摘　　要：九天洞是一个典型的直接由外源水补给形成的流入型洞穴。洞内大片分布的石花起源于四大古水池沉积物的存在。九天洞发育于第四纪早更新世晚期至中更新世早期,经历过成洞期、残余水流(古水池)活动期(中更新世中、晚期)石花发育期(晚更新世以来)和主要滴石、流石(含浅水池)沉积期(晚更新世晚期至今)等发育阶段。今日的九天洞又是一个残余洞穴,已被完全蚀去的近流入口段的洞穴长度不小于200m,约占洞穴全长的37%。九天洞及其洞穴群的景观资源价值和科学价值,在我国北方喀斯特洞穴中占有重要的地位。As a typical inflow cave,Jiutiandong is formed by direct recharge of allogenic water. Widely distributed calcite and aragonite crystal in the cave passage are originated from ancient pool deposits. Jiutiandong cave was development between the late period of the early Pleistocene and the early period of the middle Pleistocene Epoch, and has experienced many development processes as follows： cave passage formed stage; remnant water flow activity （ancient pools）stage （during the middle and late period of the middle Pleistocene Epoch）; crystal flowers development stage （from the late Pleistocene Epoch） ; and main drip and flowing（including shallow pools）deposits stage（from the late period of the late Pleistocene Epoch until now）. Jiutiandong cave is a remnant cave with more than 200m （approximately 37% of total length）of the cave passage near the entrance had gone by erosion of the inflow water.
