二龙山水库控制流域刺五加生态分布与开发对策

ECOLOGICAL DISTRIBUTION AND DEVELOPING STRATEGY OF ACANPHOPANAX SENTICOSUS IN THE DRAINAGE BASIN OF MOUNT ER-LONG RESERVOIR

对二龙山水库控制流域刺五加的调查与研究结果表明，刺五加的分布与环境质量成正相关．在极度退化区的生态系列中没有分布．在该地区保护和恢复刺五加资源应以刺五加的生理生态特征为基础，以移植刺五加为主要手段，以人工收集种子，促进种子繁殖为重要补充手段，来实现次生林和人工落叶松林下环境的合理配置与发展．

The results of investigation and research on Acanphopanax senticosus in the drai nage basin of Mount Er-Long reservoir show that the distribution range of Acan ph opanax senticosus positively correlates with environmental quality,which disap pe ars in the ecological series of extreme degenerative regions.As a result,in orde r to realize reasonable allocation and development of Acanphopanax senticosus resources under secondary forest and larch plantation in the area,we must protect a nd recover Acanphopanax senticosus resources by the main means of transplant atio n and the important supplementary way of artificially collecting seeds and facil itating seed propagation on the basis of its physiological ecological traits.
