沟壑坝库工程是水土流失地区小流域综合治理的最后一道防线,是晋西干旱黄土山区拦蓄径流泥沙,发展农业的一种主要形式。它主要是拦蓄坡面措施拦蓄不了的洪水、泥沙,起到缓洪、削峰、拦泥、淤地、固沟防冲的作用。对于实现沟壑川台化,防止水土流失,减少入黄泥沙和水库淤积,合理利用水土资源,变荒沟为高产稳产基本农田,发 Gully dam project is the last line of defense in comprehensive management of small watershed in soil erosion area, which is one of the main forms of blocking runoff sediment and developing agriculture in arid loess mountainous areas in western Shanxi. It is mainly to stop the impoundment of the slope can not hold the floods, sediment, play a slow flood, peak cutting, blocking mud, silt, gully and the role of anti-red. For the realization of gullies and rivers in Sichuan and Taiwan, to prevent soil erosion, reduce sediment into the Yellow River silt and reservoirs, rational use of water and soil resources, change the ditch to high and stable yield of basic farmland, hair
