. |
