Abstract United profile method and high-density electrical method were used for the groundwater geophysical exploration in Huangliu, Jiusuo and Yacheng surveyed areas near the Jiusuo-Lingshui faulted zone in Hainan Island. The authors found that water yield of the drill hole at the low-resistivity anomaly place of the Jiusuo surveyed area is low, whereas water yield of the drill hole at the lumpy high-resistivity anomaly place of the Huangliu surveyed is relatively large. In the Yacheng surveyed area, drilling at the high-resistivity place found bedrock fissure-type hot springs. It is preliminarily held that the low-resistivity place in the above surveyed area has low water yield due to rock fracturing, serious argillation and poor water quantity, whereas the water yield of the drill hole at the lumpy high-resistivity place is relatively high due to the facts that bedrock fissures are not filled with soil and mud and the hydraulic conductivity is fairly good.
