摘要/Abstract

摘要： 采集浙江省龙游县境内毛竹林地不同坡向(阴坡和阳坡)的土壤样品进行对比分析,研究坡向对毛竹林地土壤养分及其生态化学计量特征的影响.结果表明: 土壤养分受坡向和土层深度的影响,采样区内土壤的养分水平呈阴坡＞阳坡、表层土壤＞底层土壤的变化趋势.阴坡土壤的阳离子交换量、总有机碳、全氮、碱解氮、速效磷、全钾和速效钾含量显著高于阳坡,分别高43.7%、103.8%、92.0%、75.5%、22.4%、89.4%和240.7%,而阴坡和阳坡土壤的全磷含量并无显著性差异.0～20 cm、20～40 cm和40～60 cm 3个土层中,无论是阴坡还是阳坡,其土壤C/N差异均不显著,而阴坡土壤C/P显著高于阳坡,分别高180.8%、42.0%和54.3%;各土层中,阴坡和阳坡土壤的C/K和N/K之间的差异不显著,而阴坡和阳坡土壤的C/K和N/K在3个土层间存在极显著性差异.采样区域内阴坡土壤有机碳与全氮、全磷和全钾之间呈极显著的正相关关系,并且与各速效养分间也均呈极显著的正相关关系.总体而言,毛竹林阴坡的土壤养分及其生态化学计量特征优于阳坡.

Abstract: We analyzed the effects of slope direction on soil nutrients and ecological stoichiometry by collecting soil samples from different slope directions (shady slope and sunny slope) of the bamboo forest in Longyou County, Zhejiang Province. The results showed that soil nutrients were affected by slope direction and soil depth. The nutrients level of soils in the sampling area showed the trends of shady slope > sunny slope, and surface soil > bottom soil. Compared to sunny slope, the cation exchange capacity (CEC), the contents of total organic carbon, total nitrogen, alkaline hydrolyzed nitrogen, available phosphorus, total potassium and available potassium of shady soils significantly increased by 43.7%, 103.8%, 92.0%, 75.5%, 22.4%, 89.4% and 240.7%, respectively. There was no significant difference in total phosphorus contents between shady slope and sunny slope. At all soil layers, there was no significant difference of C/N ratio between shady and sunny slopes. The average C/P ratio of shady slope was 180.8%, 42.0% and 54.3% higher than that of sunny slope at 0-20 cm, 20-40 cm and 40-60 cm, respectively. At each soil layer, the average C/K and N/K ratios between shady and sunny slopes had no significant difference. The average C/K and N/K ratios of shady slope and sunny slope were all significantly different among the three soil layers. In the shady slope, the contents of soil organic carbon showed significantly positive correlation with total nitrogen, total phosphorus, total potassium, and soil available nutrients. Overall, soil nutrients and ecological stoichiometry characteristics of shady slope of bamboo forest were superior to those of sunny slope.
