Ecological Research Of Zhejiang Marine Based On Panel Data

Zhejiang has vast sea area and many islands.The total area of the whole province and the exclusive economic zone is about 260 thousand square kilometers.The coastline includes the total length of the island coastline,about 6500 kilometers,accounting for 20.3% of China's total,ranking the first place in China.The mainland coastline is 2200 kilometers,ranking fifth in China.The rapid development of the marine economy has brought unprecedented opportunities for the economic development of the whole province.The marine species resources are rich,and there are various kinds of biological diversity,which provide an important material basis for the development and ecological construction of the province's marine economy.However,the development of the marine economy has also posed an important challenge to the marine ecological environment.The basic research in the scholars,expounds the connotation and characteristics of marine ecological security,after following the index selection principle of evaluation and comparison of the merits of the model,constructs the model of comprehensive index system based on panel data,and through the analytic hierarchy process,a comprehensive evaluation of the general state of Zhejiang marine ecological security for nearly five years.The results showed that the overall index of marine ecological security in Zhejiang increased and fluctuated occasionally,and the marine ecological security in Zhejiang is in general condition.According to the analysis results,the marine economic subsystem,social subsystem,ocean marine ecological subsystem is summarized and some mathematical,finally from the prevention and control of marine pollution,restoration of ecological environment,establish and improve the marine early warning mechanism,optimizing the industry structure,the construction of marine ecological protection zone,the establishment of clear property rights system put forward the ocean several suggestions.
