自然保护区旅游活动对土壤性质影响的研究——以缙云山为例

研究重庆市缙云山国家级自然保护区新兴的旅游活动--农家乐对土壤理化性质的影响,采取农家乐附近土样,测定其pH值、含水量、体积质量、有机碳、有机氮和全氮.结果表明,由于受到旅游活动的影响,土壤的pH值有上升的趋势,土壤表层和深层含水量变化和体积质量变化有很大差异,有机质含量因人类活动类型的不同而产生上升和下降两个不同方向的变化.总之,旅游活动对土壤性质产生了显著的影响.土壤是自然环境中一个易受破环却很难治理和恢复的因素,因此,必须重视环境保护和旅游发展相协调.

Study on Impacts of Tourist Activities on Soil Properties in National Nature Reserves:A Case Study in Jinyun Mountain

Soil Physical and Chemical Properties that newly emerging tourist activities-Nongjiale impact on in Jinyun Mountain National Nature Reserve,were analyzed.The authors tested the pH,moisture,bulk density,organic carbon,organic matter and Total nitrogen of soil samples.The results show that because of the tourist activities,the pH tends to be higher.Moisture of surface layer and deep layer and bulk density of soil samples are significantly different.Organic matter content tends to be higher or lower due to different types of human activities.No matter what tourist activities indeed cause significantly impacts.Soil is one of the sensitive and vulnerable natural factors,so coordinating the relationship between environmental protection and tourism development is very important.
