The analytic hierarchy process (AHP) was used to develop the evaluation system for the ecotourism resources in Yongtai County, in Fujian Province and the weights of all quasi-side layers were determined and ranked. Major conclusions: weight values of the geologic resources and water resources of the county are higher, indicating geospatial resources and water resources are its dominant tourism resources. Then, quantitative evaluation was performed on the main eco-tourism scenic spots in Yongtai County for an empirical study of the evaluation system. The county’s Tianmenshan Scenic Area scored the highest. The geographical resources of all scenic spots ranked first, and the water resources ranked second. The evaluation results are consistent with the actual situations, proving the validity and rationality of the evaluation system. Through evaluation of resources, the advantages and disadvantages of the county's ecotourism resources were determined, and corresponding advices and solutions were provided. The purpose is to give directions for the development of ecotourism in the county and provide references for evaluation and development of ecotourism resources in other regions.
