Abstract. -俄亥俄州构造两个人工珊瑚礁在洛雷恩和凯霍加县从1986年开始。珊瑚礁是一个示范项目评估珊瑚礁渔业的影响满意度和礁建设在其他领域的可行性。珊瑚礁的影响评价必不可少的娱乐活动被视为进一步礁在俄亥俄州和其他大湖国家发展。双管齐下的研究工作是:一个水下视频调查和旅行成本研究。旅行成本研究估计的经济价值来源于使用洛雷恩县礁运动垂钓者和潜水员。本研究的结果支持的关键施工的大型人工礁海岸在克利夫兰(凯霍加县)用碎石从旧的克利夫兰体育场。从850年4月至1992年10月,那些愿意参与在洛雷恩县联系码头和发射坡道。早在1993年2月,这些人邮寄问卷,第二个问卷寄给nonrespondents在2月底。百分之五十五的回应。我们估计三个替代单个方程旅行成本模型。 The most conservative estimate of consumer surplus (economic value) showed that the typical angler who used the reef in 1991 made nearly 10 more fishing trips during 1992 than the typical angler who did not use the reef in 1991, that is, nearly 26 trips in 1992 compared to 16 trips in 1992 by those who did not use the reef in 1991. The most conservative estimate of consumer surplus also showed that anglers who used the reef before 1992 valued total angling activity at US$302 more for the year 1992 than anglers who did not use the reef before 1992. When aggregated across all Lorain County anglers using the reef during 1991, the total value of the reef was $276,000 in 1992 compared to total construction costs of less than $100,000. Thus, the consumer surplus generated by the reef in one year exceeded construction costs by a wide margin.
