This paper mainly discusses the law of abundant groundwater catchment and studies thedetermination of the locality of water abundance in the Quartzite and Slate region of SounthernLiaoning Province.The Localities of groundwater abundance in this region is unevenly distributed. Groun-dwater is stored in water-collectiong structure, aggregated in catchment network and abundantlvcollected in water-filled veins. Water-filled wins mainly form a pattern of double cross trel-dis-work. The best abundance positions of water are found at the joints of several water-filledveins.From the viewpoint of hydrography, wlth reference to many years’ achievement of surveyby means of composite profiling, electrode 5, audio-frequency and electrical sounding in theQuartzite and Slate region the groundwater abundance curve of water-filled veins can be clas-sified into many types. By making analyses of the characteristics of every such type, and byindicating the marks of the water aggregation localoty, We can effectively prove the deman-ded outcome.
