- 摘要:
- 采用野外采样调查与实验室分析相结合的方法，对不同旅游干扰强度（High Disturbance，HD；Middle Disturbance，MD；Lower Disturbance，LD）下的湿地公园土壤酶活性及水质进行了研究。结果表明：随旅游干扰强度的增加，土壤蔗糖酶、脱氢酶、脲酶和磷酸酶活性均明显降低，MD，HD与对照达到显著差异水平（p < 0.05），而LD与对照未达到显著差异水平（p > 0.05），即轻度旅游干扰对土壤酶活性影响并不大；土壤酶活性垂直分布均表现出明显的“表聚性”，而旅游干扰导致土壤酶活性的“表聚性”趋于消失，并且旅游干扰并没有影响深层（40—60 cm）土壤酶活性；从土壤酶活性的变化幅度来看，土壤蔗糖酶活性和脲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；随旅游干扰强度的增加，TN，TP，NH4+-N，BOD5，CODCr和高锰酸钾指数均明显增加，TP，NH4+-N增加幅度较大，对旅游干扰表现较为敏感，其中MD，HD水质中TN，TP，NH4+-N，BOD5，CODCr和高锰酸钾指数与对照达到显著差异水平（p < 0.05），表明了旅游干扰降低了鄱阳湖国家湿地公园水质状况，导致其水质出现轻微的富营养化，但轻度旅游干扰对鄱阳湖水质影响并不大。相关分析结果显示鄱阳湖国家湿地公园土壤酶活性与水质状况呈显著或极显著正相关，由此表明旅游干扰条件下，土壤水质状况更大程度上依赖于土壤酶活性。
- Abstract:
- The impacts of tourist disturbances (High Disturbance, HD; Middle Disturbance, MD; Lower Disturbance, LD) on soil enzyme activity and water quality in Poyang Lake National Wetland Park were analyzed based on the field investigation and the laboratory analysis. The results showed that the activities of soil urease, sucrase, dehydrogenase and phosphatase significantly decreased with the increase of tourist disturbance in tensities, MD and HD were significantly different from CK (p < 0.05), LD was not significant difference with CK (p > 0.05), the middle tourist disturbance had no effect on soil enzyme activity. The vertical distribution of soil enzyme activity had obvious surface accumulation, the surface accumulation tended to wear off because of tourist disturbance, and tourism disturbance had no effect on soil enzyme activity in 40—60 cm depth. Soil invertase and urease activities could be used as the indicators of soil health in Poyang Lake Wetland Park because their rangeability was larger. TN, TP, NH4+-N, BOD5, CODCr and permanganate index significantly increased with the increase of tourist disturbance, TN and NH4+-N were sensitive to tourist disturbance. The contents of TN, TP, NH4+-N, BOD5, CODCr and permanganate index of MD and HD were significant difference with CK (p < 0.05), which indicated that tourist disturbance had reduced the water quality of Poyang Lake National Wetland park and led to the light water eutrophication, however, the middle disturbance (MD) had the slight effect on the water quality of Poyang Lake National Wetland park. Correlation analysis indicated that the soil enzyme activity was significantly or extremely significantly positively related to the water quality, which suggested that the soil water quality was more dependent on the soil enzyme activity.
