本文侧重讨论岩溶水循环中产流与汇流、岩溶区流域面积确定、地表水与地下水划分、以及解决这些问题的技术方法。

In this paper, the mechanism of runoff-producing and flow confluence in karst area, the structure function of karst hydrological conceptual model, and the problem of modelling process are discussed.

由于岩溶地下水分布难以量测，岩溶水文系统多为黑箱或灰箱，采用岩溶水文模型量化其水循环过程常存在许多疑难问题。

There are some problems in modelling karst water circulation using hydrological model as lack of information of groundwater distribution in karst system (black box or grey box).

强径流带内岩溶水积极参与现代水循环，平均滞留时间为51年，具有较强的更新能力。

Karst water in the strong runoff zone takes an active part in the modern water cycle, with an average residence time of 51 years, and so has a relatively strong renewable capacity.
