摘要
为正确评估上海市水生态系统的服务功能,参考联合国千年生态系统评估框架,利用上海市的水文水质数据、统计资料和土地利用数据,采用市场价值法、机会成本法和替代工程法等对上海市生态系统服务功能进行了价值评价.研究结果表明：2000 ～2010年水生态系统总价值变化,呈持续上升的趋势,从具体指标来看,2000年和2005年气候调节功能价值最大,其次是航运功能；2010年航运功能最高,其次是气候调节；3个年份功能最少的都是固碳功能；从变化情况来看,生活用水、产业用水、水质净化、输沙造陆等价值持续上升;其他功能如地表水调蓄、气候调节等指标出现了波动,但整体呈现上升趋势.上海市水生态系统服务功能价值巨大,给人类提供了巨大的福利,是上海市城市可持续发展的重要生态支撑系统,需要得到良好的保护.
In order to correctly evaluate the service function of aquatic ecosystem of Shanghai City, by referring the United Nations Millennium Ecosystem Assessment Framework and utilizing hydrological and water quality data, statistic data, land utilization data, the values of aquatic ecosystem services of Shanghai City were evaluated by market value method, opportunity cost method and substitute cost method. The research results show that：（1） in the view of total value of aquatic ecosystem, from 2000 to 2010, the total value increased successively, in which, climate regulation function was biggest in 2000 and 2005, and the next is navigation function; in 2010, the navigation function was the biggest, and the climate regulation came next; carbon fixation was smallest in the above 3 years ; （2） in the view of variation condition, the values of living water use, industry water use, water purification, sediment transport and land formation etc. ,went upward successively, the other function values such as surface water regulation, climate regulation increased generally hut with fluctuation. The service function values of aquatic ecosystem of Shanghai City is giant, providing giant welfare to human, and is the important support system for the sustainable development, so the aquatic ecosystem should be protected well.
