| 摘 要： | 近50 a来官厅水库上游流域侵蚀产沙总量为4.57×109t,其中水土保持措施拦沙量7.71×108t,占总产沙量的16.89%;水利工程拦沙量7.65×108t,占总产沙量的16.76%;引洪淤灌减沙量9.65×108t,占总产沙量的21.14%;河道淤积沙量8.16x 108t.占总产沙量的17.88%;官厅水库淤积量7.50× 108t,占总产沙量的18.02%;官厅水库下泄4.25×108t,占总产沙量的9.31%.20世纪的后20 a,流域内的水土保持措施拦沙量大幅度提升,和1950-1980年间相比,水土保持措施拦沙率提高了26.27%. |

| Abstract: | Investigation of sediment transport balance in the Guanting Reservoir watershed indicated that in the past fifty years,the total sediment yield resulting from soil and water loss was 4.565 billion tons.Soil and water conservation measures kept about 0.771 billion tons,16.89% of the total sediment yield.Water conservancy projects retained about 0.765 billion tons,16.76% of the total sediment yield.Irrigated lands intercepted about 0.965 billion tons,21.14% of the total sediment yield.River beds and courses a... |
