摘  要:
分析了位于云南省西北部的香格里拉县纳帕海湿地无序旅游活动对湿地土壤环境造成的影响,结果表明:随着旅游活动强度的增大,土壤的物理和化学性质发生了明显的变化,主要表现在土壤容重增大,总孔隙度降低,含水率降低,渗透性变差,土壤pH值升高,有机质含量、全氮含量和C/N比值均有所降低,土壤质地变差,并且导致了植被覆盖率和多样性的降低,湿地生态环境处于恶性循环当中,湿地土壤退化严重。

摘  要:
The Impacts of unorderly tourist activities on the environment in Napahai wetland scenic spot in Shangri-La county in the west of Yunnan province were studied.The results showed that as the strength of tourist activities increased,the soil characters of both physical and chemical were obviously changed.It was mainly acted that the soil density was increased,the degree of soil total hole was decreased and also the degree of soil water was brought down.The soil osmosis became bad.At the same time,the PH of soil was increased.The ratio of the C/N in the soil,the quantity of the organic matter and the total nitrogen were decreased.The qualities of the soil had become worse.The population and the covering degree of plant were also decreased.The wetland ecology environment was malignantly circling and the wetland soil was seriously degenerated.
