人工林在生物多样性保护中的作用

Discussion on Effects of Plantation on Biodiversity Conservation

综述了近年来世界人工林的发展动态以及人工林在生物多样性保护方面的最新研究进展;从人工林与乡土森林的比较中,表明了多数情况下人工林支持的物种多样性并不少于乡土森林植被,同时表明了人工林已经成为一些稀有、濒危物种的重要庇护所和替代生境,在很大程度上支持了人工林并不是生物多样性“沙漠”的观点;分析了影响人工林生物多样性的因素及保护人工林生物多样性的途径。

Dynamics of plantation worldwide and recent research on the effects of plantation on biodiversity conservation were summarized. Compared with native natural forests, plantation can contain as many biodiversity as native natural forests in many conditions. And some rare, threatened ,indigenous species sometimes occurred in plantation that they used as substitutive habitats and important shelter. These results, to a great extent, support the conclusion that plantation was not the ＂desert＂ of biodiversity. Influential factors of plantation on biodiversity were analyzed and the enhanced approaches of biodiversity in plantation were recommended.
