【摘要】 生态系统服务功能已成为生态学及相关领域关注的焦点,人类渴望高效优质的生态系统服务功能。由于种种原因形成了大量的不符合人们经营要求的低价林,它们的生态系统服务功能低下,在很大程度上影响和制约着我国林业乃至社会与经济的可持续发展,低价林问题已引起了人们的普遍关注。目前在学术研究领域和生产实践中,关于低价林方面的称法或概念很多,很不规范、不统一,这也在一定程度上造成了当前低价林的相关研究和实践中较混乱的局面,也严重影响了相关方面的学术交流等活动。针对低价林领域概念比较混乱、不规范、不统一的现状,从森林经营目标的角度定义了低价林概念:把那些由于种种原因引起的没有达到主要经营目标的林分统称为低价林。参照我国林种的划分给出了低价林分类系统;低价林的命名应遵循“(优势)树种-低价-林种”方法。更多还原

【Abstract】 The ecosystem service is the focus in the field of ecology. People look for high-effect and high-quality ecosystem service. However, for many reasons there are a large number of low-value forest which is not satis-fiable to people’ s management demand. The service of the low value forest restricts the sustainable development of forestry, society and economy, which has caused wide attention. In this paper we defined the concept of low-value forest in view of forest management target. We also make the classification system of low-value forest according to forest classes system in China. The name of low-value forest should follow the rule of "(predominant) tree species + low-value + forest class".更多还原
