Abstract:

Geological relics are precious and nonrenewable natural resources. The protective development of geological relics not only is the premise of its sustainable development and utilization but is also an indispensable part of ecological civilization construction, poverty alleviation, and rural revitalization. On the basis of the survey data of geological relics in the Gansu section of the Yellow River Basin, the spatial distribution characteristics of geological relics in this area are evaluated using the nearest neighbor index and the GIS spatial analysis method. Then, suggestions for the sustainable development and utilization of geological relics are introduced. The results show the following: (1) 1046 geological relic points are found in the geological relic survey of the Gansu section of the Yellow River Basin, 153 of which are of great value. The geological relics in the study area are widely distributed in space and have various types and unique connotations, mainly including clastic rock landforms, stratigraphic sections, and paleontological trace fossils. The characteristics of its uneven distribution are related to the local climate zoning, geomorphic zoning, water system distribution, geological structure development, and so on. (2) According to their occurrence environment and development characteristics, the geological relics in the study area are divided into two geological relic areas, six districts, and 15 communities. (3) Taking the integration and optimization of national nature reserves as an opportunity, promoting the sustainable development and utilization of the geological relics in the Gansu section of the Yellow River Basin is suggested. This may be done through multilevel and diversified development and utilization paths such as the construction of geoparks, research and study travel bases, characteristic towns, and geological and cultural villages.

Key words: geological relic types, spatial distribution characteristics, natural zoning, sustainable development and utilization, Gansu section of the Yellow River Basin
