Study On The Environmental Quality Evaluation Of Human Settlements In Coastal Tourism Cities

China is a country with long coastline.Coastal tourism is developing rapidly.Coastal tourism cities are especially places which tourists are longing for.More and more tourists are heading for the beachfront.This has brought tremendous ecological pressure and pressure of living on coastal tourism cities,resulting in human settlements.Environmental issues,the quality of human environment are getting more and more attention.The quality of human environment has become an important indicator of people's evaluation of living standards.In this context,the study of the quality of human environment in coastal tourism cities not only can improve the theoretical support of the human environment,but also explore the road to the construction of human environment in coastal tourism cities,and it can also have a positive impact on the healthy development of human environment in coastal tourism cities.A certain degree of reference can also provide residents with a better place for living,and provide a reference for the development and research of human environment in the same type of coastal tourism cities in China.The evaluation indicators were screened by the Delphi method,and the AHP obtained the weight of each indicator.Then the data of each indicator was standardized and the result of human environment quality evaluation was obtained by using a linear weighted summation model.The evaluation results show that:from the point of view of changes in the human environment quality of each coastal tourism city,the overall situation is constantly improving.The quality of human environment in Xiamen has been constantly improving,and the trend towards better in the later period has become evident.In recent years,the quality of human environment in Xiamen has improved significantly.Sanya City has been ranked first since 2014,and the trend is getting better.It has the same effect as Xiamen City.While the comprehensive evaluation value of Zhoushan City continues to increase.However,late-stage growth has slowed down and there has been a downward trend.This is a question worth pondering.Finally,based on Dosa Diaz's "human settlement" theory,ecological community theory,ecological city construction theory,sustainable development theory and foreign experience etc.From four aspects,the suggestions for the optimization of human settlement environment quality in coastal tourism cities have been put forward:coastal ecological environment protection,multi-participant human settlement culture construction,urban prosperity economic construction and the acceleration of a sound social security system.
