【Abstract】 The radial sandy ridges in Jiangsu coastal zone is largest radial sandy ridges which locates on the inter-tidal zone in the world. Its evolutionary history is different from other ridges and its hydrodynamic force is also distinctive. Otherwise the radial sandy ridges has unique geographic entity. It is an important region for the global climate change research and global sea-level change research. This paper expatiates on the radial sandy ridges nature features,then it sets forth the World Nature Heritage values that the radial sandy ridges reflects,which are (1) it records the global sea-level change history since Holocene; (2) it records the Yellow River change history which plays a decisive role on the China coast forming and controls the coast sharp; (3) it reflects the distinctive hydrodynamic of the west Pacific coast,now there is becoming a new sandy island that is incompatible with the global change conditions that the sea-level is rising and corroding is the dominated action; (4)it has the unique landforms which has no similar one in the world. So the radial sandy ridges is well qualified for the standard of the World Nature Heritage. Based on the development of the World Heritage,the paper discusses the importance that the radial sandy ridges applies the World Nature Heritage. This paper thinks the radial sandy ridges should apply for the World Nature Heritage as soon as possible.更多还原
