摘  要:
据研究 ,黄河中游在暴雨 (2 4h)频率设计标准为 1%~ 0 5 %的条件下 ,坝地总面积达到坝控流域面积的 1/ 2 0~1/ 10时可达到坝系相对稳定。河龙区间在坝系达到相对稳定后 ,通过坝系拦蓄作用 ,每年可提供 16亿~ 2 9亿m3 的农业用水 ;有 42 4%的年份年径流大部分可被拦蓄利用 ;有 5 7 6%的年份坝系土壤水分补充量可达 5 2亿m3 以上

摘  要:
According to the research that under the conditions of the designed standard of rainstorm (24 hours) frequency in the middle reaches of the Yellow River as 1%~0.5%, when the total area of dammed land reaches to 1/20 ~ 1/10 of the total controlled area of the basin, a dam system can be relatively stable. After becoming relatively stable, the dam system located in the reach of He Long can provide 1.6 billion~2.9 billion m 3 of water for agricultural use. The most of annual runoff in 42.4% years can be stored and utilized and the replenished soil moisture can be more than 5.2 billion m 3 in 57.6% years.
