摘要
在对多沙粗沙区不同类型区水土保持措施组合的调查、评价的基础上,分析了《黄河近期重点治理开发规划》中皇甫川、三川河和马莲河3条支流不同措施组合对径流的影响。结果表明,水土保持措施规划实施后,对径流的影响在枯水年分别为3278万m3和2159万m3,占河龙区间多年平均实测径流量的20.9%,若是丰水年或平水年将分别占到58.8%和38.9%。可见,水土保持措施对径流的影响作用是很大的。
On the basis of the investigation and appraisal on the different soil and water conservation measure combinations in sandy area, this paper analyzes the effect of different measure combinations on runoff in three rivers of Huangfuchuan, Sanchuanhe and Malianhe which are listed in the Key Harnessing and Development Planning in the Yellow River Basin in Near Future. The results indicated that after the implementation of the planning of soil and water conservation measures, the effect on the runoff in dry year is 32.78 million m^3 and 21.59 m^3, which occupies 20.9% of the annual average measured runoff in dry year, or 58.8% and 38.9% in wet year and in normal year. Therefore the effect of soil and water conservation measures on runoff is obvious.
