摘　　要：选取洪河国家级自然保护区沼泽生态系统为研究对象,以生态经济学、资源经济学和环境经济学基本理论为基础,结合遥感与地理信息系统技术,依据沼泽的空间变异性与功能结构分区,通过影子工程法、市场价值法等对水源涵养、气候调节等9项生态功能进行服务价值估算。结果表明,①2009年,9项功能创造的总服务价值为34 274×104元,占洪河地区GDP产值的29%,其中,直接使用价值和间接使用价值分别为5 240×104元和29 034×104元,间接使用价值是直接使用价值的6倍;②单位面积沼泽生态系统提供的服务价值约为5×104元/hm2;9项功能按其服务价值从大到小排序依次为:气候调节价值、洪水调蓄价值、大气成分调节价值、土壤养分保持价值、生物多样性维持价值、休闲旅游价值、水源涵养价值、文化科研价值和物质生产价值。In this paper, marsh in Honghe National Nature Reserve （HNNR） was selected as the study site. With the basic theory of ecological economic and natural resource economic, using geographical information system（GIS） and remote sensing technology, the ecological services of marsh（flood control, gas regulation, et al.） was calculated by monetary methods, such as market value method, shadow engineering method and so on. The results showed that, （1）the total ecological service value of marsh in Honghe National Nature Reserve in 2009 was 342.74 million RMB, which was account for 29% of the GDP value of Honghe region. The direct use value of the ecological service of marsh in Honghe National Nature Reserve was 52.40 million RMB and the indirect value was 290.34 million RMB, indirect use value is 6 times of the direct use value. （2）The aver- age service unit value of marsh was about 5 × 104 RMB/hm2. The values of ecological services ordered by eco- nomic were as follow： climatic regulation, flood control, gas regulation, soil nutrient retention, biological di- versity maintenance, leisure tourism, water conservation, research and culture, and substance production.
