海岛休闲渔业发展优化配置研究——以田横岛为例

Evaluation of Island Recreational Fishery Development Capacity:A Case Study of the Tianheng Island

休闲渔业对于海岛经济发展至关重要,尚有许多开发潜力较大的海岛休闲渔业资源缺乏科学合理的开发规划。本研究采用等比例尺寸栅格化与土地利用类型斑块化相结合的划分方法,在遴选了基础条件、休闲渔业资源和旅游资源现状价值指标,以及岸滩赶海、休闲捕捞、海洋垂钓和渔家体验四种休闲渔业类型提升指标的基础上,应用层次分析法为各指标赋予权重,构建了海岛休闲渔业开发价值评价-提升综合模型,并以田横岛为实例进行了模型验证。模型计算结果表明:田横岛的基础条件得分为2.607分,休闲渔业资源2.806分,旅游资源2.955分,均处于中等水平。模型给出了包括岸滩赶海区域2处、海洋垂钓区域2处、休闲捕捞区域1处和渔家体验区域3处的评价结果,与海岛现状实际较符合,证明该模型具有较好的科学性、适用性和可操作性,模型可用于确定适合海岛休闲渔业发展提升的空间,对于优化配置海岛资源具有重要的参考价值和借鉴意义。

Recreational fishery is important to economic development of an island.Many islands with great development potential of fishery resources are still lack of scientific and reasonable development planning.By using the division method of the combination of fixed size rasterization and land use type patching,we select the current value indicators including basic conditions,recreational fishery resources,tourism resources,as well as and the mining and promotion indicators of four types of recreational fisheries:beach catching up with the sea,recreational fishing,marine angling,and fisherman experience,and give weight to each index by analytic hierarchy process,then construct a comprehensive model for the current situation evaluation,mining and promotion of island recreational fishery,taking the Tianheng Island as an example for verification of the model.The results show that the basic conditions,fishery resources,and tourism resources of the Tianheng Island are general,but there is a large space for improvement.The model gives out the fishery resources suitable for further excavation and improvement,including two beach areas,two marine fishing areas,one leisure fishing area and three fisherman experience areas.The results are consistent with reality,suggesting that the model is practical and has important referential value for the scientific protection and utilization of island fishery resources.
