The Effects of Tourism Interference on the Soil of Grassland Tourist Spots-A Study of Gold Saddle Tourist Spots of Xilamuren Grassland in Inner Mongolia

摘要

Soil was sampled according to the distance surrounding different activities area and on different levels of travel channel around the gold saddle tourist spots of Xilamuren grassland in Inner Mongolia. Soil samples were collected every 5 cm until down to 30 cm in each plot with soil wreath knife. Analyze soil compaction, bulk density, soil moisture content, pH, soil organic matter, available P, total N, total P and total K by experiment. Through data analysis, study the response of tourism interference on soil physical and chemical properties. Study shows that the destruction of tourism activities on the grassland soil is big and the intensity of tourism activities are positively correlated to the degree of interference. The nearer to the concentrated region of tourism spots facilities, the greater intensity of tourist disturbance and the greater damage of soil. The damage of soil in south side was significantly greater than that in the north side. Travel interference changes differently in different tourism activity area. The damage extent of interference in obo district and book field was greater than that on both sides of horse tract. Different levels of travel channel showed that interference degree was different by the frequency size of vehicle rolling and the destruction of soil conditions was consistent with it. Tourism interference is relatively concentrated. It destructs the local environment. As long as the tourism point, tourism activity area, the layout of tourism road should not be spread too disperse and messy, the impact of grassland landscape pattern will be significantly reduced, and the deterioration trend of ecological environment is expected to be controlled. Through analysis of different type of tourism activities zone, basic cover all aspects of the impact of grassland tourism development on grassland environment. The changes of grassland soil could be explained driven by tourism disturbance. It can provide alternative methods for tourism interference study and provide guidance for the management of grassland tourist areas. Grassland tourist spots tend to be concentrated in the excellent area of pasture landscape resources and environment, but also the fragile area in ecological environment. The interference of human activities are extremely sensitive whether in a desert steppe zone of brown soil as matrix soil or in typical grassland zone of chestnut soil as matrix soil, and even in the meadow steppe of chernozem as matrix soil. Once vegetation is destructed, soil has been the strength trampling, sandy desertification would grow rapidly. It would not only affect pasture tourism, but also would threaten the neighboring regions. Therefore, it is necessary to study the effect of tourism interference on the soil of grassland tourist spots.
