分析了渭河下游“05.10”洪水灾害减轻的原因,结论认为:①河道条件发生有利变化,减轻了防洪压力;②工程抗洪能力逐步提高,为减轻洪水灾害创造了有利条件;③防汛工作扎实细致,为夺取抗洪抢险胜利提供了有力保证。同时指出:①防洪工程抗洪能力依然较低,不可产生盲目乐观思想,加快防洪工程建设步伐仍是当务之急;②适度承担风险,由控制洪水向洪水管理转变,减轻渭河下游洪水灾害。
The reasons for the “05.10” flood disasters in the lower reaches of the Weihe River have been analyzed. The conclusions are as follows: (1) The favorable conditions of the river have changed and the flood control pressure has been relieved; (2) The flood control capacity of the project has been gradually raised, which has created favorable conditions for flood disaster mitigation; (3) In order to seize the flood and rescue victory provides a powerful guarantee. At the same time, it is pointed out that: (1) flood control ability of the flood control project is still low, no blind optimism can be generated, and it is imperative to quicken the pace of flood control construction; (2) moderate risk-taking should be changed from controlling flood to flood management and reducing flood disasters in the lower reaches of the Weihe River.
