缙云山游客活动区黄壤的理化性质研究

在野外调查和室内分析的基础上,研究了缙云山国家级自然保护区游客主要活动区黄壤的理化性质状况.结果表明,游客对景色区的践踏、废弃物的随意丢弃会对土壤造成明显冲击.土壤容重、土壤含水量、土壤有机质含量与践踏程度呈极显著相关.土壤氮、磷、钾含量差异较大,其中,氮、钾水平较高,磷水平较低.全氮、有效氮含量与践踏程度极显著相关,磷、钾受游憩活动冲击影响较复杂.

Studies on Physical and Chemical Properties of Yellow Soil Effected by Tourist Activities in Jinyunshan Mountain

The results from field investigation and lab sample analysis indicated that the impacts of tourist activities as trampling of scene district and throwing away the rejectamenta on yellow soil were significantly.Within the area,where affected by tourist activities,the soil bulk density,soil moisture and the soil organic matter content were all greatly significantly correlated with the trampling intensity.The content of soil nitrogen,phosphorus and potassium were obviously different,in which,the nitrogen and soil potassium had a high level,but the phosphorus had a low level.The correlation between the content of whole nitrogen and available phosphorus and trampling intensity reached a greatly obvious level.The effect of trampling intensity on soil phosphorus and potassium was complicate because of impacts of tourist activities.
