汾河流域岩溶大泉的亘古亘今

The ancient and present of karst springs in Fenhe river basin

汾河流域内发育有8个规模不同的岩溶大泉,泉水的流量动态稳定,且水质良好,是当地重要的生活供水水源和农业灌溉水源,同时,许多著名的名胜古迹也依泉水而建。但随着经济的发展,各泉域内大规模的开发岩溶地下水,导致泉水流量不同程度的衰减,部分大泉甚至已经断流,这对当地的经济发展、居民生活都造成了一定程度的影响和制约。在国家大力倡导生态文明建设的推动下,汾河流域的生态修复规划已经实施,流域内岩溶大泉的生态环境已经好转,已断流岩溶大泉的复流将指日可待。

There are eight large karst springs of different scales in Fenhe river basin.The discharge of spring water is stable and the water quality is good.It is an important source of domestic water supply and agricultural irrigation in Fenhe river basin.At the same time,many famous scenic spots and historic sites are built on spring water.However,with the development of economy,the large-scale development of karst groundwater in various spring areas has led to different degrees of attenuation of spring water flow,and some large springs have even been cut off,which has caused a certain degree of impact and constraints on local economic development and residents lives.Promoted by the national vigorously advocating the construction of ecological civilization,the ecological restoration plan of Fenhe river basin has been implemented,the ecological environment of karst springs in the basin has improved,and the re-flow of karst springs which have been cut off will be in the near future.
