摘要/Abstract

摘要： 以长白山区天然泥炭地、不同水文管理的恢复泥炭地（高水位、高-低水位循环和低水位）及退化泥炭地（弃耕地）为研究对象，分析水文管理措施对恢复泥炭地表层土壤（0～10 cm）酶活性的影响及其驱动因素。结果表明：泥炭地土壤β-1,4-葡萄糖苷酶和β-1,4-N-乙酰葡糖氨糖苷酶活性表现为天然泥炭地>恢复泥炭地>退化泥炭地；退化泥炭地土壤酸性磷酸酶活性显著低于天然泥炭地和恢复泥炭地；多酚氧化酶活性在天然泥炭地最低。在恢复泥炭地，随着恢复区管理水位的下降，土壤β-1,4-葡萄糖苷酶、β-1,4-N-乙酰葡糖氨糖苷酶和酸性磷酸酶活性均逐渐降低，土壤多酚氧化酶活性表现为高低水位循环恢复区最低。相关分析表明，土壤β-1,4-葡萄糖苷酶活性和β-1,4-N-乙酰葡糖氨糖苷酶活性均与土壤有机碳、含水量、水位和全氮含量呈显著正相关，与pH和全磷含量呈显著负相关；土壤酸性磷酸酶活性与水位呈显著正相关，与pH和全磷含量呈显著负相关；土壤多酚氧化酶活性与土壤有机碳、含水量和全氮含量呈显著负相关。RDA分析表明，环境因子共可解释研究区土壤酶活性变异的81.2%，水位和土壤有机碳是影响研究区土壤酶活性的主控因子。适宜的水文管理措施能有效提高退化泥炭地土壤有机碳、氮等养分元素含量及土壤微生物酶活性，提升土壤的生态功能，加速生态系统功能的恢复。

Abstract: We analyzed the effects of hydrological management measures on soil enzyme activities (0-10 cm) and their driving factors during peatland restoration across natural peatland, restored peatland under different hydrological managements (high water level, alternating high-low water level, and low water level) and the degenerated peatland (abandoned land) in Changbai Mountains. The results showed that the activities of β-1,4-glucosidase and β-1,4-N-acetyl-glucosaminidase decreased from natural peatlands to restored peatlands to degraded peatlands. The activity of acid phosphatase in degraded peatlands was significantly lower than that in natural and restored peatlands, while the activity of polyphenol oxidase was the lowest in natural peatlands. In the restored peatlands, the activities of soil β-1,4-glucosidase, β-1,4-N-acetyl-glucosaminidase and acid phosphatase decreased gradually with the decreasing water level. However, the activity of soil polyphenol oxidase was the lowest in the restored peatlands under the hydrological management with alternating high-low water level. The activities of β-1,4-glucosidase andβ-1,4-N-acetylglucosaminidase were positively correlated with soil organic carbon content, water content, water level and total nitrogen content, and negatively correlated with pH and total phosphorus content. Soil acid phosphatase activity was positively correlated with soil water level, and negatively correlated with pH and total phosphorus content. Soil polyphenol oxidase activity was negatively correlated with soil organic carbon content, water content and total nitrogen content. Results of redundancy analysis showed that environmental factors explained 81.2% of the total variation in soil enzyme activities. Water level and soil organic carbon content were the main factors controlling soil enzyme activities. Our results indicate that appropriate hydrological management can effectively improve the contents of soil organic carbon, nitrogen and other nutrient elements and soil microbial enzyme activities of thedegraded peatlands, enhance soil ecological function, and accelerate the recovery of ecosystem function in peatlands.
