This study investigated a 38-year-old enclosed grassland in Yunwu Mountain, Ningxia, by systematically analyzing ecological-metabolic ratios and their coupling relationships at the community level (community-weighted average) for leaves and soil across four grazing intensities of Gansu Cervus canadensis (Cervus elaphus kansuensis): ungrazed, light grazing, moderate grazing, and heavy grazing. Results indicated: (1) Moderate grazing most effectively promoted N and P accumulation. Plant growth shifted from P limitation under no grazing and combined N-P limitation under light/moderate grazing to N limitation under heavy grazing; (2) With increasing grazing intensity, both topsoil soil organic carbon (SOC) and C∶N ratio in the topsoil (0~10 cm) showed an initial increase followed by a decrease, peaking at moderate grazing levels at 40.40 g·kg-1 and 12.08, respectively. Conversely, soil N, C∶P, and N∶P ratios were the lowest at light grazing levels at 3.22 g·kg-1, 48.15, and 4.43, respectively. All soil parameters decreased with increasing soil depth. (3) Leaf C and N contents showed negative correlations with most soil SOC, N, P, and their ratios, while leaf P content was correlated positively with these parameters. Soil depth influenced both plant leaf and soil chemical parameters, whereas grazing intensity primarily affected soil-related indicators. In summary, grazing significantly influenced the chemical-nutrient characteristics of the plant-soil system in the long-term enclosed grassland of Yunwu Mountain. Moderate grazing promoted plant growth and soil nutrient accumulation, representing a critical grazing intensity threshold for maintaining regional grassland health. These findings provide data support and theoretical basis for further optimizing grazing management and promoting the sustainable use of long-term closed-pasture grasslands., authors=MA Xiao-rui1, LI

articleAbstract=探讨放牧对长期封育草地植物-土壤连续体碳(C)、氮(N)、磷(P)生态化学计量学特征的影响对草地可持续管理具有重要意义。本研究以宁夏云雾山封育38年的草地为研究对象,通过设置未放牧、轻度放牧、中度放牧、重度放牧4种甘肃马鹿(Cervus elaphus kansuensis)放牧强度,系统分析群落水平(即群落加权平均)叶片和土壤的生态化学计量比及其耦合关系。结果表明:(1)中度放牧最有利于N, P养分的积累,且植物生长的养分限制由未放牧的P限制和轻、中度放牧的N-P共同限制,转变为重度放牧的N限制;(2)随放牧强度的增加,表层(0~10 cm)土壤有机碳(Soil organic carbon,SOC)、C∶N均呈先升后降的趋势,并在中度放牧达峰值,分别为40.40 g·kg⁻¹,12.08,而土壤N, C∶P, N∶P则在轻度放牧最低,分别为3.22 g·kg⁻¹, 48.15, 4.43,随土层加深,所有土壤指标均呈递减趋势;(3)叶片C, N含量与多数土壤SOC, N, P及计量比呈负相关,而叶片P含量与这些指标则呈正相关;土层深度同时影响植物叶片和土壤化学计量,而放牧强度则主要作用于土壤相关指标。综上,马鹿放牧显著影响了云雾山长期封育草地植物-土壤系统的生态化学计量特征,中度放牧有利于植物生长和土壤养分积累,是维持区域草地健康的关键放牧强度阈值,这些结果为进一步优化放牧管理,促进长期封育草地的可持续利用提供了数据支撑和理论依据。, authors=马晓瑞1,

Investigating the effects of grazing on the ecological chemometric characteristics of carbon (C), nitrogen (N), and phosphorus (P) in the plant-soil continuum of long-term enclosed grasslands is crucial for sustainable grassland management. This study investigated a 38-year-old enclosed grassland in Yunwu Mountain, Ningxia, by systematically analyzing ecological-metabolic ratios and their coupling relationships at the community level (community-weighted average) for leaves and soil across four grazing intensities of Gansu Cervus canadensis (Cervus elaphus kansuensis): ungrazed, light grazing, moderate grazing, and heavy grazing. Results indicated: (1) Moderate grazing most effectively promoted N and P accumulation. Plant growth shifted from P limitation under no grazing and combined N-P limitation under light/moderate grazing to N limitation under heavy grazing; (2) With increasing grazing intensity, both topsoil soil organic carbon (SOC) and C∶N ratio in the topsoil (0~10 cm) showed an initial increase followed by a decrease, peaking at moderate grazing levels at 40.40 g·kg-1 and 12.08, respectively. Conversely, soil N, C∶P, and N∶P ratios were the lowest at light grazing levels at 3.22 g·kg-1, 48.15, and 4.43, respectively. All soil parameters decreased with increasing soil depth. (3) Leaf C and N contents showed negative correlations with most soil SOC, N, P, and their ratios, while leaf P content was correlated positively with these parameters. Soil depth influenced both plant leaf and soil chemical parameters, whereas grazing intensity primarily affected soil-related indicators. In summary, grazing significantly influenced the chemical-nutrient characteristics of the plant-soil system in the long-term enclosed grassland of Yunwu Mountain. Moderate grazing promoted plant growth and soil nutrient accumulation, representing a critical grazing intensity threshold for maintaining regional grassland health. These findings provide data support and theoretical basis for further optimizing grazing management and promoting the sustainable use of long-term closed-pasture grasslands.
