为了更加合理有效地评价我国海洋资源承载力,分析了我国海洋资源承载力评价的现状及问题、主成分和变化趋势。结果表明：基于主成分分析法的海洋资源承载力研究方法克服了专家打分法的缺陷,它以实际数据为支撑,更为客观地评价出了我国海洋资源承载力近年来的变化趋势,为我国海洋资源承载力的可持续发展提供理论支持。
為瞭更加閤理有效地評價我國海洋資源承載力,分析瞭我國海洋資源承載力評價的現狀及問題、主成分和變化趨勢。結果錶明：基于主成分分析法的海洋資源承載力研究方法剋服瞭專傢打分法的缺陷,它以實際數據為支撐,更為客觀地評價齣瞭我國海洋資源承載力近年來的變化趨勢,為我國海洋資源承載力的可持續髮展提供理論支持。

In order to evaluate marine resource carrying capacity in our country more reasonably and more effectively,the actuality,problems,principal component and variation trend of marine resource carrying capacity evaluation in our country were analyzed.The results showed that the research method based on principal component analysis（PCA） overcome the defect of expert scoring method.Supported by real data,it showed the variation tendency of marine resource carrying capacity in recent years in our country more objectively,and provided theoretical support for the sustainable development of marine resource carrying capacity in our country.
