山东省工厂化养殖鲆鲽类对地下水资源的影响调查研究

Investigation and Study on the Effect of Underground Water Resources Farmed Flounder in Shandong Province

摘要: 本文通过对山东省沿海地区的地下水资源分布和质量状况的调查，评估省区的地下水资源分布、类型和水质水量以及可开发利用的潜力。调查研究表明：沿海大部分地区地下水主要以基岩裂隙水(浅棕色区域)为主，径流模数小于50,000 m³/km²•年，多年平均地下水天然补给资源量为216.38亿m³，可开采资源量为178.65亿m³。其中，淡水、微咸水天然补给资源量为206.19亿m³。目前，开采现状为123.30亿m³。其中，工业开采27.09亿m³，农业开采77.84 m³，生活用水18.37亿m³。为实现地下水资源的可持续利用，建议采取如下措施：1) 加强地下水开采管理。2) 合理规划，适度开发。3) 采用污水集中收集处理措施和封闭式循环水系统。4) 加强地质普查与水质监测。5) 继续开展井盐水利用与海水入侵关系研究，确保地下水养鱼能迈向可持续发展。

Abstract: Based on the investigations of distribution and quality of the underground water resources in the coastal of Shandong Province, we assess provincial underground water resources distribution, type and water quality as well as the exploitable potential. The results showed that large part of coastal underground water was in bedrock fissure (light brown). The runoff modulus is less than 50,000 m3/km²/year. Average annual natural recharge of underground water resource is 21.638 billion m³, and the exploitable resources amount is 17.865 billion m³. The natural supply of fresh water, brackish water resource amount is 20.619 billion m³. At present, the extracting amount is 12.33 billion m³. Among them, the industrial exploitation is 2.709 billion m³, agricultural exploitation is 7.784 billion m3 and 1.837 billion m³ of water for daily life. In order to achieve sustainable use of underground water resources, we recommend the following measures: 1) To strengthen underground water management 2) To plan appropriate development of flounder fish culture. 3) To use closed circulating water system and sewage collection and treatment measures. 4) To strengthen geological survey and water quality monitoring. 5) To study on salt water and seawater intrusion, and ensure that fish can move towards sustainable development of groundwater.
