同位素技术释解苏锡常地区浅层地下水水循环机制

本文利用同位素量值及常规指标含量在不同赋存介质下所表现出的规律，垂向上选取河水、潜水、微承压水进行分析，释解苏锡常地区浅层地下水水循环系统运移机制，为合理开发利用苏锡常地区浅层地下水提供理论依据。全区浅层水的补给资源量十分可观，但地域间存有差异，其中东部苏州地区补给量大于西部常州地区，沿江地带大于东部地区。

Circulation mechanism of shallow ground water in Suzhou-Wuxi-Changzhou area interpreted using isotope techniques

The occurrence of isotopes in different environments was firstly analyzed in this paper, then its intrinsic relationship to conventional chemical index was examined. Water samples were vertically collected from rivers and groundwater in the phreatic and semi-confined aquifers. The transportation mechanism of groundwater in the shallow groundwater system in the study area is explained in this paper based on the testing results. It can be used as the theoretical reference for reasonable exploitation of the shallow groundwater. Groundwater resources in the semi-confined aquifer are quite abundant, but regional differences exist.
