摘要
对生态公益林林下植物的影响进行了综述,包括间伐强度及间伐对林下植物种类、多样性和植被生物量的影响。表述结果为:间伐后林下耐荫植物衰退,喜光植物增多;中强度间伐的林下植被生长最好,多样性指数最高;间伐一般能增加林下植被生物量。今后需要研究间伐对林下植被的生物多样性的长期影响。
This paper summarized The effects of thinning on undergrowth in ecological forests were summarized, including thinning in- tensity and thinning effects on species, diversity and biomass for undergrowth. The results showed that： Shade-tolerance plants de- crease, whereas sun plants increase after thinning. Undergrowth growth and indices of plant diversity index are greatest under the medi- um thinning. Undergrowth biomass generally increases after thinning. In the future, study on the long-term effects of thinning on the di- versity of undergrowth is necessary to promote the sustainable development of ecological forests.
