Abstract:In this paper the index system,including basic evaluation,specific evaluation and process e-valuation of early-warning of the marine resources and environmental carrying capacity of Tianjin mari-time space was constructed.The study had referred to the relevant research progress domestically and internationally,and the Technical Manual of Resources and Environment Carrying Capacity Monitoring and Early-Warning(Trial)issued by the National Development and Reform Commission of the People's Republic of China had also been referenced.The basic evaluation was used to conduct an overall evalua-tion for jurisdictional maritime area and was measured by nine indicators including three categories:marine space resources,marine fishery resources and marine ecological environment.The specific eval-uation included four indicators and was used to conduct specific evaluations for different major function-al zones,such as optimized development zones and prohibited development zones.The process evalua-tion included five indicators and divided into three categories:the consumption of marine resources,the changes of ecological environment,and the changes of ecological disaster risk.The process evaluation was of-ten used to indicate the variation tendency of the pressure which could vary with the human activities and was shouldered by marine environmental resource.Buckets effec and the analytic hierarchy process(AHP)compre-hensive evaluation were used in this study respectively.The results showed that the evaluation results obtained by the AHP comprehensive evaluation were more in line with the actual situations of Tianjin.The marine re-sources and environmental carrying capacity of jurisdictional maritime area had been overloaded from 2011 to 2019.The evaluation results of marine resources and environment consumption was slowing down,and the early-warning levels of Tianjin were in the slight warning(blue)state.The corresponding measures were put forward according to the evaluation results.The above results could technically help us to carry out the early-warning evaluation of national marine resources and environmental carrying capacity.
