原板桥水库上游,水土流失非常严重。大坝建成后,既不治理水库上游的水土流失,对大坝工程经营管理也很差;坝体出现了险情,几次上报水利部门,官僚主义者不屑一顾。1975年8月一次洪水,主管人员惊慌失措,束手无策,大坝不幸溃决,制造了一场空前的人为灾难,数十万人丧生。灾难后十多年来,水库上游童山秃岭依旧,水土流失愈演愈烈,大坝又在原址上耗费巨资重修。历史是无情的。如果一如既往,重蹈覆辙,板桥水库必然再度溃决。四川的水库就有五建五溃的先例;云南1985年一次就垮了13座大坝;最近山西溃决一个大坝,冲击18个城镇,淹没300多个村庄。前几年公布的每年溃决90座大坝,目前这个数字可能突破了。不注意水土保持,水利工程定会变成水害工程。
The original Banqiao Reservoir upstream, soil erosion is very serious. After the completion of the dam, neither the soil and water loss in the upper reaches of the reservoir was controlled, but the operation and management of the dam was also very poor. Dangers appeared in the dam, which were reported to the water conservancy department several times and the bureaucrats dismissed it. In a flood in August 1975, supervisors were panicked and helpless, and the dam was unluckily beaten to create an unprecedented man-made disaster that killed hundreds of thousands. More than a decade after the disaster, the Bald Ridge in Tongling Mountain in the upper reaches of the reservoir remained the same. As the soil and water loss intensified, the dam costly rebuilt on the site. History is ruthless. If, as always, repeat the same mistakes, Itabashi reservoir inevitable collapse again. There are five precedents for the collapse of Sichuan’s reservoirs; Yunnan once collapsed 13 dams in 1985; recently, a dam was ruptured in Shanxi, affecting 18 towns and submerging more than 300 villages. The collapse of 90 dams, announced a few years ago in the past, is likely to break through this figure. Do not pay attention to soil and water conservation, water conservancy project will become a water damage project.
