Abstract: With the continuous improvement of the quality of life of urban and rural residents， suburb tourism activities in the mixed Agricultural-pastoral zone are becoming increasingly popular. Focusing on stampede interference activities along scenic roads， the impact range and degree of stampede interference on the vegetation-soil system along the mixed Agricultural-pastoral zone are calculated through field investigations， Weibo location analysis， and remote sensing image analysis. The results show that trampling has a strong impact on vegetation height， coverage， and soil hardness. The average Index of Land Cover Impact （ILCI） was 49.58， indicating a moderate level of disturbance overall. Weibo location analysis showed that 80% of trampling activities were concentrated within 800 m of the scenic road， with the most concentrated within 250~300 m. OpenStreetMap data analysis of NDVI changes in different buffer zones showed that trampling disturbance had an interference range of 200 m on the vegetation-soil system along the mixed Agricultural-pastoral zone. The research conclusion helps to enhance the scientificity of tourism management. By reasonably formulating the capacity of rural tourism environment， regulating the flow of rural tourism activities， and other measures， the impact of excessive human trampling on the vegetation-soil system along scenic roads can be effectively alleviated.

摘要： 随着城乡居民生活质量的不断改善，农牧交错带郊野旅游活动日趋流行，聚焦风景道沿线的踩踏干扰活动，通过实地调查、微博位置分析、遥感影像分析测算踩踏对农牧交错带沿线植被-土壤系统的影响范围和影响程度。结果表明：踩踏对植被高度、盖度和土壤硬度影响较强烈，地表盖度响应指数（Index of land cover impact，ILCI）平均值为49.58，整体处于中等干扰程度，通过微博位置分析得出80%的踩踏活动集中在距风景道800 m内，在250~300 m范围内最集中，通过公开地图（OpenStreetMap，OSM）数据不同缓冲区归一化植被指数（Normalized difference vegetation index，NDVI）变化分析得出踩踏干扰对农牧交错带沿线植被-土壤系统的干扰范围在200 m以内。研究结论有助于提升旅游管理的科学性，通过合理制定郊野旅游环境容量，规范郊野旅游活动路线和人流等措施，可有效缓解人为过度踩踏对风景道沿线植被-土壤系统的影响。
