Endangered plants are essential components of most forest ecosystems and reflect the ecological integrity of forests. The study of the population structure and spatial pattern of Alsophila spinulosa is of great significance for its conservation. In the subtropical Chishui Tree fern valley in China, we studied the best structure of A. spinulosa to reflect the environmental change, the range of the most intense spatial aggregation change, and the spatial relationship with the community structure, and explored the survival characteristics of A. spinulosa. Our results showed that the variation in tree height structure was the most obvious response to the change in community type. The spatial aggregation degree of A. spinulosa had the most obvious change in the range of 1–5 m. There was an obvious spatial correlation between the dominant plants, the vertical structure of the community, and the distribution of A. spinulosa. These findings provided a reference for exploring the population structure, distribution pattern, and the influence of community types on A. spinulosa populations.
