摘要:
运用野外采样调查与实验室分析相结合的方法研究了旅游干扰对鄱阳湖国家湿地公园植被及土壤的影响。结果表明：（1）旅游干扰使得鄱阳湖国家湿地公园植被种类趋于简单，具体表现为植被丰富度指数、均匀度指数、多样性指数和优势度指数均低于对照（CK），并显著降低了草本层植物丰富度指数、均匀度指数、多样性指数和优势度指数（p < 0.05）；（2）干扰在一定程度上造成了土壤中重金属含量及其综合污染指数的增加（Cu，Pb，Cr），显著增加了土壤容重（p < 0.05）和降低了土壤pH、土壤养分和速效养分含量（p < 0.05），但对土壤电导率和全磷没有显著影响（p > 0.05）；（3）土壤速效养分对旅游干扰表现较为敏感，并且旅游干扰导致了土壤性质各指标“表聚性”的消失；（4）旅游干扰区土壤蔗糖酶、转化酶、脲酶、酸性磷酸酶活性和微生物活度均显著低于对照（p < 0.05），从土壤酶活性的变化幅度来看，土壤转化酶活性可以作为鄱阳湖湿地公园土壤健康状况的指示指标；（5）旅游干扰区和对照区土壤微生物数目均以细菌最多，各菌落数目均表现为旅游干扰区域 < 对照区，由此表明了旅游干扰降低了鄱阳湖国家湿地公园土壤微生物数目，对于不同微生物菌落起着不同的效果。
Abstract:
The impacts of tourism disturbance on Poyang Lake National Wetland Park soil and plant properties were analyzed based on the field investigation and the laboratory analysis. The results showed that: (1) the amount of vegetation of Poyang Lake National Wetland Park reduced under the tourist disturbance, and vegetation richness index, evenness index, diversity index and dominance index were lower than CK, tourist disturbance did not significantly affect the tree layer and shrub layer (p > 0.05), but significantly affect the field layer (p < 0.05); (2) tourist disturbance did not significantly affect soil electrical conductivity and total phosphorus (p > 0.05), and soil pH, soil nutrients and available nutrients significantly reduced (p < 0.05), soil bulk density significantly increased (p < 0.05) under the tourist disturbance, the soil heavy metal content and soil comprehensive pollution index significantly increased (p < 0.05); (3) soil available nutrient contents were sensitive to tourist disturbance, which caused that the soil ‘surface accumulation’ disappeared; (4) the soil invertase, invertase, urease, acid phosphatase activity and microbial activity of tourist disturbance zone were significantly lower than CK (p < 0.05), and soil invertase activity could be used as the indicator of soil health of Poyang Lake National Wetland Park through the change of soil enzyme activity; (5) the soil microbial number of tourist disturbance zone and CK were based on bacteria (more than 90%) with the tourist disturbance zone < CK, which suggested that the soil microbial number of Poyang Lake National Wetland Park reduced under tourist disturbance, and tourist disturbance caused the different impacts on different microorganism coenobium.
