摘  要:
水产养殖业在我国急速发展,大量的优质海域被占用,海岸景观遭到了破坏。为合理利用近海海域资源,降低养殖业发展带来视觉冲击,该研究以柘林湾和南澳岛的为例,从养殖设施对景观的视觉污染角度出发,运用GIS的视域分析功能,计算研究区6种视域出发点的可视范围,对6种可视域赋予不同权重,叠加分析得出研究区海域和陆域的养殖设施可视几率分布图,为养殖设施的选址方案提供指引。该研究验证了利用GIS视域分析技术应用于视觉影响下的养殖设施选址的可行性,为养殖规划提供了新的科学依据。

摘  要:
Aquaculture develop rapidly in China,causing a large amount of high quality sea area being occupied,and the coastal landscape and seascape destroyed. Aimed at reasonable utilization of coastal sea area resource,reducing the visual impact of aquaculture development,this paper using the GIS viewshed analysis tool to calculate Boolean viewshed of six types of viewpoints,and the six Boolean viewshed were then combined using weighted overlay to produce the overall visual probability distribution for guiding aquaculture site selection of the study area—Zelin Bay and Nanao Island. This paper verifies the feasibility of applying the GIS viewshed analysis technology into aquaculture site selection which focusing on visual impact,and provide a scientific basis for the aquaculture management.
