非木材森林产品利用的生态影响

Ecological effects of utilizing non-timber forest products.

非木材森林产品指来自森林的非木材植物产品,如果实、种子、枝叶、树皮、树胶等,在维持当地居民生活以及森林生物多样性保护中扮演着重要角色.非木材森林产品利用对植物个体、种群、群落和生态系统均会产生影响,这不仅取决于植物的利用部位、生物学或生态学特征,而且与资源的利用方式密切相关.本文从植物生物学和生态学角度综述了非木材森林产品利用影响的研究进展,讨论了研究中存在的问题和今后的研究方向.

Non-timber forest products（NTFPs） include all plant materials other than timber,such as seeds,flowers,fruits,leaves,roots,bark,latex,resins,and other non-wood plant parts.The significant role of NTFPs in improving local people＇s lives and forest biodiversity conservation has been widely accepted.However,many studies in past decades indicated that NTFPs utilization had various ecological effects on different levels,from plant individual and population to community and forest ecosystem,depending not only on the plant parts extracted and their biological or ecological attributes,but also on the harvest forms.This paper reviewed the research progress about the effects of the utilization of NTFPs from biological and ecological aspects,and discussed some research problems and research priorities.
