摘　　要：论文组合采用变异系数、基尼系数、泰尔指数三种空间差异分析方法,从不同空间尺度剖析了海洋渔业时空分异演化特征,采用Pearson相关系数对典型影响因素与海洋渔业的关联特征进行分析。结果显示,2005-2015年海洋渔业产值总体规模持续增长,省际间空间差异显著,总体差异略有下降,人均海洋渔业产值变异系数和基尼系数分别由0.952下降到0.911、0.543下降到0.528,泰尔指数则由0.274下降到0.269;环渤海、长三角和珠三角三大沿海地区海洋渔业产值总体呈南北高中间低的分布态势,三个地区内部的空间差异表现为珠三角>环渤海>长三角,其中长三角和珠三角地区空间差异呈降低趋势,环渤海地区呈上升态势;海洋渔业对资源条件和服务支撑要素依赖性强,大陆海岸线长度、海域面积和沿海渔港情况3种因素与海洋渔业产值空间格局显著相关。The Variation coefficient, Gini coefficient and Theil index was employed to analyze the spatial and temporal disparities of marine fishery from different spatial scales. Pearson correlation coefficient was used to analyze the correlation characteristics between typical factors and marine fishery output. The results showed that the marine fishery output continued to grow from 2005 to 2015. The Variation coefficient and Gini coefficient of per capita marine fishery output decreased from 0.952 to 0.911, 0.543 to 0.528, respectively. The Theil index fell from 0.274 to 0.269. The distribution of marine fishery output in the three areas (the Bohai Rim region, the Yangtze River Delta, the Pearl River Delta) was characterized with status of north-south-high and middle-low. The inner disparities of the three regions showed the Pearl River Delta > the Bohai Rim region >the Yangtze River Delta. The Yangtze River Delta and the Pearl River Delta showed a downward trend, the Bohai Rim region upward. This study had shown that marine fishery relied heavily on resource conditions and service support factors, especially with the continental coastline length, sea are a and coastal fishing port situation.
