Huyện Đồng Văn (tỉnh Hà Giang), thuộc Công viên Địa chất Toàn cầu Cao nguyên đá Đồng Văn, là nơi có nhiều vị trí thể hiện tiềm năng phát triển du lịch đặc biệt là du lịch địa chất. Với mục tiêu thúc đẩy phát triển du lịch trên cơ sở khai thác các giá trị di sản địa chất và xây dựng chiến lược gìn giữ bảo tồn các điểm di sản địa chất, bài nghiên cứu được thực hiện cho 6 điểm di sản địa chất có tiềm năng ở huyện Đồng Văn, gồm hang Rồng, hang Hàm Rồng, hoang mạc đá Sảng Tủng, núi Đồn Cao, hang Nhù Sang, hang Ma Lé. | VNU Journal of Science: Earth and Environmental Sciences, Vol. 35, No. 1 (2019) 39-52 Original article Assessment of Geoheritage of Geosites in Dong Van District, Ha Giang Province Nguyen Thi Nhu Huong1, Nguyễn Thuy Duong2, Nguyen Van Huong2, Ta Hoa Phuong2,* 1 Faculty of Geography, VNU University of Science, 334 Nguyen Trai, Hanoi, Vietnam 2 Faculty of Geology, VNU University of Science, 334 Nguyen Trai, Hanoi, Vietnam Received 18 September 2018 Revised 19 March 2019; Accepted 20 March 2019 Abstract: Dong Van district in Ha Giang province, one of four districts of Dong Van Karst Plateau Geopark, has a number of geosites with great potential for geo-tourism development. By the aim to promote tourism development and to propose management plan, the present work selects six typical geosites in Dong Van district for assessment geoheritage values. The studied geosites are characterized based on the global framework of geological world heritage [13] and are evaluated values of science, potential education and tourism depending on a series of quantitative criteria from Rocha et al. [24], Brilha [5] with score ranging from 1 to 5 [25]. Furthermore, the qualification of the six-geosite group is recognized according to both the relevance of the meaning attributed to the objects by scientific communities (defined as relevance grade) and the public understanding of such meanings related to the social use of the objects (defined as abstract perceptiveness) from Reis and Henriques [22]. The results show that six geosites are classified into three types of geological sites including paleontology, geomorphology (covered by karst deserts and caves) and petrology-mineralogy. The quantitative assessment concerning to scientific requirement and educational as well tourism uses represents and defines the potential geo-tourism development on both the science communities and public understanding. The ultimate goal of the study is to use these results for the conservation of the .
