| 为研究近自然恢复模式下不同的立地条件和植物配置模式对播种植物增长率的影响,通过观测各种植被基部面积生长率、冠层面积生长率、基部体积生长率和冠层体积生长率等生长量指标,对比研究植物生长量增长率在不同立地条件和不同播种方式下的变化。结果表明：草坡立地下植被恢复的生长量增长率优于荒地,乔灌混播对比乔灌草混播差异不大,但优于乔木种子单播；主要出苗树种的生长量增长率在乔灌混播下更具有优势。结论：在近自然植被恢复中,良好的立地条件能获得较高植物增长率,乔灌混播模式对植物增长率更具优势,可为自然植被恢复模型提供生物量估算基础,对指导近自然植被恢复具有实际意义。 |

| Abstract: |
| In order to study the effects of different site conditions and plant configuration modes on the growth rate of sown plants under near natural recovery, the changes of plant growth rate were compared by observing the growth indicators such as basal area growth rate, canopy area growth rate, basal volume growth rate and canopy volume growth rate of various vegetation. The results showed that the growth rate of plants under grass slope vegetation restoration was better than that in wasteland. There was little difference between tree shrub mixed sowing and tree shrub grass mixed sowing, but better than tree seed single sowing; The analysis of the main seedling plants shows that the growth rate of the main seedling trees is more advantageous under the mixed planting of trees and shrub. |
