Characteristics and value of geological relics in the Bijie Jiming Sansheng•Guizhou geopark

This paper explores the characteristics and value of geological relics in the Bijie Jiming Sansheng ? Guizhou geopark. Based on field investigations, we study the types and development characteristics of the geological relics in the park, and make qualitative and quantitative evaluation to its landscape. Our research suggests that， (1) The Bijie Jiming Sansheng ? Guizhou geopark is a typical representative of karst in the slope of the transition from the Yunnan-Guizhou plateau to the Sichuan basin； (2) From the watershed to the Chishui River valley, the karst landform changes are expressed by peak cluster depressions e karst doom depressions kkarst canyons with significant zoning, showing the development of karst landforms in the hydrological unit system； (3) The resource landscape types are complementary and have high values for research, ornamental and tourism development；(4) The types of geological relics in the park are divided into six big categories, ten small categories and ten sub-categories, dominated by karst gorges, caves, natural bridges, Tiankeng, peak clusters, karst dooms, stone forests and pictographic mountains, with waterscapes, geological sections, paleontology, environmental geological relics and geological structure relics as complements. Our work determines 3 national-level geogoical relics and 11 provincial-level geological relics in the park, which provides a basis for rational development and protection of geological relics in the park and advancing local tourism industry.
