摘要:
在科尔沁沙地南缘，以严重沙化草地作为研究对象，通过布设人工补播试验，以及对飞播9 a后沙化草地各植被群落特征的调查，研究了补播改良措施对沙化草地植被恢复的作用。结果表明：飞播措施和人工补播措施对沙化草地植被恢复均具有显著作用。飞播9 a后的沙化草地，植被盖度、草群平均高度、草群密度以及地上生物量分别较对照样地提高了2.71倍、1.91倍、1.54倍和3.85倍。人工补播措施对改善沙化草地群落特征具有持久性，其中条播方式优于穴播和撒播方式。
Abstract:
In the south edge of Horqin sandy land, taking serious desertification grassland as subject, the effects of reseeding on vegetation restoration in desertification grassland are researched by designing artificial reseeding tests and investigating the vegetation characteristics in desertification grassland which adopted the measures of airplane seed sowing in last 9 years. The results show that the measures of airplane seed sowing and artificial reseeding all have significant function. The coverage, mean height, branch number and aerial part biomass in desertification grassland which adopted the measures of airplane seed sowing in last 9 years increased 2.71 times, 1.91 times, 1.54 times and 3.85 times more than the control plot. The measures of airplane seed sowing has a long-term improvement effect on the vegetation characteristics of the desertification grassland. And the effect of artificial line seeding is better than dibble seeding and broadcast.
