Research and Application of Coastal Building Setback line Delimitation Method Based on System Dynamics

Abstract

The paper clarified the basic principles of coastal setback line delineation: to adhere to the people-oriented concept of sustainable development, to protect the stock of resources development red line, environmental and ecological security red line can not be touched, consider the intergenerational effects of resource development and environmental pollution, leaving reserves and space for the sustainable development of future generations. On this basis, the motion model of coastal system was constructed as the basis for determining the backline of coastal buildings. The results of practice in Taizhou City showed that the order of coastal system movement in coastal counties (cities and districts) was Sanmen County, Linhai City, Luqiao District, Jiaojiang District, Wenling City and Yuhuan City. The amount of land and sea resources development was positively correlated with the amount of coastal system movement, negatively correlated with the output value, the greater the amount of coastal system movement, the lower the efficiency of resource development. The amount of coastal system movement was positively correlated with the distance of building setback. This paper was of reference significance in enriching the theoretical connotation of coastal building setback line and improving the calculation method of coastal building setback distance.
