【摘要】 [目的]通过对土壤理化性质、肥力指标及特征进行分析,探讨旅游对自然保护区的影响。[方法]采取的方法是样带法。[结果]由于旅游干扰,人为践踏使地表枯落物减少1/2,有机质含量平均下降7%,土壤全氮含量平均减少0.04 g/kg,其余全磷等都不同程度有所下降。[结论]随着人为干扰强度的增大,土壤肥力状况呈下降趋势,并且这种趋势在0～20 cm土层表现的比较明显。更多还原

【Abstract】 [Objective] The purpose of the study was to explore the impacts of the tourism on nature reserves by exterminating the soil physical and chemical properties,fertility indicators and analyzing those characteristics.[Method] The belt transects method was adopted.[Result] The amount of surface litter was reduced 1/2,organic matter content was reduced 7%,the soil total nitrogen content was reduced 0.04 g/kg,and the contents of the other matters such as soil total phosphorus content were all reduced in various degree by human trampling and tourism disturbance.[Conclusion] The soil fertility showed a decrease trend with the increasing intensity of human disturbance,obviously in 0-20 cm soil layer.更多还原
