Abstract

Abstract:

This study explores the response of eco-chemometrics of Pinus yunnanensis to elevation and investigates the relationship between nutrient elements in different organs of P.yunnanensis and soil nutrient elements,providing theoretical support for the management of P.yunnanensis forests.The natural secondary forests of P.yunnanensis at different elevations in Northwest Yunnan were studied,carbon(C),nitrogen(N),phosphorus(P)and their stoichiometric characteristics in different organs and rhizosphere soil of P.yunnanensis at different elevations(1 900 to 2 900 m)were compared.The results showed that the N content of needles was higher than that of fine roots,and the N∶P ratio of both needles and fine roots was less than 14.Additionally,the contents of soil C(13.037 g/kg)、N(1.446 g/kg)and P(0.473 g/kg)were lower than the average levels of topsoil in China.The contents of N,P,C∶N,C∶P,N∶P in rhizosphere soil were significantly affected by elevation,while the nutrient contents and stoichiometric characteristics of needles and fine roots of P.yunnanensis showed no significant changes across elevation gradients.The contents of C and C∶N in needles of P.yunnanensis belong to sensitive steady state and weak steady state respectively,the other indexes belong to absolute steady state.While the contents of C,N,P,C∶N,C∶P,N∶P in fine roots of P.yunnanensis were not significant,all belonging to absolute steady state.The growth of P.yunnanensis in poor soil with low nitrogen and phosphorus,and its growth is mainly restricted by N,but P.yunnanensis adapts to the change of elevation gradient by increasing N absorption into plants and distributing more N into needles P.yunnanensis has good adaptability to the rhizosphere soil environment in the range from 1 900 to 2 900 m.This study revealed the adaptability of stoichiometric characteristics of P.yunnanensis to elevation in western Yunnan,and provides data to support further research on nutrient distribution pattern and environmental adaptability of P.yunnanensis.

Key words: Pinus yunnanensis, needle(leaf), fine roots, rhizosphere soil, stoichiometry, elevation
