从太原市“96·8·04”暴雨洪灾看城市水土保持工作的重要性

Attaching Great Importance to Urban Soil and Water Conservation: Reflection on the “96. 8. 04” Rainstorm Disaster in Taiyuan City

太原市北、西、东三面被重山环抱,汾河由北而南穿过其中,对市区构成暴雨洪灾威胁的面积约850km^2.虎峪河是城区西部山区最大的一条河流,流域面积47.1km^2.1996年8月4日,西部山区因连日降雨暴发了山洪,虎峪河奔腾咆哮的洪水,席卷了沿途桥粱,冲毁了河道堤岸,使繁华的迎泽西大街变成了狂泻洪水的河槽,造成的直接经济损失达2.86亿元.据分析,这次洪灾主要是不重视山区水土保持和人为乱堆滥弃废物造成的.水土保持应该走向更为广阔的主战场,不但要为山区农业建设服务,而且要为保证城镇安全服务.

through it from north to south, about 850 km^(2) of drainage area can cause rainstorm disaster to the district. Fuyu Rive is the largest one in the west mountainous area, with a catchment area of 47. 1 km^(2). On August 4, 1996, continuous rain happened in the west, causing flood in the Fuyu River. Severe flood caused damage to bridges, river banks and other facilities, and changed the busy West Yingze Avenue into a flood-running river channel. Direct economic loss reached 286 million yuan. This flood disaster was mainly resulted from sufficient soil conservation measures and irrational placing of various wastes. The field for soil conservation should be broader,it should not only serve the agricultural development in mountainous areas, but also contribute to the safety of cities and towns.
