Nitrogen (N) and phosphorous (P) stoichiometry in plant leaves have been studied intensively with recent focus on large-scale patterns and driving mechanisms. An experiment was conducted in Hei Lihe of Inner Mongolia Autonomous Region, Song Mountain of Beijing and Taiyue Mountain of Shanxi Province to understand the N and P stoichiometry between Pinus tabulaeformis and broad-leaf trees in nature Pinus tabulaeformis Carr. Leaf stoichiometry showed large variations with N ranged from 0.9344% to 4.8987%, P from 0.0790% to 0.6555%, and N/P from 3.6328 to 35.4302. N and P were significantly and positively correlated (r=0.589, P<0.01), and P was significantly and negatively correlated to N/P (r=﹣0.618, P<0.01). N and P contents of Pinus tabulaeformis were lower than that those observed for broad-leaf trees in three sites. This implies that broad-leaf trees have higher N and P storage capacity than Pinus tabulaeformis. N/P in Pinus tabulaeformis and in broad-leaf trees differed significantly (P<0.01) in Hei Lihe. The mean concentrations of N and P for Pinus tabulaeformis ranked in the order of Taiyue Mountain> Hei Lihe> Song Mountain, while ranked as Hei Lihe> Song Mountain> Taiyue Mountain for broad-leaf trees. The result reveals that Pinus tabulaeformis has the high N and P storage capacity in Taiyue Mountain and that broad-leaf trees has high N and P storage capacity in Hei Lihe.
