Karst Formation Mode Research of National Geological Park Based on RS

Problems often encountered in karst at Mountain city construction and other infrastructure construction. to find out the genesis model of karst is important to prevent accidents. But in many areas, there is few research about karst development pattern, such as dabashan mountain area described in this article.Through our study on the genetic model about karst geological park in the region, we provides a train of thought for karst problem of urban construction in this area in the future. This National Geological Park is located in Daba Mountain.This park is different with other karst areas about karst landform development formation.The reason may be that Daba mountain is in the transitional belt line of north karst landform and south karst landform of China. The terrain mountain high deep valley, on the ground reconnaissance was carried out on the karst landform is hard to have overall grasp on karst, so we tried to use remote sensing images of karst scenic spot as auxiliary analysis, and has obtained the good effect. Remote sensing image interpretation can not only improve the efficiency of the understanding of karst development situation, at the same time due to a greater range of observation and analysis of karst scenic spot, the depth of understanding of the karst development through the analysis of the remote sensing images will also be greatly improved. Based on the remote sensing image formation patterns of karst scenic spot was analyzed.We think that Ba Taishan steep cliff is a residual funnel development under the planation surface. And Ba Taishan steep cliff is tangency to the long axis wall of the residual funnel, so the steep terrain appears more spectacular.
