永川地区位于川东盆地,是四川省今年特大洪灾中受灾严重地区之一,今年从七月到九月三日,八个县先后不同程度地发生五次暴雨和特大暴雨,范围之广,受灾之大,是历史上罕见的.受灾的原因,我们认为除了大气环流形成的暴雨为不可抗拒的因素外,与森林植被减少分不开.因为森林复被率低,滞洪作用就差.在这异常天气下灾害的机率也就增高.
The Yongchuan area is located in the Chuandong Basin. It is one of the worst-hit areas in Sichuan Province during this year’s extraordinary floods. From July to September 3 this year, eight counties have varying degrees of heavy rain and heavy rainfall five times in varying degrees. The reason for the disaster is that we think it is inseparable from the reduction of forest vegetation except because of the torrential rains caused by the general circulation of the atmosphere, because of the low rate of forest reclamation, and the poor flood retardation effect. In unusual weather, the probability of disasters will increase.
