摘　　要：莒县白垩系地层岩石结构致密,孔隙裂隙不发育,地下水资源缺乏,进行富水性研究,圈定富水块段,对于当地水源供给保障具有重要意义。本文以西莲池寺-天井汪地区为例,依据"1:5万东莞幅、招贤幅区域水文地质调查"的实际调查分析数据,系统地进行白垩系富水性研究,从地形地貌、地层岩性以及地质构造三个角度探析地下水富集规律,为在白垩系缺水地区找水总结成功经验。最后归纳为四个主要因素,认为具备合适的地形地貌、适宜的地层岩性、良好的径流条件以及有利的蓄水构造,就有较大可能形成富水块段,这对于今后在其它地区开展找水工程及相关研究具有一定的借鉴意义。The rock structure is compact in cretaceous area of Juxian County, the pores and fractures are not developed, lack of groundwater resources, study on water abundance, delineation of water rich block, it is great significance for local water supply guarantee. This paper takes the Xilianchisi-tianjingwang area as an example, according to the actual survey and analysis data of 1:50 000 hydrogeological survey in Dongguan and Zhaoxian regional, systematically study cretaceous watery, analyze the law of groundwater enrichment from three aspects of topographic features, stratum lithology and geological structure, summarize successful experience for water exploration in cretaceous water shortage area. Finally summed up as four major factors, with appropriate topography, suitable stratum lithology, good runoff conditions and favorable water storage structure, water-rich block can be probably formed, it has a fairly referential significance for the future water exploration and related research in other areas.
