游客踩踏对植被和土壤影响研究进展

Research Progress on the Effects of Tourist Trampling on Vegetation and Soil

随着旅游业的发展,随之带来的生态环境问题日益突出,很多学者研究探讨关于踩踏干扰对植被和土壤的影响。通过查阅相关文献和研究资料、整理与归纳,综述了踩踏干扰对植物和土壤的影响,包括群落外观及物种组成、物种多样性、群落根系与土壤容重、孔隙度和土壤养分等研究进展。游客踩踏导致植物多样性、高度和盖度降低,对土壤动物和微生物造成影响;踩踏干扰致使土壤容重增加,孔隙度减少,土壤养分含量下降。最后对全文进行总结和展望,提出未来研究方向需在原有基础上深入探讨踩踏对草地群落的影响,同时注重生态环境保护和景区合理规划。

With the development of tourism,the ecological and environmental problems have become increasingly prominent.Many scholars have studied the impact of stampede on vegetation and soil.In this paper,the effects of trampling on plants and soil were reviewed b y consulting relevant literature and research data,sorting and summarizing,including community appearance and species composition,species diversity,community roots and soil bulk density,porosity and soil nutrients.Tourist trampling leads to a decrease in plant diversity,height and coverage,which affects soil animals and microorganisms.Trampling disturbance increased soil bulk density,decreased porosity and soil nutrient content.Finally,the full text is summarized and prospected.It is proposed that the future research direction should be based on the original basis to explore the impact of trampling on grassland communities,and pay attention to ecological environment protection and reasonable planning of scenic spots.
