皖南次生马尾松林恢复过程中林下木本植物生长动态及性状响应
Growth dynamics and trait responses of understory woody plants during the restoration of secondary Pinus massoniana forests in southern Anhui
摘要
Abstract
Using a space-for-time substitution approach,we examined leaf traits,wood density,and growth rates of dominant woody species in the understory of Pinus massoniana forests at 10-,20-30-,and 50-year restoration sta-ges in the Guniujiang Nature Reserve,Anhui Province.We found that:(1)Plant functional traits varied signifi-cantly among restoration stages.Early-stage forests(10 years)were characterized by higher leaf nitrogen and phos-phorus concentrations,higher growth rates,and lower wood density,whereas late-stage forests(50 years)exhibi-ted longer leaf lifespans and higher wood density.(2)The co-occurring species Eurya muricata and Loropetalum chinense showed gradual increases in specific leaf area and decreases in leaf thickness across the restoration chrono-sequence.(3)The biomass increment of understory woody species was significantly positively correlated with leaf nitrogen content per unit mass(Nmass),leaf phosphorus content per unit mass(Pmass),total leaf nitrogen content(TN),and total leaf phosphorus content(TP),while the relative growth rate of basal diameter(RGB)was signif-icantly negatively correlated with wood density.Together,these findings underscore the importance of functional trait dynamics of understory species during forest succession.关键词
