In order to provide better references for the protection and development of Phoebe and Machilus plants germplasm resources, community ecology method was used to investigate the Phoebe and Machilus community in Zigui Country, Hubei Province. The distribution of the species, the number of resources and the habitat conditions were recorded, the community characteristics and the impact of different factors on the Phoebe and Machilus community were analyzed, and the correlation rules between the Phoebe and Machilus community and the living environment were revealed. The results showed that the populations of P. chinensis and Machilus pauhoi were significantly more than those of P. zhennan and M. ichangensis, the community structure was more complete and the potential for development was better. The flora composition of Phoebe and Machilus community in Zigui Country was relatively complex, its flora was diverse and abundant, its dominant population was prominent, and the genera of its families were relatively dispersed with some natural regeneration ability. Phoebe and Machilus distribution from the point of view, when the slope was 20°, Phoebe and Machilus distribution was the most ideal slope. In the survey area, the predominance was of angiosperms, especially dicotyledons. The ferns and gymnosperms were relatively poor.

This study explores parental mediation of smartphone use by rural‐to‐urban migrant children in China. A total of 16 migrant parents participated in semi‐structured interviews. Reflexive thematic analysis is conducted to analyse the transcribed interviews. Findings indicate that migrant parents are highly concerned about the harmful impact of smartphone use on their children. Three parental mediation strategies mentioned in previous studies are confirmed, that is, restriction mediation, monitoring and active mediation, whereas a new mediation strategy, namely, activity substitution, is identified in this study. This study finds that the parents use a combination of different strategies for parental mediation. Furthermore, four themes identify the challenges in parental mediation: Lack of time, skills and helper for parenting and father's absence, inconsistency between parents' restrictive mediation and own overuse practices, the adverse effect of COVID‐19 and the need for professional help. Finally, implications for social work practice are discussed.
