摘要
洛塔以屋檐洞地下河系为主,地下水资源丰富,地表水缺乏。采用修建溶洼水库、地下河出口和岩溶泉围堰、堵地下河引水的开采方法,在深埋大于200m的地下河内开凿引水隧道,引水灌溉并供人畜饮用,取得了良好的效益。通过对表层岩溶带地下水的开发,解决了分散居民长期困扰的生活用水问题。根据区内水资源分布特点,总结出高洼堵洞修建溶洼水库;斜坡谷地堵截引水;河间谷地建立梯级电站开发水能资源;发展林业,增加森林对地下水资源调蓄能力的水资源持续开发利用模式。
Wuyandong is the most important subterranean river system in Luota, where groundwater is abundant but surface water is short. Big benefit is gained for irrigation and for men and domestic animals by excavating tunnels to draw the underground river water, and by building reservoir in karst depression, by cofferdaming at the outlet of the subterranean river and the karst springs, and by building subterranean reservoirs as well. The problem of short of drinking water that puzzling the dispersively distributed local residents for a long time is resolved by exploiting groundwater in epikarst zone. According to the characteristics of the distribution of water resource, the multiply models of sustainable use and exploiting water resource are summarized as follows: blocking caves and building reservoir in higher depression, importing water by blocking and intercepting slop valley, exploiting water power by building stepped power stations in valleys, and improving the capacity of forest to regulate the dynamic state for groundwater by reforestation.
