为促进旅游业的良性发展，结合生态位理论，从4个维度构建旅游生态位评价指标体系。在此基础上，以四川省18个市2022年统计数据为“态”、2019—2022年的统计数据增长率为“势”，计算其生态位宽度和生态位重叠度。结果表明，18个市的生态位宽度和生态位重叠度均存在明显的差异，其中有6个市的生态位重叠度明显高于均值。为促进四川省旅游产业良性发展，应开发和保护多样化旅游资源以扩充生态位宽度，合理规划和组织地方旅游资源以降低生态位重叠度，促进区域经济协调发展。

In order to overcome vicious competition among tourist destinations and promote the healthy development of the tourism industry,an evaluation index system for tourism ecological niches was constructed based on niche theory from four dimensions. On this basis,using the 2022 statistical data of 18 cities in Sichuan Province as the “state” and the growth rates of statistical data from 2019 to 2022 as the “trend”,the niche breadth and niche overlap degree were calculated.The results show that there are significant differences in niche breadth and niche overlap among the 18 cities,with 6 cities exhibiting niche overlap degrees significantly higher than the average.To promote the healthy development of Sichuan's tourism industry,it is recommended to develop and protect diversified tourism resources to expand niche breadth,and to reasonably plan and organize local tourism resources to reduce niche overlap,thereby promoting coordinated regional economic development.
