中国海洋经济地域系统的研究， 是人地关系地域系统研究的重要内容。论文从人地关系地 域系统为切入点， 探讨中国海洋经济地域系统的特征。论文首先分析了中国的海洋资源， 海洋产 业以及海洋经济的发展过程， 海洋经济在国际上所处的地位及在全国经济中的比重。进一步分析 了中国海洋经济在时间上和空间上的演变状况。在研究中应用了主成份分析等数量方法， 对海洋 经济发展年际之间的综合实力水平进行评估， 并绘出了海洋经济总值与海洋产业之间的平滑曲 线， 以此了解各类海洋产业的线性增长趋势。根据海洋经济三次产业的发展， 分析了海洋三次产 业的变化过程， 并利用三轴图法绘制海洋三次产业结构演进过程。为了反映中国海洋经济地域系 统不同类型的差异， 应用主成份分析方法对沿海各海洋经济省市进行综合实力评估并进行排序， 在此基础上划分出不同综合实力水平的海洋经济类型区。

The research on marine economic area system is the most important part in manearth relationship area system in China. This paper discussed the characters of marine economic area system from the point of man- earth relationship area system. Firstly the paper analyzed the marine resources, marine industry and the development process of China. Then the author analyzed the developing condition of marine economy based on space and time changing. What's more, this paper evaluated comprehensive strength of marine economy over years by using some econometric methods such as principal component analysis, and drew the smooth curves between the total value of marine economy and marine industries, which gave the linear trend of the increase of marine industries. According to the development of marine industries, the author analyzed the character of marine industries and drew a tri- axial map to analyze the developing process of marine industry. At last, in order to reflect the differences between different area systems of Chinese marine economy, the author used the method of principal component analysis to give an evaluation and classification of comprehensive strength of coastal province and cities. Based on this result, some marine economic regions are classified according to the comprehensive strength.
