岩溶区吊丝竹林生态系统生物量及生态化学计量学特征
|
摘要
以广西马山县岩溶区吊丝竹林为研究对象,分析吊丝竹林各组分的生物量,C、N、P、K含量及其化学计量学特征,揭示岩溶区竹林养分吸收及生态化学计量学的特殊性。结果表明,岩溶区吊丝竹各器官单株生物量大小表现为竹秆、竹枝、竹叶、竹蔸、侧根;吊丝竹各器官的C、N、P、K含量及化学计量比存在显著差异;土壤的C、N、P含量高于全国土壤的平均水平,但C∶N比低于全国平均值;凋落物的N、P含量均小于叶片,但C∶N、C∶P值均高于叶片;植物N∶P值是表示环境中养分制约的重要指标,吊丝竹N∶P值为9.36,表明氮素是吊丝竹植物生长的主要限制因素。
In this paper,the biomass,C,N,P,K contents and eco-chemometrics characteristics of each organ in the Dendrocalamus minor forest were studied in Karst area of Mashan County,Guangxi Province.The characteristics of nutrient absorption and eco-chemometrics of this bamboo forest in Karst area were revealed.The results showed that the biomass of each organ in Karst area was as follows:bamboo stalk > bamboo branch > bamboo leaf>culm stump>lateral root,the contents of C,N,P,K and stoichiometric ratio of each organ were significantly different from each other in this ecosystem.Significant differences in C,N,P,K contents and stoichiometric ratio of each organ were found.The contents of C,N,P in soil were higher than those of soils in China,but the C∶N was lower than the average in China,the contents of N and P in litter were lower than those in leaves,but the values of C,C∶P in litter were higher than those in leaves.The N∶P value of plant is an important index which indicates the nutrient restriction in the environment.The value of N∶P was 9.36 in the study,and nitrogen was the main limiting factor for the growth of D.minor in Karst area.
