旅游踩踏对大青沟自然保护区地表影响研究

Influence of the tourists' trampling on the surfaces of the National Daqinggou Natural Reserve

以现场调查及模拟试验结果为依据,研究了我国特有生境的内蒙古大青沟国家级自然保护区旅游踩踏活动对地表生态环境的影响。研究表明:旅游踩踏活动对地表破坏程度随游客体重、行进速度、地形坡度、地表疏松度等方面的增加而严重,下山方向行进和平行等高线方向行进对地表破坏程度大于上山方向行进,其中,地形坡度和行进速度是影响踩踏地表破坏程度的主要因子。为此提出,在该保护区,地表疏松陡坡地段要禁止游客行进,其它各地段游客要慢行。

The degree of the adverse effect of the tourists＇trampling on the surface of the National Daqinggou Natural Reserve in Inner Mongolia was researched in the paper for the first time. The research showed that the degree of the adverse effect of the tourists＂ trampling was related to the tourists＂ weight, walking speed, terrain, slope and porosity. Downward walking and contour parallel walking damaged the surface more seriously than upward walking did. The grade of the slope and the walking speed played a key role in damaging the land surface. It is suggested that the tourists should be forbidden to walk on the steep and loose slopes. Slow walk is suggested in the whole reserve.
