防汛抗旱减灾我国大江大河多次发生大洪水,台风登陆频繁。依靠不断完善的防洪体系,广大军民与洪水、台风灾害进行了顽强的斗争,取得了重大胜利,最大限度地减轻了灾害损失。1949年以来,全国防洪减灾直接经济效益达3.93万亿元,防洪减淹耕地24亿亩(1.6亿hm~2),年均减免粮食损失1029万t。1991年以来,平均每年抗旱浇地面积4.6亿亩(0.31亿hm~2),年均挽回粮食损失4059万t。

Relying on the continuous improvement of the flood control system, the majority of soldiers, civilians, floods and typhoon disasters have strenuously fought and won major victories and the disaster losses have been lightened to the maximum extent. Since 1949, the direct economic benefits of flood control and disaster mitigation in the country have reached 3.93 trillion yuan, and 2.4 billion mu (160 million hm 2) have been flooded and flooded, with an average annual reduction of 10.29 million tons of grain loss. Since 1991, the average annual drought-resistant irrigated area has reached 460 million mu (31 million hm 2), with an average annual loss of 40.59 million tons of grain.
