辽宁连续两年遭受洪灾袭击,特别是1995年的灾害使农业遭到重大损失,深刻暴露了我省农业基础的薄弱之处。进入“九五”时期,要向农业强省迈进,必须进一步强化基础建设,提高防灾抗灾能力。为此,对特大洪涝灾害作一些反思,我以为很有必要。 水文资料表明,1995年洪水之大、洪峰来势之猛是百年来仅见的。但是,百年未遇的洪水并不等于百年未遇的降水。按主要成灾时间的7月28日～7月30日,其降雨量在100—300毫米之间,这样的降水规模不能说是百年未遇。那么,为什么不是百年不遇的暴雨都能形成百年未遇的洪水,进而造成特大洪涝灾害呢?我认为原因有这样几点:
Liaoning suffered floods for two consecutive years. In particular, the disaster in 1995 caused heavy losses to agriculture and profoundly exposed the weaknesses of the agricultural foundation of our province. In the “Ninth Five-Year” period, to advance to a strong agricultural province, we must further strengthen infrastructure and improve disaster prevention and resilience. Therefore, I think it is necessary to make some reflections on extra-large floods. Hydrological data show that the great flood in 1995, the fierce imposing peak is only seen for 100 years. However, the unprecedented floods in a century are not equal to those unprecedented in a hundred years. According to the main disaster time of July 28 ~ July 30, the rainfall between 100-300 mm, the scale of such precipitation can not be said that a century has not happened. Why, then, is it not a once-in-a-century rainstorm that can form the floods that have not happened in a hundred years and then cause catastrophic floods? I think the reasons are:
