【摘要】 本文运用系统论的观点，对瓮安丁家寨水源地岩溶地下水系统微观及宏观结构的组合形式及空间分布规律、地下水流场、动态与均衡进行了系统分析；对岩溶地下水系统进行了条件概化，建立了水文地质概念模型及数值模型；对岩溶地下水系统的转换功能特征进行了分析探讨，在系统分析的基础上．进行了子系统的划分，并对丁家寨－白水河子系统及草塘子系统的F4边界进行了分析讨论；提出子系统局部分水岭及F4不确定边界预报处理方法存在的某些问题，提出边界处理的改进意见，并试用二元线性回归预报方法对F4不确定边界进行动态预报。更多还原

【Abstract】 This paper analyses systematically macroscopic and microscopic associational pattern, spatial distributional regularity, water flow field, water dynamic regime and balance of karst groundwater system in Dingjiazhai water supply field,using a system theory. The hydrogeological conditions of the karst groundwater system are summed up, and hydrogeological conceptual and numerical models are established. In addition, the features of transformational function of karst groundwater system are analysed, based on which subsystems are subdivided. Also, the paper discusses the F4 boundary of Baishuihe and Caotang subsystems in Dingjiazhai water supply field and points out some problems about the forecast and treatment of the local watershed and indefinite boundaries of karst groundwater subsystems. An improved method for treating subsystem boundaries is suggested, which is to use binary linear regression analysis for forecasting dynamically the F4 indefinite boundaries更多还原
