| Abstract: |
| Xiaomiaohong oyster reefs seen in Liyashan and Hongxidui, lie in coast near Dongzaogang Town of Haimen City, Jiangsu. It distributes in inner-tidal sand beach. Satellite images analysis determined its area of 3.5 km2. The reef-building oysters are mostly Ostrea rivalaris Gould and Crassostrea gigas, the living oyster reef is by Ostrea plicatula Gemlin. Many mollusks are cohabited among the reefs, such as Cantharus ceullei, Meretrix meretrix, Balamns albicostatus, Barbartia virescens and so on with obvious biodiversity a valuable for scientific reseach. However, environmental changes and disturbance by human development, this living-system has been shrunk and weakened. Only 25% of the area has leftover to the one in 40 years ago. In Liyashanit is even worse, only 1/16, and almost no living oyster exists in Hongxidui. Due to the uniqueness and specialty of the inter-tidal oyster reef, the authors strongly suggested an immediate establishment of Xiaomiaohong national natural reserve. In geomorphology, sedimentology, hydrology, biology and ecology, the authors evaluated the oyster reef in Xiaomiaohong tidal channel, putting forward many planned functions and practical measures which would be benefit Xiaomiaohong oyster reefs in sustainably development of the wetland. The planned reserve covers a total area of 3.5 km2, of which, 1.282 km2 is essential core area, 2.194 km2 as a buffer zone, and 0.276 km2 for experiment area. |
