地下水的埋藏深度、矿化度及水的化学类型与盐渍土的发生和演变有极其密切的关系,盐渍土的分区和地下水的水平分带同样也有相关性,因而不论国内和国外,对盐渍土的研究都很重视结合地下水状况的研究(这里所说的地下水主要是指最上层的潜水状况而言,下同)。所以在盐渍地区进行土壤调查时,在没有水文地质专业组配合的情况下,土壤工作者不仅应该而且必然要结合土壤观察点(包括剖面、钻孔等)进行地下水的研究(包括埋藏深度、矿化度、水化学类型等),而地下水的化学类型能反映地下水许多基本状况,通过它可以联系地下水径流的通畅程度、矿化度以及与土壤渍化的关系等。不言而喻,地下水化学类型图是盐渍地区土壤调查最基本的成果之一,它作为开发灌区及土壤改良的参考,也是研究当地盐渍土的基本资料。本文仅就如何编制地下水化学类型图问题略加叙述。
The burial depth, salinity and water chemistry of groundwater are closely related to the occurrence and evolution of saline soil. The division of saline soil and the horizontal zonation of groundwater are also relevant. Therefore, both domestic and foreign, Saline soil research places great emphasis on the study of the status of groundwater (groundwater here refers mainly to the diving situation at the top level, the same below). Therefore, when carrying out soil surveys in salinized areas, without the cooperation of hydrogeology specialists, soil workers should not only and inevitably conduct groundwater research (including depth of burial, depth of burial, Salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinity, salinization, and water chemistry). It goes without saying that the groundwater chemical type map is one of the most basic results of the soil survey in saline areas. It serves as a reference for the development of irrigation areas and soil improvement and is also the basic information for studying the saline soil in the area. This article only on how to prepare the type of groundwater chemical type profile a little narrative.
