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。
Abstract:
The ecological stoichiometric characteristics of plants and soil in urban wetland system(e.g.ditches)in hilly areas could improve the understanding of plant ability in nutrients absorption and purification, as well as their adaptability to environment.In this study, plant diversity was investigated in three ditches in Shangluo city located at Qinling Moutain area.The contents of total carbon(C), nitrogen(N), and phosphorus(P)in the soil, and roots and leaves of main plant species were measured.Results showed that the contents of soil C, N, and P were equivalent, higher and far below the national average, respectively.This indicated the existence of nutrient imbalance in ditch soil.The average contents of C, N, and P in natural plant leaves were 384.13(±19.35), 24.65(±7.64)and 1.62(±0.53)mg/g.The element contents in leaves were significantly higher than that in the roots and soil.The ratios of C:N, C:P, and N:P in the leaves were 17.06(±7.20), 256.49(±78.59)and 16.05(±5.85).The C:N and C:P ratios were lower than the national average, which indicated a low efficiency of carbon fixation and P constraints in the natural plant growth in the study area.The soil N content was significantly correlated with the plant N content(P>0.05), while the contents of C and P, and the ratios of C:N and N:P in soil were not significantly correlated with these in the plants.This suggests that soil N content might affect N content in the plants, and in turn soil N content could be affected by plant litter.The results also indicated that soil-vegetation nutrition interactions and redistribution pattern should be significantly affected by the way of nutrients absorption by the plants.
