崇明岛国家地质公园地质独特性及与世界典型地质公园的对比
The Unique Geological Heritage of the Chongming Island National Geopark (China) and Comparison with Other Parks in the Global Geoparks Network (GGN)
摘要
Abstract
The Chongming Island National Geopark contains 18 distinct geological landscapes set within a unique large estuarine environment that contains various geological, ecological, and human elements. This paper considers the geological evolution of the geopark within the Changjiang River delta area since the late Cenozoic, and places it in a global context. The unique geological heritage of the park is defined by four key elements: unconsolidated subsurface sediments several hundred meters thick; deltaic deposits; the dynamic estuarine geomorphology; and the tidal flat ecosystem. The thick unconsolidated sediments record the dual impacts of significant tectonic subsidence and sea level changes since the late Cenozoic. The deltaic depositional system reveals the development of the large river delta at 8 ka BP and the formation of Chongming Island, the largest estuarine al uvial sand island in the world. The estuarine geomorphology and ecosystem show the complex and dynamic nature of the geological and environmental system in a tide-dominated estuary. Compared with other geoparks within the Global Geoparks Network (GGN), the geological heritage of Chongming Island is obviously unique, covering the geological and geomorphological evolution of a large river delta and estuary. However, as many elements of the landscape are difficult to see, the park was constructed with the aim of determining how best to exhibit this geological heritage, and how to define the practical scope of geological heritage protection and geological tourism.关键词
