江西省东乡红色断陷盆地的水文地质特征及裂隙水资源

本文分析了江西省东乡县红色断陷盆地的水文地质特征,着重研究了红盆外缘含水系统中的地下水顺导水断裂向盆地径流对形成红壤裂隙的补给资源所起的作用,并概括出三种类型的剖面。指出每一种剖面应研究的重点,粗略估算了地下水资源。最后阐述了红层地区裂隙水的找水方向和调查方法。

THE HYDROGEOLOGICAL CHARACTER AND FRACTURE-WATER RESOURCE OF DONGXIANG RED GRABEN BASIN IN JIANGXI PROVINCE

The hydrogeological character of the Dongxiang red graben basin in Jiangxi province, the nature of the river system and landforms and their relationship with the geologic structure in the developing area of red soil are demonstrated in this paper. In view of that the red beds in this area are distinguished for their poor water storage and strong conductivity, so the emphasis of investigation should be put on the aquifer systems outside the red graben basin and the role in the replenishment of fracture-water in red soil region played the groundwater runoff percolating through the water-conductible faults from these aquifer systems. According to the various relationships of the red graben basin with the aquifer systems outside it, three kinds of hydrogeologic section are advanced in the paper for analysis. The key points for research had been indicated and the gfoundwater resources had been roughly estimated section by section. Finally, the direction of fracture water research and the method of fracture water investigation in area of red soil are expounded.
