| A Study of Quality and Pollution Factors of Karst Groundwater in Lujiang River Basin in Southeast Yunnan |
| The Lujiang River basin is a typical area of karst fault basin in southeast Yunnan, and its main drainage system is connected with many fault basins and slope valleys. According to the latest investigation data of groundwater pollution, the quality of karst groundwater in the basin is mainly in Class III. The karst water points with super-class III water quality are more in the east and less in the west, and the proportion of underground river is the largest, the karst spring is the second and the manhole is the smallest. The major sources of pollution are industrial and mining enterprises and urban domestic waste, the factors affecting the pollution are the difference of environmental hydrogeological conditions, the type and intensity of pollution source, the degree of anti-pollution capability of karst aquifer and the difference of pollution mechanism of karst groundwater. The main pollution mechanisms of karst groundwater are water fall hole or karst cave pipe filling pollution mechanism, karst pore water-bearing medium seepage pollution mechanism and shallow overburden karst aquifer leakage pollution mechanism. Three countermeasures are put forward: the first is to adjust the industrial layout and reduce and eliminate the pollution sources; the second is to investigate the pollution sources and pollution ways and pay attention to the influence of environmental hydrogeological conditions on the migration and transformation of pollutants; the third is the development and protection of groundwater planning, the development of corresponding management measures, and the effective protection of water resources. |
