由中国地质学会水文地质专业委员会主持召开的“东部沿海地区环境水文地质学术讨论会”于1987年5月在大连市召开。参加会议的有地矿部、冶金部、中国科学院等系统的代表共51人。沿海地区的环境水文地质条件与内陆有明显不同。这里地势低平,含水层厚度小,地下水交替较差,矿化度高。水资源较山前地带要少,尤其是受到现代海水影响的地区,往往在深部才可能有可用的淡水。这里的地下水体自净能力也较差,一旦遭受污染很难自净复原。我国东部沿海地区随着经济的发展,带来了环境水文地质问题,包括工农业生产的废水废渣,工业废气在大气中造成的酸雨;以及由于对地下水强烈开采引起海水入侵等等。
The “Symposium on Environmental Hydrogeology in the Eastern Coastal Region” was held in Dalian in May 1987 by the Committee of Hydrogeology of China Geological Society. A total of 51 delegates attended the conference, including the Department of Mines, Metallurgy and Chinese Academy of Sciences. Environmental hydrogeological conditions in the coastal areas are significantly different from those inland. Flat terrain here, low aquifer thickness, groundwater alternating poor, high salinity. Water resources are less than in the Piedmont, especially in areas affected by modern seawater, where freshwater is often available in deep water. The groundwater body here is also poor in self-purification ability, and once it is polluted it is difficult to recover from pollution. With the economic development in the eastern coastal areas of our country, environmental and hydrogeological problems have been brought about, including waste water from industrial and agricultural production, acid rain caused by industrial waste gas in the atmosphere, and seawater intrusion due to intense exploitation of groundwater.
