摘 要:昭通市草地以山地草甸为主,草地生态系统脆弱,管理水平和建设能力不高,退化草地修复难度大。昭通市现有草地面积116079.33 hm^(2),其中退化草地面积6992.10 hm^(2),占全市草地总面积的6.02%。退化草地主要以轻度退化为主,面积4221.00 hm^(2)。草地退化的原因包括人为因素、有害生物侵入、生态环境脆弱和气候因素。文章给出近自然修复、人工促进修复、人工草地建植和综合修复等退化草地修复措施,并提出加快草种基地建设、规范草地管理、生态优先、因地制宜等草地修复策略。The grasslands in Zhaotong City are mainly mountainous meadows,with fragile grassland ecosystems and low management and construction capabilities,making it difficult to restore degraded grasslands.The current grassland area in Zhaotong City is 116079.33 hm^(2),of which 6992.10 hm^(2)was degraded grassland,accounting for 6.02%of the total grassland area.The degraded grassland is mainly characterized by mild degradation,with an area of 4221.00 hm^(2).The reasons for grassland degradation include human factors,invasion of harmful organisms,fragile ecological environment,and climate factors.This paper provided measures for the restoration of degraded grasslands,including near natural restoration,artificial promotion restoration,artificial grassland planting,and comprehensive restoration,and suggested to accelerate the construction of grass seed bases,standardize grassland management,prioritize ecology,and adapt to local conditions.
