Scientific evaluation of tourist satisfaction could contribute to the sustainable development of wetland ecotourism. With the development of Web 2.0, online travel reviews increase significantly which provide valuable information for evaluating tourist satisfaction. Hence, this study aims to evaluate the tourist satisfaction of wetland ecotourism in Zhalong National Nature Reserve (ZNNR) based on online travel reviews. Tourist satisfaction evaluation model and sentiment analysis were applied to calculate satisfactions of evaluation factors that were uncovered based on latent dirichlet allocation model. The results suggest that total satisfaction was 0.614, at the fundamentally satisfied level. Moreover, we identified 11 controllable evaluation factors that were key for ZNNR to manage interaction with tourists, and further aggregated these factors into three categories: ecotourism experience, natural resource and cultural resource. Especially, importance-performance analysis further identified the most important evaluation factors according to four-quadrant weight-satisfaction matrix. The proposed analytical framework expands the understanding of the methodological challenges and offers novel perspectives for evaluating the tourist satisfaction. These findings could provide useful insights for the sustainable development of ecotourism and effective management of wetlands.

对游客满意度的科学评估可以促进湿地生态旅游的可持续发展。随着Web 2.0的发展，在线旅行评论大大增加，这为评估游客满意度提供了有价值的信息。因此，本研究旨在基于在线旅行评论来评估扎龙国家自然保护区（ZNNR）的湿地生态旅游的游客满意度。应用游客满意度评价模型和情感分析方法，基于潜在狄利克雷分配模型，计算出未发现评价因子的满意度。结果表明，总的满意率为0.614，处于基本满意的水平。此外，我们确定了11个可控制的评估因素，这是ZNNR管理与游客互动的关键，并将这些因素进一步归为三类：生态旅游经验，自然资源和文化资源。特别是，重要性表现分析根据四象限权重满意矩阵进一步确定了最重要的评估因素。拟议的分析框架扩大了对方法挑战的理解，并为评估游客满意度提供了新颖的视角。这些发现可以为生态旅游的可持续发展和湿地的有效管理提供有益的见解。拟议的分析框架扩大了对方法挑战的理解，并为评估游客满意度提供了新颖的视角。这些发现可以为生态旅游的可持续发展和湿地的有效管理提供有益的见解。拟议的分析框架扩大了对方法挑战性的理解，并为评估游客满意度提供了新颖的视角。这些发现可以为生态旅游的可持续发展和湿地的有效管理提供有益的见解。
