旅游开发对景观边缘植物溢出效应的影响
Effects of tourism development on plant spillover effects at the edge of a landscape
摘要
Abstract
Anthropogenic landscape alteration can create fragmented habitats and alter edge structures,considerably affecting the natural dispersal of plant species.In this study,we conducted a comparative analysis on edge-spillover effects of animal-dispersed,wind-dispersed,unassisted-dispersal (including species dispersed by gravity and ejection),and total species between both recreational/non-recreational zones,and traffic/non-traffic corridors in the Khanka nature reserve based on the plant individual motion ecology—seed dispersal modes.The results showed that edge-spillover effects of both animal-dispersed and total species were significantly weaker in recreational zones than in non-recreational zones,while wind-dispersed species significantly spilled over in both zones.We only documented a few unassisted-dispersal species spilling over in either zone.The spillover-effects of animal-dispersed species were weaker in traffic corridors than in non-traffic corridors;in contrast,the spillover effects of wind-dispersed species in traffic corridors were significantly stronger than in non-traffic corridors.Similar to the recreational and non-recreational zones,a few unassisted-dispersal species spilled over into both experimental corridors and their spillover distances were relatively shorter than that of the animal-dispersed and wind-dispersed species.There was no significant difference in the total species spillover effects between the two types of corridors.The results indicated that tourism development had a considerable effect on the motion ecology of plants,leading to changes in spillover effects.关键词
