摘　　要：为评估泥炭藓采摘是否对泥炭藓湿地水质有影响,本研究以鄂西南亚高山泥炭藓湿地为研究对象,选择15个水质指标,对比分析未采摘泥炭藓湿地与采摘泥炭藓湿地水质指标差异,采用综合水质指数法(WQI)评估泥炭藓采摘对湿地水质的影响。结果表明:1)相比未采摘泥炭藓湿地,降雨前采摘泥炭藓湿地内COD_(Mn)、DOC显著增加146.95%、144.06%(P<0.05),EC和TDS显著增加59.52%、63.68%(P<0.05);降雨后采摘泥炭藓湿地内CODMn显著增加34.53%(P<0.05)。2)采摘泥炭藓湿地内WQI低于未采摘泥炭藓湿地,水质由III类变为IV类;湿地出水口WQI均高于湿地内,泥炭藓对水质有明显净化作用。3)采摘泥炭藓后导致水质污染的主要来源是可溶性离子和有机物。因此,为更好地保护泥炭藓湿地和水源地,应加大科普宣传且禁止采摘湿地泥炭藓。To assess whether Sphagnum harvesting has an impact on water quality,15 water quality indicators were selected to compare and analyze the differences in water quality indicators between unharvested Sphagnum wetlands and harvested Sphagnum wetlands in southwestern of Hubei Province,and the impacts of Sphagnum harvesting on wetland water quality were evaluated by using the comprehensive Water Quality Index(WQI)method.The results showed that:1)compared with the unharvested Sphagnum wetland,COD_(MN) and DOC in the harvested Sphagnum wetland increased significantly by 146.95%and 144.06%(P<0.05),and EC and TDS increased significantly by 59.52%and 63.68%,respectively before rainfall;and CODMN in the harvested Sphagnum wetland increased significantly by 34.53%after rainfall(P<0.05).2)The WQI in the harvested Sphagnum wetland was lower than that in the unharvested Sphagnum wetland,and the water quality was changed from Class III in unharvested Sphagnum wetlands to Class IV in harvested Sphagnum wetlands;the WQI at the outlet of the wetland was higher than that in the wetland,and the Sphagnum had an obvious purifying effect on the water quality.3)The main sources of water quality pollution due to Sphagnum harvesting were soluble ions and organic matter.Therefore,in order to better protect the Sphagnum wetland and water source,more publicity should be given to popular science and harvesting of wetland Sphagnum moss should be prohibited.
