Sustainable Development of Typhoon Prone Coastal Areas Based on SD Model

Sustainable development systems are a dynamic and complicated large systems, that can both be modestly destroyed and restrained by typhoon disasters. System dynamics can be used to study the problems of sustainable development. In this study, based on the theory of sustainable development and targeting typhoon disaster events in Leizhou Peninsula of China, we selected four subsystems (economy, population, environment, and water resource) using the background of typhoon disasters to empirically analyze the effectiveness and practicability of simulation models. Based on this, the restricting factors for sustainable development of the Leizhou Peninsula were assessed via scenario analysis. It was found that typhoon disasters introduced both benefits and harms to the economic development. The existing environmental protection investment did not meet the demands for social development, and the supply-demand contradiction of water resources remained severe. To promote sustainable development of the Leizhou Peninsula, the government has to adjust industrial structure, increase environmental investment, preserve water resources, and improve water quality.
