Influence of eco-agriculture tourism on soil environment in karst region A case study in Hongyan village, Guangxi

The development of eco-agriculture tourism has some connection with soil environment. The ecotourism attraction zone in Hongyan village, Gongcheng county is taken as an example to analyze the influence of tourism on soil physical and chemical properties in the paper. In terms of physical and chemical properties, the fertilization of fruit orchard soil in Hongyan village is higher than that of any other region in Guangxi and the soil pH value is gradually developing towards that in the maturity soil. The organic matter content equals to what is needed in fruit orchard as long as 30 years and the content of nitrogen, phosphor and potassium is also generally increase, All the positive influence may attribute to the Hongyan village＇s intensive cultivation of eco-agriculture tourism resources taken for promoting its eco-tourism activities. However, in the vicinity of tourism passage, some physical properties have slightly changed which makes porosity of soil narrowed down, which is considered as the negative influence brought up by the tourism on soil.
