Based on the integrated assessment methods of marine ecological environment quality, and the survey data in China, an integrated assessment method of ecological environment quality of sea areas around islands was established. Totally 12 indices were selected from environmental and biotic elements to set up an integrated assessment index system, and then 5 classification levels and their evaluation standards were determined. The weights of indices were determined using analytic hierarchy process. 10 representative islands were selected in northern South China Sea according to the characteristics of geographical distribution, around which the ecological environment quality of sea areas were assessed using the above method for case study. The result showed that 8 islands were classified as in ‘Good’ status and the other 2 islands were in ‘Moderate’ status. The northern South China Sea was generally at good status. The ecological environment quality was influenced by the offshore distance, the discharge of land based pollutant, and sea water exchange ability. The integrated assessment method established in this paper was able to objectively reflect the ecological environment status of sea areas around islands.
