| 摘 要： | 应用灰色系统理论,综合考虑近海海域水质指标、沉积物指标、生态系统结构指标,在提出近海海洋生态系统健康评价标准的基础上,建立灰色系统法综合评价近海海洋生态系统健康模型;利用灰色系统综合评价法与污染指数评价法对渤海海域四个不同监测点的实际调查结果分别进行计算,计算结果表明两者之间具有一定的一致性,从而,初步证明灰色系统评价模型应用于近海海洋生态系统健康评价具有可行性.

| Abstract: | A criterion of assessment was provided on the health of sublittoral marine ecosystem, considering with multi-index of water quality,sediments quality and ecosystem structure and function.Then,an integrated indicators assessment model was established basing on grey system method.This model was proved to be feasible on the assessment of sublittoral marine ecosystem health with comparing the study results of Grey System Method (GSM) and Pollution Index Number Method(PINM). |

| Keywords: | ecosystem health grey system pollution index |
