Optimization of evaluation method of marine resources and environmental carrying capacity based on scientific management and control

Establishing the monitoring and early-warning mechanism of resources and environmental carrying capacity is an important foundation for national major function oriented zoning strategy, and also is a major task of comprehensively deepening reform of central government.Based on test evaluation of Zhejiang province, some problems of marine resources and environmental carrying capacity of the "Trial Method" were found, i.e.the evaluation units have large scale differences, some indicators have obvious regional liquidity characteristics, some fields can't find out overload reasons clearly, resource development benefits is difficult to evaluate, which may affect the scientificalness of the evaluation and the precision, efficiency and fairness of management and control measures.Therefore, the paper proposed optimization suggestions as references for improving the "Trial Method" from the aspects of establishing scientific management and control implementation, including optimizing basic and special evaluation indicators, re-dividing marine fishery and environment evaluation units, highlighting the degree changes of resource utilization and environment damage in process evaluation, refining overload classification, considering regional differences in parameters and thresholds designing.
