摘  要:
为了解喀斯特地区地层岩性对地表径流形态产生的影响,以花溪河流域为例,探讨研究提取出的实际河流、理论河流与花溪河流域岩性,从而对比得出喀斯特地区岩性对地表径流形态产生的影响。结果表明,实际的地表径流比提取的理论径流长度要短,造成这种数据差异的原因是喀斯特地区典型的岩溶作用与溶洞、地下河的共同作用使地表径流流失进入地下,且不同岩性下对地表径流形态产生的影响不同。

摘  要:
In order to know the impacts of stratum lithologies in Karst area on the surface runoff pattern,this paper takes Huaxi River basin as an example to explore and discuss the extracted actual river,theoretical river and lithologies of Huaxi River basin,thus to obtain the impacts of stratum lithologies in Karst area on the surface runoff pattern. The result shows that the actual surface runoff is shorter than the extracted theoretical runoff. The reason for this kind of data difference is that the typical karstification in Karst area as well as the combined action of Karst caves and subterranean rivers make surface runoff wash away into underground,and different lithologies exert different impacts on surface runoff patterns.
