摘要
草原是我国重要的生态系统和自然资源,在维护国家生态安全、边疆稳定、民族团结和促进社会经济可持续发展、农牧民增收等方面都具有基础性、战略性作用。当前草原生态脆弱的形势依然严峻,仍然有70%的草原处于不同程度的退化状态,草原保护修复任务还十分艰巨。文章结合生产实际,从土壤侵蚀治理、恢复植被覆盖率和土壤肥力、增加草地植物种类和生物多样性、提高草地生态系统自我维持能力、控制草地人为干扰等方面介绍天然草地修复技术,以期为生产实践提供科学依据和参考。
Grassland is an important ecological system and natural resources in China,which plays a basic and strategic role in maintaining national ecological security,border stability,national unity,promoting social and economic sustainable development,and increasing the income of farmers and herdsmen.At present,the ecological fragility of the grassland is still severe,and 70%of the grassland is still in varying degrees of degradation,and the task of grassland protection and restoration is still very arduous.Based on the production practice,the natural grassland restoration technology was introduced from the aspects of soil erosion control,restoration of vegetation coverage and soil fertility,increase of plant species and biodiversity,improvement of self-sustaining ability of grassland ecosystem,and control of artificial disturbance of grassland,so as to provide scientific basis and reference for production practice.
