前些时候,我参加了有关小型水库死库容的确定、淤积和利用等问题的调查。在调查中,我觉得利用小型水库死库容的蓄水来灌溉农田,是一个值得重视的问题。据调查,山西省高平县已建成水库的死库容,一般都偏大。其原因是,在确定死库容时,从泥沙淤积对水库寿命的影响方面考虑得多,而如何充分利用库水来发展灌溉考虑得少。死库容大了,有效库容就相对减小,灌溉面积也随着减小。如许河、米山两座较大的小型水库,前者的死库容是120万
Earlier, I participated in the investigation of the determination, deposition and utilization of dead storage of small reservoirs. In the survey, I think it is a problem that needs attention to irrigate the farmland with the impoundment of small reservoirs. According to the survey, the dead storage capacity of the reservoir has been built in Gaoping County, Shanxi Province, generally larger. The reason for this is that much more is considered in determining the dead storage capacity in terms of the impact of sediment deposition on reservoir life, and less consideration is given to how to make full use of reservoir water to develop irrigation. Dead storage capacity, the effective storage capacity is relatively reduced, irrigated area also decreases. This river, Mishan two large small reservoirs, the former dead storage is 1.2 million
