- 摘要:
- 为探明旅游活动对香山公园生态环境的影响，采用样方法和室内分析相结合，对香山景区主要游览步道附近土壤及植被进行了调查分析。结果表明：（1）旅游活动降低了香山公园草地丰富度指数和多样性指数（p < 0.05），但并没有影响均匀度指数和优势度指数（p > 0.05）；（2）旅游活动显著降低了草地枯落物厚度、土壤含水量（p < 0.05），而显著增加了土壤容重和pH（p < 0.05）；（3）旅游活动下草地土壤有机碳、全氮和全钾均显著低于对照（p < 0.05），而土壤全磷与对照没有显著差异（p > 0.05），这说明旅游活动对土壤全磷并无显著影响；（4）旅游活动区和对照区土壤养分随土层深度的增加呈下降趋势，以0—5 cm土层（表层）最高，呈现出明显的"表聚性"，10—15 cm土层内土壤养分含量最低，5 cm土层以下旅游活动和对照区域土壤养分急剧下降，相同土层内均表现为旅游活动区域 > 对照区，旅游活动并没影响土壤养分垂直分布；（5）相关性分析表明旅游活动区域和对照区域土壤养分之间均呈极显著线性正相关（p < 0.01），说明了香山公园草地土壤系统内部因子处于动态变化和平衡中，同时也表明旅游活动对土壤生态系统有一定影响，而此影响并没有改变土壤养分因子之间的互作效应。
- Abstract:
- In order to understand the impacts of tourist activities on ecological environment, sampling and lab analyses were conducted to survey the soil and plant near the Xiangshan Park. The results were as follows: (1) the richness index and diversity index in the grassland had significantly reduced (p<0.05) under tourist activities, and tourist activities had no effect on dominance index and evenness index (p>0.05); (2) the litter thickness and soil moisture content had significantly decreased(p<0.05) and soil bulk density and pH had significantly increased (p<0.05); (3) soil organic carbon, total nitrogen and total potassium had significantly decreased (p<0.05) and tourist activities had no effect on soil total phosphorus (p>0.05); (4) soil nutrients of tourist activity areas and control areas declined with the increase of soil depth which were mainly concentrated in the 0—5 cm soil layer and showed the surface accumulation, while soil nutrients decreased sharply below 5 cm depth. In the same soil layer, soil nutrients of tourist activities area were richer than those of the control area, we could concluded that tourist activities had no effect on profile distribution patterns of soil nutrients; (5) correlation analysis showed that soil nutrients of tourism activities area were significantly positive linear correlation with those in the control areas (p < 0.01), which suggested that tourism activities had the effects on soil ecological system and the soil factors were in dynamic balance, respectively, however, this effect had not changed interaction effect of the soil nutrients.
