| 摘 要： | 川中丘陵为长江中上游防护林体系建设重点区域。本文对荒山荒坡种植柏木、桤木及补播牧草后的植被动态进行了研究。结果表明：在幼林期，随树木郁闭度的增加，林下草本植物的盖度也随之提高，生物量增大，林草之间具良好的共生效益；补播草种可大大加快幼林地植被覆盖。

| Abstract: | The hilly area in the central part of the Sichuan province is one of the most important region for construction of the protective forest systems in the upper and middle reaches of the Yangtze River.The vegetation dynamics of a young Alnus cremastogync and Cuprcssus funebris woodland with sown her- bage on the bare hills in the region was investigated.The results showed that the coverage and biomass of the understorey herbage communities increased simultaneously with the growth of the young trees.The restoration of the ve- getation in the hilly area could be accelerated by planting trees together with sowing herbage. |
