This paper is based on the UNESCO materials which divided the earth science values of World Heritage to 13 themes (tectonic and structural features, volcanoes/volcanic systems, mountain systems, stratigraphic sites, fossil sites, fluvial，lacustrine and deltaic systems, caves and karst systems, coastal systems, reefs, atolls and oceanic islands, glaciers and ice caps, ice ages, arid and semiarid desert systems, and meteorite impact) and the submission texts which are provided by the State Parties to the World Heritage Committee. With sorting the 27 mountain properties on the World Heritage List to 5 kinds (biodiversity, geomorphic or physiographic features, landform diversity, culture and nature feature, and nature beauty), this paper evaluated the mountains on the natural and mixed World Heritages tentative list of China, and suggested that, with the current status, we should fill up some gaps, pay attention to the mountains on country boundaries, and carefully choose between applying unattached heritage and expanding an inscribed heritage with extent part.
