    浑河流域沈阳-抚顺段地下水年龄及循环特征

    AGE AND CIRCULATION CHARACTERISTICS OF THE GROUNDWATER IN SHENYANG-FUSHUN SECTION OF HUNHE RIVER BASIN

    • 摘要: 利用3H法对浑河流域沈阳-抚顺段浅层地下水年龄进行了计算. 通过对地下水年龄分区,进而分析其循环特征,为该地区地下水资源合理开发利用和城市资源环境承载力研究提供科学依据. 结果表明: 总体上,浑河流域沈阳-抚顺段地下水主要为近60 a以来补给的现代水,并且从东部山区至西部平原地区沿着地下水流向年龄逐渐增大. 年龄为小于30 a、30~60 a、大于60 a的地下水分布面积占研究区总面积的比例分别为34%、31%、35%. 流域上游为丘陵山区,含水层结构单一,颗粒较粗,地下水年龄小于30 a,地下水循环交替强烈. 流域中游含水层逐渐增厚,地下水循环交替强度逐渐减弱,地下水年龄增大为30~60 a. 流域下游含水层逐渐由单层转变为双层和多层,颗粒较细,地下水循环交替缓慢,地下水年龄也增大为大于60 a.

       

      Abstract: The age of shallow groundwater in Shenyang-Fushun section of Hunhe River Basin is calculated with 3H isotopic method. Through the age zoning of groundwater and analysis of its circulation characteristics, the paper provides a scientific basis for the rational development and utilization of groundwater resources and study on carrying capacity of urban resources and environment. The results show that the groundwater in the Shenyang-Fushun section is mainly the modern water replenished in the past 60 years, and the age of groundwater flow increases gradually from the eastern mountainous area to the western plain. The distribution area of groundwater aged less than 30 a, 30-60 a and more than 60 a account for 34%, 31% and 35% of the total of the study area, respectively. The upper reaches of the basin are hilly and mountainous area, with single aquifer structure, coarse particles, groundwater age less than 30 a and strong groundwater circulation. The aquifer in the middle reaches thickens gradually, the alternation of groundwater circulation weakens gradually, and the groundwater age increases to 30-60 a. The aquifer in the lower reaches gradually changes from single layer to double layer and multilayer, with fine particles and slow water circulation, and the groundwater age increases to more than 60 a.
