Analysis on Runoff and Sediment Reduction Benefit by Erosion Control Measures in Jialu River Watershed |
| |
| Abstract: | Jialu River watershed, a first-class tributory of the Yellow River, is located at gullied and rolling loess region. Soil and water conservation work in the watershed began in early 1950's, after the Northern Agriculture Conference in 1970, a large scale comprehensive management was conducted. By the end of 1989, the aetual survival area by all kinds of erosion control measures in the watershed had reached 32023 ha. the harnessment degree was 28. 24%. According to calculation by hydrographic method and soil and water conservation method, 328 million m3 of runoff and 69. 4 million t of sediment in the watershed from 1970 to 1989 were reduced , the runoff and sediment redtiction efficiency were 20. 9% and 23. 7% seperately. |
