在豫西伏牛山脉,深山区中,汛期常常出现表层土的滑玬和岩堆的崩溃,群众称为“土、石子”。山坡滑坍给人民带来了严重的灾害,它不但可以摧毁渠道、水库、堰坝等各种工程建筑物,破坏农田和交通,并且往往造成严重的房屋倒坍及生命死亡,成为这类地区急待解决的重要问题之一。据西峡县1955年汛期15个乡的统计;叶现山波骨坍1380多处,冲毁耕地24829亩(其中多数乡冲去了总耕地面积的70%以上),例坍房屋1492间,冲走和砸死310人,被砸伤的129人,冲走牛128头,砸伤44头,冲跑羊55只,猪123只,粮食94556斤,农具9570件。1956年“土子”亦很严重,川县白沙洞乡大小发生1000余处。又如南召县薛老庄沟,流域面积仅2.5平方公里,汛期
In the western Henan Funiu Mountains, mountainous areas, the flood season are often surface slippery and collapse of rock piles, the masses known as the “soil, gravel.” The slump on the slopes has caused serious disasters to the people. It can not only destroy all kinds of engineering structures such as channels, reservoirs and weirs, destroy farmland and traffic, but also often lead to serious housing collapsing and life-threatening deaths. One of the important issues urgently to be solved. According to the statistics of 15 townships in flood season of Xixia County in 1955, there are 1380 leaf collapsing fields in Yexia, and 24,829 mu of cultivated land is washed away (most of which rushed to more than 70% of the total cultivated land) And smashed 310 people, injured 129 people, washed away 128 cattle, crushed 44, washed run 55 sheep, 123 pigs, grain 94556 pounds, 9,570 tools. 1956 “soil son” is also very serious, Chuanxian Baisha Dongxiang size of more than 1,000 place. Another example is the Nanzhao County Xue Laozhuang ditch, the basin area of only 2.5 square kilometers, flood season
