ABSTRACT

Based on the waterlogging disaster caused by typhoon landing and affecting the human settlements in the coastal plain of northern Zhejiang in recent years, this study explores the disaster mechanism of typhoon waterlogging affecting the human settlements from the four dimensions of physical geography, social structure, economic development and built environment. Through regression analysis, it is clear that "the ineffectiveness of polder" is the most key factor, high-density depressions, high water retention of imperious surfaces, low GDP and imperfect rescue circle are also closely related to disasters, which reveals that the security of human settlements in coastal plain areas is subject to the action mechanisms of natural geographical characteristics, the nature of towns and "human settlements units" construction. Then, adaptive strategies such as the optimization of micro watersheds structures, the establishment of towns compensation mechanism, the multi-functional construction of polder and the division of "waterlogging-control units" are proposed on the three scales of micro watersheds, towns and human settlement units. The purpose is to provide technical support and decision-making basis for disaster risk reduction and quality improvement of human settlements in coastal plain areas of China.
