RESEARCH ON THE KARST ECOLOGICAL ENVIRONMENT OF VERTICAL ZONED REGION: A case study of Jinfo Mountain National Nature Reserve in Chongqing

Due to the special geographical situation, the characteristics for karst ecological environment of vertical zoned region in Jinfo Mountain are very distinct. Based on the geological background of different altitude, the mountain shows vertically zoned characters, such as the distribution of soil, the diversity of biology, and the difference of karst dynamic systems. From the foot to the top of Jinfo Mountain, the soils appear as yellow soil, dark yellow soil, yellow brown soil and brown soil. There exist abundant type of animal and vegetation, which are rarely seen in similar kind of areas and enlarge the gene bank of wild biology. Owing to the difference of CO₂ concentration and hydro-chemical characteristics at different altitudes, the karst processes in the foot part is stronger than those in the top of the Jinfo Mountain.
