摘要:
探究山区城市沟渠湿地环境中植物与土壤中CNP生态化学计量特征,对于揭示植物对营养元素的吸收、净化以及植物对环境的适应与反馈能力,指导沟渠植被恢复重建和山区城市规划具有十分重要的意义。在秦岭山区的商洛市三条沟渠中测定了植物多样性及主要植物根、叶、土壤的C、N、P含量。结果显示:秦岭山区城市沟渠土壤C与全国平均水平相当,N含量高于而P元素含量远低于全国的平均水平,表现出沟渠土壤养分元素含量的不平衡。自然植被叶片C、N、P的平均含量分别为384.13(±19.35)、24.65(±7.64)和1.62(±0.53)mg/g,叶的元素含量显著高于根和土壤; C:N、C:P及N:P分别为17.06(±7.20)、256.49(±78.59)、16.05(±5.85)。C:N和C:P之比低于全国平均水平,说明该地区城市沟渠自然植被固C效率低,沟渠植物的生长受到P限制。土壤与植物的N含量存在显著的正相关关系(P<0.05),而C、P、C:N、C:P、N:P间的相关性并不显著(P>0.05),表明土壤的N含量影响植物体中的含量,同时土壤含量也受到植物凋落物的影响。植物对元素的吸收利用显著影响着土壤-植被间元素的相互作用和再分配模式。
