Soil moisture and slope direction dominate plant community distribution in Maotai.
The researchers analyzed plant communities in the Maotai Water Functional District to understand their relationships with the environment. They used TWINSPAN classification and DCA ordination on 57 plant community quadrates. The results showed that 11 association types were identified, with soil moisture and slope direction being key factors in plant distribution. Soil moisture and light intensity were found to be important ecological factors affecting plant distribution. The study also revealed a substitution relation of species within plant communities, indicating similarities in their distribution.
