【摘要】 围栏封育是退化草地恢复的重要措施，对于维持草地生产力和生态系统平衡具有不容忽视的重要意义。总结围栏封育与草地植被和土壤的相互关系以及围封条件下不同类型草地植被生长和土壤特性的变化特征，指出因围栏封育下放牧牲畜的干扰消失，草地植物多样性、生物量及其分配格局、土壤理化性质以及养分有效性等易产生差异性响应，围封年限、草地类型、土壤特性和气候环境等是影响草地生产力、植被群落演替和生态系统服务功能的重要因素。更多还原

【Abstract】 Enclosure is an important measure for the restoration of degraded grassland, and it is of great significance to maintain the balance between grassland productivity and ecosystem development. This study thoroughly analyzed the relationship between enclosure and grassland vegetation and soil, as well as the change in vegetation growth and soil characteristics of different types of grassland under enclosure conditions. It was pointed out that the disturbance of grazing livestock disappeared under enclosure, and the diversity of grassland plant, biomass and its distribution pattern, soil physicochemical properties and nutrient availability were easy to produce differential responses. Factors such as enclosure years, grassland types, soil properties and climatic conditions were considered to complicatedly affect grassland productivity, vegetation community succession and ecosystem service function changes.更多还原
