旅游干扰对祁连山风景区土壤性质的影响
Effects of Tourism Disturbance on Soil Properties of Qilian Mountains Scenery District
摘要
Abstract
This study explored the effects of tourism disturbance on soil properties in Qilian Mountains Dayekou scenic spot. The results indicated that the tourists concentrated from May to August, most of them choose self-driving way and picnic and barbecue. Tourist activity had greater influences on soil pH, bulk density, moisture and organic matter of surface soil in the tourist core area. With the decrease of tourism disturbance, pH of surface soil increased gradually, but pH of 10–20 cm soil layer changed little. Soil bulk density was in an order of Core area > Buffer area > Background, soil moisture in an order of Background > Buffer area > Core area. Tourist activities had great influence on soil organic matter content in the core area and buffer area, which significantly lower than background area by 63.6% and 60.1%, respectively. Total nitrogen, total phosphorus and total potassium of surface soil were in order of Background > Buffer area > Core area, while these contents of 10–20 cm soil layer showed little difference. Soil available nutrients in 0–10 cm soil layer were higher than in 10–20 cm soil layer. The available nitrogen and phosphorus in 0–10 cm soil layer were higher, available phosphorus in 10–20 cm soil layer was higher. All available trace elements were higher in 0–10 cm soil layer than in 10–20 cm soil layer, and were highest in core area.关键词
