Soil Vertical Variations In Songshan Scenic Spot And The Influence Of Tourist On Soils

Vertical mountainous region is the proper natural phenomenon. Along with the variety of altitude, the mountainous climate,vegetation,biology,parent population etc also have regular varieties, So the mountain soils represent distinct vertical variations on the vertical zone, and that engender many type of soils. The researth of mountain soil vertical variations can provide us with some basic theories. In the past few years, the international majority of soil classification was the Soil Taxonomy, which was based on the Diagnostic horizon and Diagnostic characteristics, and characterized by quantification, So the Songshan soil classification in Soil Taxonomy can facilitate the international communion and practice.With the rapid development of tourism, we now pay more attention to scenic spot environment than before. We can not easily find soil contamination as a result of its concealment, so we often bring atmosphere,water environment etc to our attention. In virtue of research on tourist activities, we can find out the theories on entironmental content and entironmental appraisement.The vertical variations of soil compositions, properties, types according to genetic classification and taxonomic classification, the impacts of tourist activities were discussed in this thesis based on soil survey in field and soil physical and chemical analysis in laboratory.This thesis can be divided into five parts:Partâ… In this part, the current situation and development tendency of the research about soil vertical variations, the impacts of tourist activities and research status of Songshan soil were generally introduced. Then the author summarized the present situation of the study at home and abroad. At last, the author pointed out the research trends.Partâ…¡In this part, the basic conditions of the research area such as geology,...
