1981年6月下旬至9月中旬,在我省沱、涪、嘉、岷四江流域,凉山、渡口、荣昌、马尔康、金川等138个县市,先后出现了6次大暴雨,有119个县受灾:其中7月12日～15日的特大暴雨,使沱、涪、嘉三江流域和重庆以下的长江干流出现了特大洪水,岷江、渠江、青衣江相继出现了较大洪水。为了认真总结1981年洪水的经验教训,研究水土保持措施中的蓄洪减灾作用,特以“81,7”洪水为例进行如下讨沦。
From late June to mid-September 1981, six heavy rainfalls occurred in 138 counties and cities including Tuo, Fu, Jia, Min Si River, Liangshan, Ferry, Rongchang, Malcolm, Jinchuan, etc. There were 119 counties Disaster: Among them, heavy rainfall from July 12 to July 15 caused extra-large floods in Tuo, Fu, Jia Sanjiang River basins and the main Yangtze River below Chongqing, and large floods successively occurred in Minjiang River, Qujiang River and Qingyi River. In order to conscientiously sum up the experiences and lessons learned from the floods in 1981 and study the role of flood control and disaster mitigation in soil and water conservation measures, take the “81,7” flood as an example to discuss the following issues.
