Abstract: With the rapid development of ecotourism and owing to the special features of wetland resources, wetland ecotourism has become a research focus. It was considered that different types of wetland should have different ecotourism development models, and the establishment of these models should be based on the analyses of historical and cultural background, integrity of ecosystem, competitive capability of market, and regional economy. In this paper, an analysis model with 16 second class indicators for the development of wetland ecotourism was built, and used in a case study of Yancheng Red Crowned Crane Wetland Nature Reserve in Jiangsu Province, from which, the advantages and disadvantages of developing ecotourism could be found in time. The further development direction of ecotourism was discussed.
