摘要:
为探究踩踏对城市森林公园土壤理化性质及土壤细菌群落分类多样性和功能的影响，该试验以茱萸湾风景区为研究对象，依托江苏扬州城市生态系统定位观测研究站样地，对土壤样品进行采集和分析。应用方差分析、聚类分析和相关性分析，对3种不同踩踏程度（活动区、缓冲区、背景区）、3种不同土层深度（0—10，10—20，20—30 cm）土壤理化指标及其细菌群落的多样性进行初步研究。结果表明：在城市森林公园，踩踏干扰对土壤物理性质的影响在不同程度下、不同土层中表现结果不同，踩踏对土壤结构的正向影响一般发生在土壤中下层。10—20 cm土层，活动区和缓冲区的土壤密度显著低于背景区（P＜0.05）;速效钾含量在重度踩踏下0—10 cm土层以及轻度踩踏下10—20 cm土层中有显著提升;踩踏干扰改变土壤细菌种类及数量，轻度踩踏的缓冲区土壤细菌Alpha多样性Simpson指数显著低于无踩踏干扰的区域（P＜0.05），在门水平上，放线菌门（Actinobacteriota）的相对丰度随踩踏程度的增加而减少,聚类分析显示不同践踏程度对土壤中细菌种类和丰度的影响具有相似性。踩踏对城市森林公园土壤的影响值得长期且持续的研究，合理有效地评价和维护城市森林公园土壤质量，可以为城市森林生态旅游发展提供更多的科学依据。
Abstract:
To investigate the effects of trampling on the soil physicochemical properties and the classification diversity and functions of soil bacterial communities in urban forest parks, this experiment was conducted in the Mastixia Bay Scenic Area, relying on the sample plots of Jiangsu Yangzhou Urban Ecosystem Observation and Research Station. Soil samples were collected and analyzed using variance analysis, cluster analysis, and correlation analysis to evaluate acorss three different trampling levels (activity area, buffer area, and background area) and three different soil depths (0—10, 10—20 and 20—30 cm). The results showed that trampling disturbance had different effects on soil physical properties in different levels and soil layers. The positive impact of trampling on soil structure generally occurred in the middle and lower layers of the soil. The soil bulk density in the 10—20 cm layer of the activity area and buffer area was significantly lower than that of the background area (P<0.05). Regarding soil nutrients, the content of available potassium increased significantly in the 0—10 cm layer of the activity area and in the 10—20 cm layer of buffer area. Moreover, trampling disturbance altered the types and quantities of soil bacteria. The Simpson index of soil bacterial alpha diversity in the buffer area was significantly lower than that in the background area (P<0.05). At the phylum level, the relative abundance of Actinobacteriota decreased with trampling intensity increasing. According to cluster analysis, different trampling levels had similar effects on the changes in the types and abundance of soil bacteria. The impact of trampling on urban forest park soil is worthy of long-term and continuous research. Reasonably and effectively evaluating and maintaining the soil quality of urban forest parks could provide more scientific basis for the development of urban forest ecotourism.
