  • 摘要: 放牧是最主要的草地利用模式,直接或间接地影响草地物质循环和能量流动,放牧强度对草地的健康状况和演替方向起决定作用。本文基于40篇内蒙古草原放牧相关文献数据,通过meta分析探讨温带草原对放牧强度的响应特征。结果表明,与未放牧草地相比,轻度放牧草地对群落植物地上、地下生物量和土壤全氮和全磷含量无显著影响,而土壤有机碳、微生物生物量碳、细菌和真菌数量分别显著上升3.60%、7.80%、11.40%和10.83%(P < 0.05);中度放牧下群落植物地下生物量和土壤微生物数量无显著变化,而地上生物量和土壤有机碳、全氮、全磷和微生物生物量氮含量分别显著降低21.62%、4.44%、2.15%、8.35%和6.76%(P < 0.05);重度放牧下群落植物地上和地下生物量,土壤有机碳、全氮、全磷、微生物生物量碳含量,细菌和放线菌数量分别显著下降39.72%、16.30%、7.62%、6.46%、8.03%、8.76%、12.92%和18.27%(P < 0.05)。以上结果表明轻度放牧有利于土壤肥力和草地生产力的保持和提升,而当放牧干扰超出一定的限度时,草地各项功能均显著下降而发生退化。本研究可为内蒙古温带草原的合理利用和适应性管理提供理论基础。
