摘要/Abstract

摘要： 为探究放牧对陆地生态系统植物养分浓度和重吸收效率的影响,该文对21篇相关文献进行整合分析,探讨了放牧强度对植物氮（N）,磷（P）浓度及养分回收效率的影响,并进一步分析了环境因子和试验因素对其影响。结果表明：（1）放牧增加了陆地生态系统植物成熟器官N,P浓度和衰老器官N浓度,但对衰老器官P浓度无显著影响；（2）放牧增加植物N重吸收效率和P重吸收效率；（3）放牧对植物组织N、P和养分重吸收效率的影响大小和方向与放牧强度、生态系统类型、植物功能群和植物器官等因素有关。以上结果表明放牧显著影响植物氮磷养分浓度,增加植物氮磷的内循环。

关键词: 放牧, 氮磷浓度, 氮磷回收效率, 整合分析

Abstract: To investigate the effects of grazing on nitrogen （N） and phosphorus （P） concentrations and nutrient resorption efficiency of plants in grassland ecosystem,this study integrated and analyzed 21 relevant literatures toexplore the influence of grazing intensity on plant N,P concentrations,and nutrient resorption efficiency,and further analyzed the effects of environmental factors and experimental factors. The results indicate that：（1） Grazing increases N and P concentrations in mature organs of plants in terrestrial ecosystem and N concentrations in senescent organs,but has no significant effect on P concentrations in senescent organs；（2） Grazing reduces N resorption efficiency and P resorption efficiency of plants；（3） The magnitude and direction of the effects of grazing on plant tissue N,P,and nutrient resorption efficiency are related to grazing intensity,ecosystem type,plant functional groups,and plant organs. These results indicate that grazing significantly affects plant N and P nutrient concentrations by enhancing the internal cycling of N and P in plants.

Key words: Grazing, Nitrogen and phosphorus concentrations, Nitrogen and phosphorus resorption efficiency, Meta-analysis
