The Enlightenment of the Present Situation of Marine Environment in Zhejiang Province to the Relevant Development Requirements in the New Period

In the new era,the development level of marine industry in Zhejiang province has been improved rapidly,and a series of marine development concepts and requirements have been implemented one after another,which plays an important role in improving the current situation of marine environment.With the deepening of marine development,the current situation of marine environment in the new era has become complex and diverse.How to make the relevant concepts and requirements of marine development to cope with and adapt to various new problems in the development process has become the key to promote the continuous improvement of marine development level.

Standardization Framework of Marine Sustainable Development Evaluation System

The core concepts of standardization framework of marine sustainable development evaluation systemare fairness and justice and the aim of sustainable development is to pursue development beneficial bothfor the current and future generations.Scientific evaluation of sustainable marine development is importantfor ensuring an accurate level of marine development.Establishing a scientific evaluation system is of greatimportance in the planning of marine development.Standardization of such an evaluation system needs tobe based on comprehensive work and must be founded on both marine science and modern managementprinciples.This paper analyses the current marine standards situation and looks at the assessment systemfor marine sustainable development.It also lists the main reasons for the standardization of a sustainablemarine development evaluation system and analyses five existing marine standardization problems whichare a constraint to this standardization.Finally a framework of marine sustainable development evaluationsystem standardization is established.The conclusion incorporates some advice on how to promote thisstandardization.

Preface for Special Issue on“Key Mechanical Problems of Marine Energy Development Equipment”

There are abundant energy reserves such as oil,natural gas,hydrate,and wind energy in the ocean.Countries around the globe are competing to advance their marine energy development technologies.The exploitation of marine resources relies on cutting-edge industrial equipment.After decades of R&D endeavors,China has obtained most of the key technologies for the design,production,testing,and field application of marine energy development equipment(Xie and Zeng,2021).

Looking for a Chinese solution to global problems:The situation and countermeasures of marine plastic waste and microplastics pollution governance system in China

As one of the top ten environmental problems to be solved in the world,marine plastic waste and microplastic pollution seriously affect the health of marine ecosystems and the sustainable development of Marine economies.It is necessary to promote the establishment of a scientific and systematic Marine plastic waste and microplastic pollution control system and take strong measures to fundamentally curb and reverse the trend of marine pollution intensification in China.This paper first explains the practical significance of marine plastic waste and microplastic pollution control from three aspects:the sustainable development of the blue economy,the structural upgrading of the pan-plastic industry,and the improvement of public health awareness.Secondly,the particularity of marine plastic waste and microplastic pollution control system is summarized from three aspects of formation mechanism,migration path and damage performance.Then,it identifies domestic and international governance strategies and action plans from the perspectives of mechanism,subject,object,and measures,summarizes existing problems in the existing marine plastic waste and microplastic pollution control system,and gives directions for future improvement.Finally,some countermeasures and suggestions are put forward to accelerate the construction of China’s marine plastic waste and microplastic pollution control system,including the formation of a cross sectoral integrated land and sea control system,a full life cycle waste management process,a multi-participation model for marine ecological and environmental governance,and a global marine pollution prevention and control system.

Evaluation and Driving Force Analysis of Marine Sustainable Development based on the Grey Relational Model and Path Analysis

With the rapid development of the marine economy,the demand for marine resources development and the pressure on marine environmental protection are gradually increasing.It is critical to evaluate and analyze the driving forces of marine sustainable development in order to promote the coordinated development of the marine economy,resources and environment.Taking Jiangsu Province of China as an example,this paper constructs an evaluation index system for marine sustainable development from the three aspects of marine economy,resources and environment,and calculates the weight of the variation coefficient for each indicator.Based on the grey relational model,the average value of the relational degree,calculated by the average value method of correlation coefficients and the weighting method,is then used to evaluate the status of marine sustainable development in this province.The comprehensive index model is used to analyze the dynamic trend of the evolution of marine sustainable development.The driving forces of marine sustainable development are analyzed by the path analysis method combined with the average values of the grey relational degree for each indicator.This analysis found that the marine sustainable development in 2016 and 2012 was good,the situation in 2007 was bad,and the remaining years were intermediate.Compared with the previous years,the optimal conditions of 2008 and 2012 were obvious.The main driving factors of marine sustainable development are cargo throughput of coastal ports,economic losses caused by storm surges in coastal areas,the area of marine nature reserves in coastal areas,coastal wind power generation capacity,and marine biodiversity.
