Abstract: From the perspective of ecological civilization and green economy, this paper has extensively selected the evaluation indicators related to ecological port. Based on a refined analysis of the pressure-state-impacts factors on ecological port, the ecological port evaluation indicator system which contains a hierarchy structure with criteria, factors and indexes is established. Following the principles of purposiveness, feasibility and observability and using the methods of r-cluster and coefficient of variation, the ecological port evaluation indicators are screened with the combination of qualitative and quantitative analysis. Then, the ecological port evaluation indicator system is improved by the application of experts' subjective analysis. The results reveal that final ecological port evaluation indicator system has been proven that it can use 21.30% of initial indicators to reflect 93.91% of original information.
