This paper took the main deposition interruption of the sixth, third and first order from D3 stalagmite and the second order from D4 stalagmite in the Dongge cave as the examples to show that interruptions occurred in 89964 a, 119658 a, 128650 a and 113399 a and ended in 316 a, 11960 a, 128211 a and 65500 a respectively according to the forming order. The age of the duration of 89684 a, 58 a, 439 a and 47899 a respectively indicated that the deposition interruptions and sedimentary cycles from the stalagmites have the property of the multiple orders and climate events,and also that the time of the deposition interruption is very long, and the property of climate events is complex. If there is interrupted sedimentation, it certainly adds more complicated connotation of climate, environment and geology, for instance, the second deposition interruption from D4 stalagmite is an integrated indication of climate, environment and geological events. The three collision events from Q2 stalagmite occurred in 74253 a, 60738 a, and 36800~40000 a respectively and the interval time is 13515 a and 22639 a. These data and sedimentary characteristics of the interruption interface from the upper part and lower part of stalagmite represented the calamitous property of the collision interface and contained information of paleoclimate environment. Dating of serial events must be carried out on the upper part and lower part of sedimentary interruption and collision interface together with observation of synthetic sedimentary characteristics of stalagmite parts on the basis of systematic dating, to enhance the dating and qualitative reliability and information of paleoclimatic environment.
