| 8. | On this basis , it also studies the main recharge of groundwater , discusses the relationships between river and groundwater , shallow confined water and phreatic water , northern karst water and quaternary phreatic water as well , and get the recharge percentage which river recharges to phreatic water
在此基础上，研究了地下水的补给来源，探讨了河水与地下水、浅层承压水与潜水、北部岩溶水与山前第四纪潜水之间的相互关系，确定了河水对潜水的补给比例。 |
| 9. | Therefore , on the basis of brief summarization of geography , society and economy of yin - chuan basin , the hydrogeological condition was stated and analyzed , the groundwater resource was assessed using balancing method . results showed the quality of phreatic water in yin - chuan basin is bad and can be easily contaminated , it is not suitable for water supply of industry and living
因此本文在对银川盆地的自然地理和社会经济概况进行概述的基础上，分析、论述了盆地的水文地质条件，采用均衡法对盆地的地下水资源进行了评价，并计算了天然补给资源量、可开采资源量。 |
| 10. | The oil field exploiting impacts on water resources are analyzed in this paper , points out that the current situation of water pollution as follow : the surface water have greatly polluted , the quality of the phreatic water is going worsen , and the deep groundwater quality is not be good , and make out the main pollutants , then utilizes the artificial neural network analyses the collected water quality information data and predicts the water quality in the daqing area , makes a reasonable assessment , which will present theoretic basis for water resources protection and pollutant prevention in oil field
摘要首先分析了油田开采对大庆地区水资源的影响，指出水污染现状：地表水严重污染，潜水水质趋于恶化，深层地下水水质不佳，同时指出水污染的主要污染物，并运用人工神经网络度对长期收集的水质监测资料进行了分析和预测，对该区水资源水质做出了比较合乎实际的评价，为油田水资源的保护和污染防治工作提供了理论依据。 |
