Research On Impact Of Tourism Activities On Desert Descending Slippery Sand Area

In recent years,the northern region(especially in the northwest region) desert tourism rapid development, and to bring economic benefits to the local at the same time, too many tourists swarm, caused different degree to the local ecological environment destruction, is beyond the capacity of tourist environment., descending scenic area have increased in recent years, tourists, visitors has reached millions of people in 2010. But according to statistics, to observe the influence of tourists to the scenic spot speed and scenic spot cannot reach the speed of the balance of natural recovery, especially in the scenic spot slippery sand project of the natural environment has been deteriorating rapidly. Slippery sand by visitors and tourists trample on foot slippery sand activities and natural environment, under the influence of slope gradually slow, upper slope into ward trend, lower slope into extension trend, to a large extent influence the scenic landscape effect and tourists slippery sand experience. This research mainly on the impact of tourism activities on the desert scenic spot slope form and field survey and measurement, an impact type of desert tourism scenic area, especially with slippery sand project development and ecological restoration to provide theoretical basis for the protection of the scenic area, and combining with related theory, adopts the advanced technology, to explore the mechanism on the impact of tourism activities on the scenic area, reasonable of tourism environment carrying capacity.Research using real-time dynamic positioning technology (RTK) on the micro scale of descending in October、April Ⅰ、August of 2014 and in March of 2015, get the scenic spot slippery slope four times of the topographic map, and with the aid of Arc GIS software will topographic map generation model, on the slope, slope variability and cross section analysis; Then obtain topographic map in 1995, 2003,2009 and 2013 remote sensing film such as basic data, based on the GIS software on macro scale analysis of the study area, and then adopt the method of superposition of contrast in different periods of the image, to look at the sliding sand slope change in recent 10 years. By total station measuring technology for sand slope bottom tree height measurement, at the same time in different functional areas to select samples of trees, and trees are slope buried node set scale, by reading the data scale, so as to verify the study area sand slope bottom depth value of the trees buried by sand dunes. Finally combining with descending weather stations rainfall and wind direction data and characteristics of tourists and visitors to correlation research of sliding sand slope, finally come to the conclusion that human factors and the impact of natural factors on slope change respectively.Study found that descending slide in sandy slope steep fall trend in recent years, and has a great correlation with the size of the visitors, when visitors must have different behavior characteristics of tourists the effects on the slippery sand area also has a great difference. If do not take feasible measures, will seriously affect the capacity of the scenic spot and tourist experience, a threat to the scenic spot north of Baolan railway and 201 provincial highway safety, and even affect the scenic area south of the Yellow River wetland ecological security.
