海南热带雨林原生植被与槟榔树种植的固坡阻滑效果对比研究

通过实地考察和调研海南热带雨林原生植被以及槟榔树种植基地发现:在原有热带雨林山坡地上改种经济作物槟榔树之后,滑坡发生的规模及频率在近几年显著增加,造成严重的生态破坏,不利于热带森林公园旅游资源的开发与利用.为此,本研究对比分析了热带雨林原生植被和经济作物槟榔树在林冠层、树干以及地表落叶、植株密度和根系分布等在生态固土护坡方面的差异,简要阐述了槟榔树种植基地频繁发生滑坡的原因.

Comparation of the Anti-sliding Effects between Hainan Tropical Rain Forest Vegetation and Betel Nut Trees

In our study,the field investigation of Hainan tropical rainforest native vegetation and betel nut tree planting base was performed.The results indicated that after planting betel nut trees on the original tropical rain forest hill,the scale and frequency of the landslide increased significantly,which caused serious ecological damage,and was not benificial for the development and utilization of tropical forest park tourism resources.Comparation of the anti-sliding effects between Hainan tropical rain forest vegetation and betel nut trees,which include the forest canopy,tree trunks,leaves,plant density,root distribution,and surface features,and the reasons of landslide of the betel nut tree planting base were elucidated.
