旅游干扰对明月山国家森林公园土壤的影响

Effect of Tourism Disturbance on Soil of Mingyue Mountain National Forest Park

本文在对土壤和植被调查的基础上,初步探讨了旅游干扰对明月山国家森林公园土壤的影响。研究结果表明,不同强度的人类旅游活动干扰,对土壤的影响不同。人类的旅游活动,破坏了表层土壤的大团聚体结构,对土壤pH值产生一定的影响。随着旅游干扰强度增大,土壤紧实度增加,土壤容重增大;孔隙度减少,水分含量减少,表现为旅游干扰核心区<缓冲区<背景区。有机质、碱解氮、速效态磷的含量在核心区、缓冲区和背景区之间差异不大。此外,人类活动对明月山国家森林公园土壤的影响具有一定的垂直空间分异性。不同坡位,人类对土壤的理化性质影响具有一定的差异。土壤水分、有机质和碱解氮含量均是下坡低于中坡和上坡,但pH和速效磷含量表现出下坡>中坡>上坡的趋势。

Based on the investigation of both soil and vegetation on the Mingyue Mountain, this paper studies preliminarily the effect to soil of tourism disturbance. The results indicate that the effect on the soil is different because of the different intensity human＇s tourism disturbance. The human＇s tourism destroys the structure of the big soil aggregates and effects to soil pH value. Following the intensity of the tourism disturbance enhancing, the soil＇s tightening increases, bulk density increases; porosity degree reduces, water content reduces, that showing core area 〈buffer area 〈background area. But the differences of the organic matter and alkaline nitrogen and effective phosphorus are not obvious in these three areas. In addition, the impact of human being activity over Mingyue Mountain has perpendicular differentiation. The soil water content and the organic matter and alkaline nitrogen are all lower seriatim downhill compared to both the slope and the uphill, while both the soil pH value and effective phosphorus reduces from downhill to uphill.
