Abstract:In order to explore the seasonal variations of carbon (C),nitrogen (N)and phosphorus(P)
stoichiometric features in leaves of different natural secondary forests and understand the strategies of plant
adaptation to the environment,we chose Piuns tabulaeformis and Quercus wutaishania natural forests in
Ziwuling Forest district as study area,and subsequently investigated their C,N and P stoichiometric parameters in
leaves from April to October.The results showed:(1)Leaf C,N and P contents and stoichiometric ratios of
P.tabulaeformis were 48.06%,1.15%,0.11% and 42.58,473.22,11.02,respectively,and the same
parameters for Q.wutaishania were 43.16%,2.10%,0.19% and 25.47,380.18,14.49,respectively.
There were less seasonal dynamics in leaf C contents and more seasonal dynamics in leaf P contents than otherthrough the whole growth season.(2)Leaf C content of P.tabulaeformis significantly decreased from April
to June,then remained stable,but it significantly increased from August to October,which was almost equal
to April;while leaf C content of Q.wutaishania was almost constant.Leaf N content of P.tabulaeformis
remained stable before June,then significantly decreased from June to August,then it significantly increased
from August and in October,it was almost equal to April.Leaf N content of Q.wutaishaniasignificantly
decreased from April to June,then remained stable,but it significantly decreased again from August and
reached the lowest value in October.Leaf P content of P.tabulaeformis remained stable before August,
then significantly increased and reached the maximum value in October.Leaf P content of Q.wutaishania
significantly decreased from April to June,then remained stable.The changes of C∶N,C∶P of two species
were averse to their N,P contents.Leaf N∶P of P.tabulaeformis significantly decreased from April to
June,then significantly increased,and it significantly decreased from August to October.The N∶P of Q.
wutaishaniaincreased significantly and reached the maximum value before June and then significantly
decreased.(3)Factorial analysis showed that leaf C contents and C∶N mainly determined by tree species.
For other parameters,they were mainly affected by the interaction between tree species and month.(4)Leaf
C contents of P.tabulaeformis significantly higher than that of Q.wutaishania,however,leaf N content of
P.tabulaeformis was significantly lower than that of Q.wutaishania,therefore,leaf C∶N of P.tabulaeformis
was significantly higher than that of Q.wutaishania.However,leaf N∶P of Q.wutaishania was
significantly higher than that of P.tabulaeformis.There was no significant difference in leaf P content and
C∶P between these two species.The coefficient of seasonal variation of leaf N,P contents and C∶N,C∶P,
N∶P of P.tabulaeformis were smaller than those of Q.wutaishania.The results could enrich the study of
ecological stoichiometry in natural forests,and provide a theoretical basis for the forest restoration and
management in the hilly and gully region of Loess plateau.
