鲁中南岩溶塌陷区岩溶水污染途径研究

在鲁中南岩溶发育区,由于过量开采岩溶地下水,岩溶塌陷频繁发生,岩溶地下水也受到不同程度的污染。在岩溶塌陷区,岩溶地下水污染与岩溶塌陷有着密切联系。岩溶塌陷的条件、规模、频度、塌陷的时空阶段性等都直接影响岩溶地下水的污染程度。根据岩溶水的补给途径,岩溶水污染途径主要有四种:面状垂直渗透污染、带状侧向渗漏污染、点状塌陷坑灌入污染和超采岩溶水激发越流污染,不同的污染途径其污染源也不相同。要防止岩溶水污染,必须从根本上解决岩溶塌陷问题,切断污染途径,加强岩溶塌陷的防治和监测,从而保证岩溶水资源可持续发展。

STUDY ON POLLUTION ROUTES OF KARST GROUNDWATER IN KARST COLLAPSE REGIONS OF SHANDONG PROVINCE

In karst zones of the eastern collapse occurs year after year, and southern parts of Shandong Province, because of over-pumping karst groundwater, karst the karst groundwater also has been polluted. In the karst collapse district, there is relationship between pollution of karst groundwater and karst collapse. And the pollution degree of groundwater is affected by the conditions, scale, frequency and development stages of karst collapse. According to the supply route of karst water, there are four kinds of pollution-routes, i. e. , vertical infiltration pollution on plane, side seepage pollution on banding, influx pollution through collapse pit and leakage pollution caused by exploitation. And the pollution source is also different. In order to control karst water pollution, karst collapse must be controlled. And by severing the pollution-route and strengthening controlling and monitoring, the karst water should be sustainably developed.
