摘要
在分析国内外雨水利用历史、现状的基础上,对太行山片麻岩坡地的水文地质结构及特性进行了分析。结果发现,坡地的表层被一层双重、非均匀的复杂介质所覆盖,具体表现为“上覆土壤、下伏岩石”的“岩土二元结构体”;岩土二元结构坡地的空间变异性,特别是岩-土之间存在凹凸不平交界面的水文地质特性,为坡地侧向渗流的集蓄创造了条件,该技术创新了雨水集蓄的形式,在中国北方石质山地具有广泛的推广与应用价值。
To increase rainwater-harvesting efficiency and scientifically value the potential of regional rainwater becoming resource, based on analyzing the history and present situation of rainwater use in and out of china, analysized the hydrology and geology of slope in gneiss area. The surface of slope was covered by a complex medium, hereinto, the up layer was soil and the down layer was rock, we called the distribution rock-soil dualistic structure. The structure was suit for collecting rainwater and the collecting technique was innovative, which were easily spreaded and used in the mountainous area of north china.
