中国北方岩溶水系统划分与系统特征

中国北方岩溶水以相对独立单元进行循环, 构成一系列规模不等的岩溶水系统。本文重点阐述两方面的内容: 第一从基本概念出发, 划分出119个岩溶水系统, 这些系统以高度开放, 环境质量脆弱, 发育规模大, 资源要素构成多、各要素间转化关系复杂, “水煤共存”为特点; 第二从岩溶水系统地质结构与岩溶水流场的叠置关系出发, 将119个系统归结为5种系统模式, 各种模式在分布与发育规模, 岩溶地下水循环、富集, 岩溶地下水流场形态和主要岩溶水文地质环境问题等方面具有鲜明的特征。

The Division and Characteristics of Karst Water Systems in Northern China

In northern China,karst groundwater cycles in relatively isolated units and has formed a series of water resource systems on different scales.This paper deals emphatically with problems of two aspects.First,starting with the basic concept,the authors divided the karst groundwater in northern China into 119 systems.These sys-tems are characterized by high openness,vulnerable environmental quality,large dimensions,numerous water re-source elements,complex conversion relations of the water resource elements an...
