烧烤类旅游活动对土壤环境的影响

The Impact of Barbecue Tourism Activities on the Soil Environment

摘要: 通过野外调查采样和室内分析相结合的方法，分析测定了烧烤类旅游活动对土壤环境理化性质的影响，并将各指标变化率与距中心区距离进行相关性分析。结果显示：1) 节事旅游活动会对土壤物理性质产生显著影响，结果发现游客高强度的践踏活动会导致土壤容重增大，而随着土壤紧实度提高，容重增大，土壤含水率则会随之降低。2) 游客在进行烧烤类旅游活动时，大量的外界有机物质会随之进入土壤环境。这些有机物质将会改变土壤的化学性质，主要导致土壤有机质含量以倍数级别迅速增大。3) 土壤容重变化率和土壤有机质变化率均与距活动中心区之间的距离呈负相关；土壤含水率变化率与距活动中心区之间的距离呈正相关；容重变化率与含水率变化率呈负相关。

Abstract: The influence of barbecue tourism activities on the physicochemical properties of soil environment was analyzed by combining field survey sampling and indoor analysis, and the correlation between the rate of change of each index and the distance from the central area was analyzed. The results showed that: 1) The festival tourism activities will have a significant impact on the physical properties of the soil, and it is found that the high-intensity trampling activities of tourists will lead to an increase in soil bulk density, and as the soil compactness increases, the bulk density increases, and the soil moisture content will decrease. 2) When tourists carry out barbecue tourism activities, a large amount of external organic matter will enter the soil environment. These organic matters will change the chemical properties of the soil, mainly resulting in a rapid increase in the content of soil organic matter at multiple levels. 3) The rate of change of soil bulk density and the rate of change of soil organic matter were negatively correlated with the distance from the active central area; the rate of change of soil moisture content was positively correlated with the distance from the active central area; and the rate of change of bulk weight was negatively correlated with the rate of change of moisture content.
