Planning Strategies for Underground Space Use in Recreational Business Districts: A Case of South Parcel of Shanghai International Resort

Recreational business districts (RBDs) are often designated as the new growing point of metropolises upon sustainable development. Being a key component of a resort area and also a regional public service center, an RBD can face problems in spatial capacity and functional arrangement. In this context, it is essential that the use of underground space be involved and planned presciently. Through the case study of the South Parcel of Shanghai International Resort, which is also expected to serve as a city sub-center, this paper discusses key issues that drive the underground space use in RBDs and raises and expounds three main planning strategies for underground space. The findings of this study can provide insight into underground space planning in similar areas.
