摘要
在中国华北,地下岩溶多为溶隙网络状,主要发育强径流带系统。论文首先分析了中国南、北方岩溶差异的原因,包括地质差异、气候差异和时间因素限制,之后分别论述了岩溶水强径流带基本特征、岩溶水强径流带的宏观发育机制、强径流带的成因类型、地下岩溶发育深度、新构造运动与强径流带岩溶变迁,指出强径流带是地下岩溶选择性发育的结果。强径流带的成因类型和构成为:接触带型(约占47%);断裂带型(12%);岩溶河谷型(22%);河流渗漏集中补给型(9%);浅拗向斜型(6%);复合型(3%)。
In north China, the underground karst is more dissolved in the network, and the main development system is strong runoff belt. Firstly, the causes of karst differences in southern and northern China are analyzed, including geological differences, climatic differences and time constraints. Then the basic characteristics of the strong runoff zone of karst water, the macroscopic development mechanism of the strong runoff zone of karst water, the Genesis type of the strong runoff belt, the depth of the underground karst development, the new tectonic movement and the karst vicissitude of the strong runoff belt are discussed respectively, it is pointed out that the strong runoff is the result of selective development of underground karst, and the origin type and composition of the strong runoff belt are： contact belt type （approx. 47%）; fault zone type （12%）, Karst Valley Type （22%）, river leakage concentrated recharge type （9%）; shallow bend oblique type （6%）; complex type （3%）.
