| 英文摘要 |
| The Radial Submarine Sand Ridges (RSSR) on the inner shelf of the Southwestern Yellow Sea is one of the largest of such system in the world. It was developed into great amount of land which is mainly used for agriculture. However, the coastal zone is facing many serious environmental and resources problems such as coastal erosion, ecological fragility and over- and abuse of coastal resources. Based on comprehensive field survey, this paper proposes optimization allocation and design of agri-landscape spatial structures targeting an integrated improvement in agricultural ecology, economy and amenity of the region as well as implementation of sustainable development strategy. As a case study, rectification approaches and conceptual optimization design for Rudong County are proposed and discussed. |
