豫北平原咸水水文地质特征及开发利用

豫北平原是河南省重要的能源、冶金和纺织等工业基地,也是粮棉油料作物的主要产区。同时,又是水资源较匮乏的地区。但大量咸水(矿化度>1 0g L)资源得不到开发利用,且广泛分布的咸水已日益突出地成为环境水文地质问题。根据大量实地调查资料和地质成果,文章较详细地论述了豫北平原咸水含水层分布、富水性、补给、径流和排泄、水化学和同位素、利用现状及动态等水文地质特征。为缓解豫北平原水资源供需矛盾的压力,变害为利,根据咸水的分布状况、咸水农业利用和咸水养殖利用的适宜性、咸水改造方法和补源条件等,提出咸水开发利用与改良规划应"以用为主,以用促改"。结合各地实际情况,对不同矿化度的咸水应采取不同的开发利用方式、改良方案和措施。

The salt water hydrogeological characteristics and its exploration and utilization in the plain of North Henan

The plain of North Henan,which is the main industrial base of energy,metallurgy,spinning and weaving,is an important production area of grain,cotton and oil-bearing corps,etc.as well as a water-deficient area.But a great deal of salt water resources(TDS>1.0g/L) is not developed and utilized,which is becoming an environmental hydrogeological problem now.According to the date of field investigation and the geological achivements,the salt water hydrogeological characteristics in the plain of North Henan are discussed in the paper,for example,the distribution of water-bearing stratum,water abundance, supply,runoff,discharge,water chemistry,isotope,utilization state and movements etc.To reduce the water supply-need contradiction and to turn harm into advantage, based on the distribution state of salt water,the suitability of agricultural utilization and breeding utilization on salt water,the reformed methods of salt water and the conditions of supply sources,and so on,the plans of the exploration, utilization and reformation on salt water are put forward,and it is being the main and gearing up reformation to the utilization of salt water,combining actual cases in all areas,and taking the different ways of exploration and utilization,planing of reformation and measures on different TDS of salt water.
