摘　　要：以中国海域海岛标准名录中辽宁省的633个海岛为研究对象,运用分形理论对其空间形态的分形性质和特征进行探讨,结果表明:海岛面积的标度-频度分形关系、海岛形状指数的标度-频度分形关系和海岛周长-面积分形关系是客观存在的,均具有分形性质,分形维数分别为0.3534、5.0566和1.0871,海岛空间形态的稳定性指数为0.4129,总体而言辽宁省海岛空间形态较简单、但稳定性好。Taking the 633 islands in Liaoning Province listing in the Standard List of Islands in China’s Sea Area as the research objects,we used fractal theory to discuss the fractal properties and characteristics of their spatial morphology.The results show that the fractal relationships of scale-frequency of island area and scale-frequency and circumference-area of island shape index are objective existing.The fractal dimensions are 0.353 4,5.056 6 and 1.087 1 respectively.And the stability index of island spatial morphology is 0.412 9.Generally speaking,the spatial structure of islands in Liaoning Province is simple,but good at stability.
