To accurately capture how the public values marine environmental management, we need valuation approaches that can accommodate the complexity of environmental systems and human interaction with them. Coherently representing this complexity in an evaluation means that we can inform the socially optimal allocation of marine resources among competing uses, such as fisheries, industry, and environmental protection. Integrated choice experiments (ICE) provide a systematic approach to valuing large numbers of attributes, and we use them to value eight marine ecological and recreational features at Moreton Bay, South-East Queensland. The ICE employed two sub-experiments: ecological and recreational, to reduce cognitive load for respondents. We compare the ICE approach with a full-profile discrete choice experiment (DCE), with all eight attributes. The ICE had greater face validity than the traditional format. We find large, positive willingness to pay (WTP) for the provision of recreational features and habitat protection, although with some diminishing marginal effects.

激发复杂海洋系统管理的公共价值：综合选择实验

为了准确捕捉公众对海洋环境管理的评价，我们需要能够适应环境系统复杂性和人类与它们互动的估值方法。在评估中连贯地表达这种复杂性意味着我们可以为渔业、工业和环境保护等竞争用途之间的海洋资源的社会优化分配提供信息。综合选择实验 (ICE) 提供了一种评估大量属性的系统方法，我们使用它们来评估昆士兰东南部摩顿湾的八个海洋生态和娱乐特征。ICE 采用了两个子实验：生态和娱乐，以减少受访者的认知负担。我们将 ICE 方法与具有所有八个属性的完整离散选择实验 (DCE) 进行比较。ICE 比传统格式具有更大的表面效度。我们发现提供休闲功能和栖息地保护的巨大积极的支付意愿 (WTP)，尽管边际效应有所减弱。
