摘　　要： 随着生态旅游的兴起,生态旅游目的地的环境问题也日益显现。以广东省南昆山自然保护区的上坪—中坪旅游活动景区为例,选取了景区内观音潭和三仙溪鸣两个停车场以及9个有代表性的游径横断面,利用采集土壤样品、对土壤理化性质进行测定的方法,对土壤样品的土壤有机质、有效氮含量、pH值和土壤质地进行对比分析,探讨了旅游践踏强度与土壤理化性质变化之间的关系。 Along with studies about tourist＇ impacts on the environments developed quickly, methods of documentation and case study were employed. The compositions and pH values of soil were analyzed, contents of organic matter and available nitrogen decrease were also examined. An demonstration studies was made to classify the degree of the soil impacts on the soil-environment. At last, this paper discussed the interrelation between the soil characters changing with the different intension of the tourist＇s trample on the pathway.
