Deltaic flood plains provide critically important ecosystem services, including food production, fresh water, flood control, nutrient cycling, spiritual values and opportunities for recreation. Despite growing recognition of their societal and ecological importance, deltaic flood plains are declining worldwide at alarming rates. Loss of wetland ecosystem services bears socio-environmental costs overlooked in land-use planning. Conversely, wetland restoration can deliver important long-term benefits. This paper examines effects of different land use policies on ecosystem services provided by the Danube Delta, one of Europe’s largest and most outstanding wetlands. First, we identify, characterize and measure the most important ecosystem services provided by the Danube Delta. Second, we assess trends between 1960 and 2010, contrasting periods of economic development (1960–1989) and ecological restoration (1990–2010). Our results indicate that i) the Danube Delta provides important services with benefits accrue from local communities to humanity at large, ii) that two thirds of the Delta’s ecosystem services have declined over the studied period and iii) that ongoing restoration efforts have so far been unable to reverse trends in ecosystem service decline. Benefits from ecological restoration policies are already becoming apparent, but at a scale not yet comparable to the costs from ecosystem decline incurred over previous decades.

湿地丧失和恢复带来的生态系统服务变化:多瑙河三角洲的生态系统评估(1960–2010年)

三角洲洪泛区提供至关重要的生态系统服务,包括粮食生产,淡水,防洪,养分循环,精神价值和娱乐机会。尽管人们日益认识到其在社会和生态上的重要性,但三角洲泛滥平原在世界范围内的下降速度惊人。湿地生态系统服务的损失承担了土地利用规划中忽略的社会环境成本。相反,湿地恢复可以带来重要的长期利益。本文研究了不同的土地使用政策对多瑙河三角洲(欧洲最大,最杰出的湿地之一)提供的生态系统服务的影响。首先,我们确定,表征和衡量多瑙河三角洲提供的最重要的生态系统服务。其次,我们评估了1960年至2010年之间的趋势,经济发展时期(1960年至1989年)和生态恢复时期(1990年至2010年)形成鲜明对比。我们的结果表明:i)多瑙河三角洲提供重要服务,而当地社区对整个人类都有好处; ii)在研究期间,三角洲三分之二的生态系统服务有所下降; iii)迄今为止,正在进行的恢复工作无法扭转生态系统服务下降的趋势。生态恢复政策的好处已经变得显而易见,但其规模尚无法与过去几十年中因生态系统衰退所造成的损失相提并论。ii)在研究期内,三角洲地区三分之二的生态系统服务已下降,并且iii)到目前为止,正在进行的恢复工作未能扭转生态系统服务下降的趋势。生态恢复政策的好处已经变得显而易见,但其规模尚无法与过去几十年中因生态系统衰退所造成的损失相提并论。ii)在研究期内,三角洲地区三分之二的生态系统服务已下降,并且iii)到目前为止,正在进行的恢复工作未能扭转生态系统服务下降的趋势。生态恢复政策的好处已经变得显而易见,但其规模尚无法与过去几十年中因生态系统衰退所造成的损失相提并论。
