| 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.

| Abstract: | This paper summarized The effects of thinning on undergrowth in ecological forests were summarized,including thinning intensity and thinning effects on species,diversity and biomass for undergrowth.The results showed that: Shade-tolerance plants decrease,whereas sun plants increase after thinning.Undergrowth growth and indices of plant diversity index are greatest under the medium thinning.Undergrowth biomass generally increases after thinning.In the future,study on the long-term effects of thinning on the ... |
