| 摘 要： | 补播是退化天然草植被恢复过程中的主要措施,种子萌发与种苗存活是植物生活史的关键时期,它可以潜在的影响到植物种群的结构和群落的组成,影响种子萌发和种苗存活的因素不同,所以有必要了解影响这两个过程的因素,提高种子的萌发率和种苗的存活率,加速植被恢复进程.

| Abstract: | Reseeding is a major measure in the recruitment of vegetation.Seed germination and seedling emergence are critical stages in the life history of plants,and have potential to influence population structure and community composition.Factors affecting these two processes are different,it is necessary to know these factors,so that to improve the rate of seed germination and seedling survival and enhance vegetation restoration. |
