Study On Service Value Of Island Ecosystem Based On Emergy Analysis

With the further development of the marine development strategy,the development and construction of the island area are increasing,and the regional economy is developing rapidly.However,the accompanying ecological environment and the contradiction between the human economy and the society and the increase of the Japanese drama are of great practical significance to enhance the people's understanding of the ecological environment of the island and to strengthen the scientific development of the island.Zhoushan is the only prefecture level city in China established by the archipelago.Through the study of the ecosystem service value of Zhoushan,it has important reference significance for the island area to maintain the stability of the ecological environment and realize the scientific management at the same time.Based on a comprehensive overview of the research progress in related fields,this paper systematically analyzes the service value of island ecosystem in Zhoushan.Based on the previous research results,this paper tries to use the method of energy analysis to study the service value of Zhoushan island ecosystem,explore the ecological service value and sustainability of the island ecosystem,analyze the status of the ecosystem service value in Zhoushan and the sustainable utilization,in order to put forward the suggestions for the sustainable utilization of the island ecosystem service value in the future.The innovation and deficiency of this study are put forward.Based on the above methods and research,the final results show that the annual energy value of Zhoushan ecological service is 1.10E+23sej,the value of RMB is 12 billion 214 million yuan and the service value of unit area is 5510.24 yuan,with 2016 as an example.From the data and conclusion,in the service value of Zhoushan ecosystem,tourism and leisure value accounted for the highest proportion,accounting for 51.12% of the total value,the proportion of service contribution value of scientific research education is small,only 0.65% of the total value.It shows that the Zhoushan ecosystem is maintained in a relatively stable state in a certain dependence on the outside world,which means that on the one hand,the economic system in Zhoushan will not have a big decline,but on the other hand,the system is very dependent on the environment,and the impetus of the natural environment to the development of the economy is decreasing,and the further development needs to increase the investment in the environmental protection.At the same time,the perspective of the environmental protection will be increased.We should turn more to the economic system and increase investment in human social economy and labor.
