摘要
长期以来,云南松的纯林经营使得生物多样性降低、林分稳定性变差、遗传品质退化、林分生产力下降,从而导致生态系统功能衰退。针对这些实际情况,本文依据国内外研究成果对云南松纯林近自然化改造的技术和理论进行了探讨,为恢复云南松群落的生态功能和经济功能提供依据。
The long-term pure forests of Pinus yunnanensis management lead to bio-diversity decrease, diseases and insect pests damage, genetic degradation, and productivity decline. According to the domestic and overseas experience, the technology and theory of approaching-nature forest management of the pure forests are discussed in the paper, to provide gist for restoring the ecological function and economic benefit of the community.
