摘　　要：水生态系统是生态系统申重要的组成部分，其功能强大。本文根据南方圩区水体的特点，定量分析了水体的供水、防洪、滞涝、气温调节、自净作用、物质生产与生物多样性七个方面的功能值，并建立了各项功能值与圩区水面率之间的函数关系。笔者利用该方法对江苏裹下河圩区水体功能进行了定量分析计算，结果表明，方法简便，概念明确，为水体功能价值的计算提供了基础。The water ecosystem is the important composition of ecosystem, and its functions are powerful. According to the characteristics of the water in southern polder area, seven aspects functions of the water were quantitative analyzed in water supply, flood prevention, rainfall flow retardation for water logging control, air conditioning, water self-cleaning, aquatic products provisioning and biodiversity, and their functional relations between each function and the water surface rate have established. The water functions have been analyzed and computed quantitatively by using this method in Li xia he polder area in Jiangsu province, the analysis results finally indicated that the method is simple, the concept is clear, and it can provide the foundation for further calculating the water function values.
