摘　　要：2013年秋季以来,每逢连续性降雨,浙江兰溪市六洞山省级风景名胜区地下长河的泥沙剧增,河水呈褐黄色,给景区旅游业经营造成了严重威胁。地下长河是石灰岩溶洞地下暗河,河水补给源地复杂。对地下长河景区的地形地貌、地层与地质构造、地表水与地下水运动进行分析。在实地考察的基础上,确定地下长河的河水泥沙来自其以东1 650 m的白坑村采石场区域。采石场的扩张不仅危及地下长河生存,而且使地下长河景区周边环境恶劣。依法协调景区发展与采石场之间的关系,采取工程措施与生态措施修复景区范围内的采石场环境,是地下长河泥沙治理的基本对策。From the fall of 2013,whenever there is continuous rainfall,Lanxi Liudongshan provincial-level scenic spot in Zhejiang would experience tremendous increase of silt in underground river,when its river water became brownish yellow,causing serious threat to tourism management. The underground river is a limestone cave underground river with complex water supply sources. By analyzing the landform,stratum and geological structure,surface water and groundwater movement of underground river scenic area and on the basis of site visits,it was confirmed that the underground river sediment comes from Baikeng village quarry area,which is 1 650 meters to the east of the scenic area. The quarry expansion not only endangers the survival of underground river,but also worsens the surrounding environment. The basic countermeasure for underground river sediment governance is to coordinate the relationship between scenic spot development and the quarry,and to restore the quarry environment in scenic region by adopting engineering and ecological measures.
