Abstract

Abstract Water, the vital element of the environment, considered for long time an inexhaustible and renewable resource, can have a limiting or favourable potential in the socioeconomic development of a region. Given that Romania's NE (Eastern Carpathians and the northwestern part of the Moldova Plateau) is undergoing increased competition for water resources, triggered by the intensification of agriculture and industrial development, better knowledge of the hydrological processes and the quality of surface water is required. The main purpose of the present study was to identify the hydrological processes determining the quality of surface waters based on analyses of the stable isotopic composition of water from precipitation, rivers and lakes and its quality parameters. For this, water samples were collected from 29 river sections, two lakes and a precipitation monitoring point over a period of 12 months (January to December 2019). The results show that the changes in the isotopic composition of precipitation and surface water are mainly controlled by air temperature, which, in turn, is influenced by the large-scale atmospheric circulation and other factors (e.g. precipitation amount, season, altitude). At the same time, the chemical analyses indicate that the water resources of the study area are predominantly characterized by a good chemical and ecological state, except for two sampling points with a moderate state and three with a poor ecological state.
东喀尔巴阡山脉降水和河水的稳定同位素和地球化学特征及其与大尺度驱动因素的联系
水是环境的重要组成部分,长期以来被认为是一种取之不尽、用之不竭的可再生资源,在一个地区的社会经济发展中可能具有限制或有利的潜力。鉴于罗马尼亚东北部(喀尔巴阡山脉东部和摩尔多瓦高原西北部)因农业和工业发展的集约化而引发的水资源竞争日益激烈,需要更好地了解水文过程和地表水的质量。本研究的主要目的是在分析降水、河流和湖泊水的稳定同位素组成及其质量参数的基础上,确定决定地表水质量的水文过程。为此,在12个月(2019年1月至12月)的时间里,从29条河段、两个湖泊和一个降水监测点采集了水样。结果表明,降水和地表水同位素组成的变化主要受气温控制,而气温又受大尺度大气环流及降水量、季节、海拔等因素的影响。同时,化学分析表明,除了2个采样点处于中等状态和3个采样点处于较差的生态状态外,研究区水资源以良好的化学和生态状态为主。
