胶州湾北岸不同水体水化学及氢氧同位素特征研究.

The study of the formation and migration of different water bodies is helpful to the rational development and utilization of water resources, and of great significance to the coordinated prevention and control of surface water and groundwater pollution and ecological environment protection. Taking the Jiaozhou Bay north shore shallow groundwater, river water and sea water as the research object, through the acquisition of water chemistry and hydrogen and oxygen stable isotope samples test and analysis, the statistics and Piper diagram were integrated used, different water bodies of water chemical characteristics and influencing factors were analyzed, and in combination with characteristics of hydrogen and the relationship between supply source and transformation was studied by oxygen stable isotopic. The results show that the fissure water of bedrock in the study area is mainly fresh water, and some points are affected by seawater intrusion, showing brackish water characteristics. Quaternary pore water is salt water and its chemical composition is stable. The chemical composition of the river water varies greatly, showing the characteristics of brackish water and salt water. There is a mutual transformation relationship between surface water bodies in the study area. The main source of water in Xiangmao River is atmospheric precipitation. Hongjiang River and Moshui River are mixed water of atmospheric precipitation and sea water, and Moshui River is more affected by sea water mixing than Hongjiang River. The seawater in Jiaozhou Bay is a mixture of river water and standard seawater. There is mutual transformation between groundwater and surface water in the study area. Besides atmospheric precipitation, there is a close hydraulic connection between bedrock fissure water and quaternary pore water, which is affected by seawater intrusion. Quaternary pore water is derived from the mixture of atmospheric precipitation and sea water, which is supplied by surface water or fissure water in bedrock during runoff and experiences evaporation in different degrees.
