| 摘 要： | 在小流域水利工程设计计算中,普遍存在的问题是小流域上缺乏实测泥沙资料的情况.现介绍一种无资料地区水利工程设计泥沙侵蚀量计算方法,在移用泥沙资料时,首先对设计流域和参证流域的土壤性质、地形和植被等土壤侵蚀因子进行对比,对土壤侵蚀模数影响较大的因子进行修正.使移用的泥沙资料更符合设计流域的实际情况,可提高小流域设计中泥沙计算的精度,保证水利工程设计的质量. |
| 关 键 词： | 水利工程设计 资料移用 土壤侵蚀模数 影响因素系数 |

| Abstract: | In design and calculation of hydro-project JP2]for small watershed,the actual data shortage of sediment drift survey is often a key problem.The article introduces a new method of deciding soil erosion value for local hydro-project design JP]in the area without actual data.In applying other sediment data from other watersheds,the erosion factors such as soil characteristic,topography and vegetation is compared with each other,and the main factors that obviously affect soil erosion modulus should be modifie... |
| Keywords: | hydro-project design data reference soil erosion modulus coefficient of affected factor |
