摘 要:湿地生态系统具有强大的功能,是人类生存和社会经济发展的基础。不同利益相关者对湿地生态系统服务的认知不同,农户对于生态系统服务的认知、影响因子和原因缺少系统的了解和分析。本文采用调查问卷,对湖区3个县12个村的310户农户的基本信息、农业生产、渔业捕捞、湿地保护和生物多样性作深入了解,重点调查鄱阳湖区湿地生物多样性、调节气候、水质净化和水产品等服务,并利用SPSS进行二元logit分析。研究结果表明:①鄱阳湖区农户对湿地生态系统服务认知最充分的是调节气候、生物多样性和水产品;②不同调查区的农户,对在旅游休闲、纤维和燃料、水产品和植物产品等生态系统服务重要性的认知存在差异;③性别、年龄、职业和总收入是影响农户对生态系统服务认知的主要因素。Wetland ecosystems characterized by a broad variety of biodiversity as well as ecological, economic and cultural functions provide a quantity of resources for human and production, and play a critical role in balancing the ecological systems. It is considered a base for human survival and social and economic development. Different stakeholders would have different definitions about wetland ecosystem services. Even though countries and governments have fully recognized ecosystem services, there has little comprehensive analysis and understanding associated with farmers’ perception about wetland ecosystem services, factors and reasons. In the present work, the author performed a questionnaire survey on this. The questionnaires comprised of more close-ended questions and less open-ended questions were designed and 310 questionnaires were sent to 12 villages in three counties. Then the authors looked into the general information on farmers and agricultural production, fishing, wetland conservation and biodiversity. The Poyang Lake areas investigated in the study belong to the waters of Poyang Lake and lake islets, ranging in latitude roughly between 28°11′ N to 29°51′ N and in longitude between 115°31′E-117°06′E. They contains 12 cities and counties, covering an area of 20,970 km2 and accounting for 12.6% of the total area of Jiangxi Province. The Poyang Lake areas are grain, cotton, oil, and fish production base. The authors utilized SPSS 16.0 for statistical analysis for the survey. Results indicated that farmers showed more sound understanding of sustainable wetland ecosystem services related to their own interests. Higher perception includes functions of weather regulation, biodiversity, fishery products, water purification, plant products, tour and recreation. Different farmers in different survey plots would show appreciable differences in the importance of wetland ecosystem services, such as tour and recreation, fiber and fuel, fishery products and plant products.
