This study aims to analyse sea use landscape patterns on a regional scale based on methods of landscape ecology integrated with sea use spatial characteristics. Several landscape-level analysis indices, such as the dominance index, complex index, intensivity index, diversity index and sea congruency index, were established using Geographic Information System (GIS) and applied in Huludao, China. The results indicated that sea use landscape analysis indices, which were created based on the characteristics of sea use spatial patterns using GIS, are suitable to quantitatively describe the landscape patterns of sea use. They are operable tools for the landscape analysis of sea use. The sea use landscape in Huludao was dominated by fishing use with a landscape dominance index of 0.724. The sea use landscape is a complex mosaic with high diversity and plenty of fishing areas, as shown by the landscape complex index of 27.21 and the landscape diversity index of 1.25. Most sea use patches correspond to the marine functional zonation plan and the sea use congruency index is 0.89 in the fishing zone and 0.92 in the transportation zone.
本研究旨在基于景观生态学方法并结合海域使用空间特征，在区域尺度上分析海域使用景观格局。利用地理信息系统（GIS）建立了优势度指数、复杂度指数、集约度指数、多样性指数和海域一致性指数等多个景观层面的分析指标，并应用于中国葫芦岛市。结果表明，基于GIS利用海域使用空间格局特征创建的海域使用景观分析指标，适用于定量描述海域使用的景观格局。它们是进行海域使用景观分析的可操作工具。葫芦岛市的海域使用景观以渔业用海为主，景观优势度指数为0.724。海域使用景观是一个复杂的镶嵌体，具有高度的多样性和大量的渔业区域，景观复杂度指数为27.21，景观多样性指数为1.25。大多数海域使用斑块符合海洋功能区划方案，渔业用海区的海域使用一致性指数为0.89，交通用海区为0.92。
