摘要:
为探究凋落物与土壤养分及土壤酶活性的地形差异,以及凋落物与土壤养分、土壤理化性质与土壤酶活性之间的相关关系,以贵州省茂兰喀斯特森林国家级自然保护区内的坡地、槽谷和漏斗3种典型地形为研究对象,对不同地形的凋落物和土壤碳(C)、氮(N)、磷(P)含量、化学计量比以及土壤酶活性等进行分析。结果表明:3种典型地形的森林凋落物总有机碳(TOC)含量、碳氮比(C/N)、碳磷比(C/P)、氮磷比(N/P)和土壤全氮(TN)、全磷(TP)含量、C/N、C/P、N/P均存在显著差异,地形显著影响凋落物和土壤养分含量及化学计量比。凋落物和土壤C、N、P含量及化学计量比间存在显著相关关系,凋落物TN含量与土壤TN含量、土壤N/P以及凋落物C/N与土壤N/P均呈显著负相关关系(P<0.05),凋落物TN含量与土壤C/N呈显著正相关关系。不同地形间土壤碱性磷酸酶、脲酶、蔗糖酶和过氧化氢酶的酶活性差异显著,且均为槽谷 > 漏斗 > 坡地,由于槽谷地形生境条件优越,水热、凋落物、土壤条件良好,土壤中植物根系发达,土壤微生物活动旺盛,因此表现出较高的酶活性。冗余分析表明,土壤酶活性主要受土壤TN含量、pH值、C/N、N/P的影响,TN含量为关键影响因子。
Abstract:
This study aimed to explore the differences in litter and soil nutrients, and soil enzyme activities among different terrains, as well as the correlation between litter and soil nutrients, soil physical and chemical properties, and soil enzyme activities. Three typical terrains, hillside, valley, and funnel, in Maolan Karst Forest National Nature Reserve, Guizhou, were selected as research areas. The C, N, and P content of litter and soil, the stoichiometric ratio, and soil enzyme activity in different terrains were analyzed. The results showed significant differences among the three typical terrains in the values of organic carbon, C/N, C/P, and N/P of forest litter and the total nitrogen(TN), total phosphorus, C/N, C/P, and N/P of soil; further, the terrain affected the litter-soil nutrient content and stoichiometric ratio significantly. There was a significant correlation between the C, N, and P content and the stoichiometric ratio of litter and those of soil. The litter TN and soil TN, the litter TN and soil N/P value, and the litter C/N value and soil N/P value, all showed a significant negative correlation(P<0.05). However, the litter TN and soil C/N value showed a significantly positive correlation. The activities of alkaline phosphatase, urease, sucrase, and catalase enzymes varied significantly among different terrains, and were all in the order valley > funnel > hillside. The high enzyme activity in the trough/valley might be a result of the superior habitat conditions, good conditions of water, heat, litter, and soil, the development of plant roots in soil, and strong soil microbial activity. Redundancy analysis showed that soil enzyme activity was mainly affected by soil TN, pH, C/N, N/P, and that TN was a key influencing factor.
