摘　　要：根据实地调查和相关文献分析,对蚌埠市三汊河湿地的生态系统进行了分类。将湿地分为自然湿地和人工湿地两大类,永久性河流、季节性河流、芦苇沼泽、灌溉水渠、养殖池、稻田湿地6小类。对自然湿地和人工湿地的水文调节、固碳、水体净化、物质生产、旅游科研、提供生境等6项生态系统服务功能价值进行评价和估算。结果表明三汊河湿地的生态系统服务功能总价值为2157.23万元,自然湿地水文调节功能的价值最高,其次是固碳功能价值,水体净化功能的价值最低;人工湿地的物质生产功能的价值最高,水文调节功能的价值最低。由此推出,自然湿地的功能以生态服务为主,人工湿地的功能以生产服务为主。依据湿地生态系统服务功能的价值评价结果,对三汊河湿地的保护和利用提出建议,以期为湿地资源和功能的利用提供参考意见。Sanchahe Wetland is located at Huaishang region of Bengbu city, which lies in the middle reaches of Huai River. Long time ago Sanchahe was a canal for human beings and many weeds distributed around it. In the 1950s; 4 levees were built there that divided the wetlands into 2 parts. The eastern part was exploited to plant paddy and the western one was reserved as natural condition. Therefore Sanchahe Wetland could be divided into 2 major ecosystems： the natural wetland and the constructed wetland. Below them wetland types should be put into 6 categories based on classification system of wetland types in China, which are permanent rivers, seasonal river, weed, irrigation canal, pond and paddy field. Among which weeds were consisted of Phragmites autstralis and Scirpus triqueter. Wetlands resource was abundant and various there. Hypsography of 1 ： 10 000 and investigation results were used to draw the spatial distribution map of different wetland types. ArcGIS9.0 software was applied to survey area data of different wetland types. And some economic methods were quoted for ecosystem services valuation. Parts of the statistical data were obtained from field research, like water capability of Sanchahe Wetland, carbon absorption of plant and annual output of product in wetlands. Parts of the data were obtained from other researches, such as purification of pollutant, value of habitat provision in wetlands. As a result, total area of all the wetlands is almost 5.23 km^2. Natural wetland including permanent rivers, seasonal rivers and weeds are 3.36 km^2. Among them weeds are 3.12 km^2 occupying 59.66% of the total area. Constructed wetlands including irrigation canals, ponds and paddy fields are 1.87 km^2, among which paddy fields are 1.48 km^2 occupying 28.30% of the total area. Ecological services and economic value of various wetland types were assessed by 6 functions ： water regulation, carbon fixation, water purification, product provision, tourism and scientific researches, habitat provision.
