1981年7—9三个月,四川省连遭暴雨和特大洪水,给农业生产造成很大损失。被淹、被冲耕地达1,200多万亩、其中,冲毁农田220多万亩,有40多万亩被冲成乱石滩,光板板,近期内难以复耕。总结这次洪灾的经验教训,究其发生的原因,固然主要是由于大气环流的变化所造成,但从我们的工作上检查,也是值得深省的。在治理坡耕地上,速度慢,面积小,有的质量还不高,综合治理也不够,因而抗御自然灾害的能力弱,未能把这次洪灾的损失减小到最低的限度,这是一个沉痛的教训。
During 7-9 months in 1981, Sichuan Province suffered heavy rainfall and severe floods, causing heavy losses to agricultural production. Flooded and infested with more than 12 million mu of land. Of these, over 220 million mu of farmland have been washed away and more than 400,000 mu have been washed into rocky shoals and boards, making it difficult to re-farm in the near future. To sum up the lessons learned from this flood, the reasons for its occurrence are mainly due to the changes in the atmospheric circulation. However, it is also worth considering from our work to examine this. In the management of sloping farmland, the speed is slow, the area is small, and some are not high in quality, and comprehensive management is not enough. Therefore, the ability to resist natural disasters is weak and the loss of the flood can not be reduced to a minimum. This is a Painful lesson.
