摘　　要：为研究西藏林芝巴结巨柏自然保护区开展旅游活动后巨柏的生长状况及游客行为,通过实地调查和问卷调查,首先对保护区内游客行为特征进行研究,发现其旅游活动相对集中于较短的时间范围和景区入口处,旅游活动单一。其次,由于保护区开展旅游活动已有较长的时间,结合游客的行为特征,对区内旅游干扰进行了调查。进行保护区土壤调查时将保护区划分为四个样区,并在每个区域内设置对照采样点,对保护区内不同样区的游道两侧不同距离的土壤硬度、含水率、容重及pH值进行了测定和分析,发现随旅游干扰强度的增加,土壤的物理、化学性质发生了相应的变化。同时,将保护区沿主要游道划分为三个样区,调查巨柏受伤害状况,发现游客活动频繁的区域,巨柏受伤害的可能性越大且受刻画等级越高。最后探讨了土壤理化性质、巨柏受伤害程度的变化趋势与旅游干扰强度关系。This paper studies tourists disturbance on Bajie Giant Cypress （ Cupressus gigantea Cheng et L. K. Fu ） Forest basing on a systemic analysis of previous work on relative subjects. Through on-site research, it seems that the tourists tend to gather around the entrance, and most tours are brief and monotonous, the level of tourist disturbance is found to be determined by sevral indexes including soil hardness, soil water content, soil unit weight, soil pH and the damage degree of tree trunks alongside trails. The result shows that the level of tourist disturbance increases with soil hardness, soil unit weight, soil pH and the damage of tree trunks, yet soil water content changes according to both tourist impact disturbance and the texture of dirt. Finally, the relationships among impacted soil, damaged tree trunks and the level of impact is also discussed.
