雅安不同海拔地区的珙桐群落土壤养分特征
|
摘要
为了探究珙桐群落在雅安不同海拔地区的梯度土壤的化学计量特征,阐明珙桐群落土壤性质对海拔变化的响应规律,进而有效指导珙桐群落的保护,在雅安的珙桐群落分布带上选取了1 000 m～1 500 m、1 500 m～2 000 m和2 000 m～2 500 m 3个海拔梯度,测定海拔1 000 m～2 500 m范围内土壤pH值和养分含量,计算并分析土壤C∶N、C∶P、C∶K、N∶P、N∶K和P∶K。结果表明:(1)雅安的珙桐群落土壤中有机碳、全氮、全磷和全钾变化范围分别为7.08 g·kg~(-1)～86.26 g·kg~(-1)、0.73 g·kg~(-1)～5.74 g·kg~(-1)、0.27 g·kg~(-1)～1.77 g·kg~(-1)和20.56 g·kg~(-1)～70.37 g·kg~(-1),且随着海拔梯度的增加土壤中有机碳、全氮、全磷、全钾含量增加。(2)土壤中C∶N、C∶P、C∶K、N∶P、N∶K和P∶K范围分别为8.91～33.98、22.25～78.06、0.17～3.53、1.47～5.80、0.02～0.23和0.01～0.06。随着海拔梯度的增加,土壤中C∶N、C∶P和N∶P变化趋势类似,随着海拔梯度的增加先增加后降低,土壤中C∶K、N∶K随着海拔梯度的增加而增加,土壤中P∶K在不同海拔梯度下变化趋势不大。
The elevations of 1 000 m～1 500 m,1 500 m～2 000 m and 2 000 m～2 500 m were selected in order to explore the soil stoichiometric characteristics and the response regularity of Davidia involucrata communities in different altitndes in Ya'an City by measuring Soil pH and nutrient contents,calculating and analyzing soil C∶N,C∶P,C∶K,N∶P,N∶K and P∶K.The results were as follows:(1) the soil organic carbon,nitrogen,phosphorus and potassium were 7.08 g·kg~(-1)～86.26 g·kg~(-1),0.73 g·kg~(-1)～5.74 g·kg~(-1),0.27 g·kg~(-1)～1.77 g·kg~(-1) and 20.56 g·kg~(-1)～70.37 g·kg~(-1) respectively,and these contents increased with the increase in elevation.(2) Soil C∶N,C∶P,C∶K,N∶P,N∶K and P∶K ranged between 8.91～33.98,22.25～78.06,0.17～3.53,1.47～5.80,0.02～0.23,and 0.17～3.53 respectively.With the increase in elevation,the changes of C∶N,C∶P and N∶P were similar in soil.The soil C∶K and N∶K increased with the increase in elevation,the change trend of soil P∶K was not significant under different elevation gradients.
