Abstract

Abstract: We conducted an experiment in four different elevation sites in Wuyi Mountains in a subtropical region. We measured the fine root biomass and fine root length, analyzed the fine root special root length seasonal dynamic. The results showed that:(1) Special root length of living fine root (LFRSRL) of both 0—10 cm and 10—25 cm soil layers was alpine meadows>dwarf forest>coniferous forest>evergreen broadleaf forest, which had very significant difference at different elevation (p<0.01). (2) Special root length of living fine root in 0—10 cm soil was higher than that in 10—25 cm soil layers of evergreen broadleaf forest and coniferous forest, but in 10—25 cm soil layers was higher than that in 0—10 cm soil layers of dwarf forest and alpine meadows. Special root lengths of living fine root and dead fine root had no significant difference at different soil layers (p>0.05).(3) Special root lengths of living fine root and dead fine root in both 0—10 cm and 10—25 cm soil layers of each forest displayed seasonal dynamic at different degree, but there was no significant difference in different seasons (p>0.05).
