Response of Soil Ecological Environment to Tourist Disturbance in Lijiang Scenic Area
[Objective] The response of soil ecological environment to interference by tourism was explored in Lijiang scenic area of Guilin City in Guangxi Zhuang Autonomous Region to provide a scientific basis for the rational development and protection of tourism resources.[Methods] A field investigation and laboratory analysis were conducted to analyze the differences of soil environmental indicators in the Lijiang scenic area under different interference levels
and the impact of interference due to tourism on the soil ecological environment in the study area.[Results] The average soil firmness increased by a factor of 15.55. The brightness and chromaticity of the soil color also increased
as did the bulk density (by 33.43%). The thickness of the litter layer and soil moisture content both decreased. The contents of soil organic matter
total nitrogen
alkali-hydrolyzed nitrogen
available phosphorus
and available potassium decreased by 61.31%
61.58%
32.21%
72.08%
and 36.26%
respectively.[Conclusion] The soil ecological environment of the Lijiang scenic area shifted periodically under the disturbance caused by tourism. Selected soils were degraded to different degrees
the comprehensive fertility of the soil reduced
and the soil structure deteriorated
which can be expected to affect vegetation and the landscape. Therefore
effective management measures and relevant technology should be introduced to weaken the negative effects of tourism on the ecological environment of the Lijiang scenic area.
