Abstract: Generally speaking, peat bog doesn't develop in karst topography of subtropical zone, but there are duration and section which are favourable to the development of peat bog because of climatic fluctuation and the migration of climatic zone. Characteristics of peat bog originated and developed in karst area are mainly discussed in the paper, which are mainly decided by the developing stage of karst topography. During the humid climatic period, good drainage of surface water and ground water and strong erosion and corrosion are not favourable to the development of peat bog. During drier climatic period, strong accumulation leading to the obstruction of karst cave and fracture and thus resulting in logging water on the ground is favourable to the development of peat bog, e.g. the clay peat in the lower strata of the area was formed in the late dry cold Wurm-glaciation after Wurm sub-interglacial period, the silt peat-rotted wood in the upper strata was formed in the subbo-real period of lower temperature and humidity after Hypsithermal in Holocene, i.e.the period of peat formation in karst area is later than that in other areas.
