(四) 岩溶水流的补迳排方式既受控于不同序次的排泄基准面的大、小环境,同时又取决于不同等级(或级别)的单元自身的周边地层岩性的结构构造的组合关系及其水力状况,具有极强的系统性特色。众所周知,系统乃相对于环境而言,可以说环境决定系统(即主体),系统也决定环境。系统论学科的引进,带来了水文地质学科认识的深化。
The karstic system, in particular karstic sistem of carbonate rocks of North China Block is a complicated and organic system of groundwater flow in which there is an interrelation existing from the exposed surface area to the concealed and buried area. With the polycyclic character of geologic structure, the heterogeneity and the anisotropy of the medium structure, the transformation between continuity and discontinuity of water flow, the variable and complicted marginal condition which is difficult to be simplified, the random fluctuatin of water level due to the input frow surroundings, various social problems brought about by the exploitation of karstic water such as the reasonable utilization of resources, the promotion of what is beneficial and the prevention of what is harmful, and the environmental protection, as well as the numerous subsystems, the karstic water flow system of North China Block should be regarded as a complex megasystem. The main function of this megasystem is to form a deep-circulating active and organic groundwater flow system and thus to partially play the role of the Earth's hydrosphere. It thus follows that the research of this megasystem should be undertaken on the basis of traditional methods and methods suitable to the complex megasystem should be applied to the research in order to consider and solve problems macroscopically and to promote breakthrough of concrete study programs.
