摘要 通过对卧龙保护区人工林和次生林的长期监测对比,结果表明:人工林树高、胸径的生长速度高于次生林;人工林的灌木层和草本层盖度以及植物种数均小于次生林;人工林土壤腐殖来源单一,其厚度也小于次生林;退耕还林由于土壤肥力高,林木生长迅速,郁闭度高,林下植物种类更少于其他人工林;人工林树种单一,病虫害多发,野生动物痕迹稀少,其森林健康度小于次生林。人工林下很少保存有大熊猫等野生动物生存所必须的竹子、灌丛和草本植物等食物资源,对大熊猫等野生动物具有排斥效应。大熊猫栖息地恢复重建应采取自然恢复方式,使用本地乡土树种,建设有卧龙地方特色的大熊猫栖息环境。 Through long-term monitoring and comparison of plantation and secondary forests in Wolong Nature Reserve, the results showed that the growth rate of tree height and DBH of plantation was higher than that of secondary forest;the shrub layer and herb layer coverage and plant species of plantation were lower than that of secondary forest;the source of colonization is single, and its thickness is also smaller than that of secondary forest. Because of high soil fertility, forest growth is rapid, and canopy is high, and understory plant species of conversion of cropland to forest land are less than other plantations;the plantation forest is single in species, with many diseases and insect pests and few wildlife traces, and its forest health is less than that of secondary forest. Plant resources such as bamboo, shrubs and herbs necessary for the survival of wild animals such as giant pandas are rarely preserved under plantations, and have a repulsive effect on wild animals such as giant pandas. It is necessary to adhere to measures for the natural restoration of the panda habitats, using local native tree species, and building the panda habitat with Wolong local characteristics.
