世界上最大的芦苇田位于中国东北部的辽河三角洲，历史面积约为1000 km（2）。对芦苇湿地进行了广泛的管理，以最大限度地为造纸业生产芦苇生物量。根据卫星遥感，我们估计芦苇湿地的总面积已从2003年的857平方公里减少到2009年的786平方公里，以适应油田基础设施和社会发展。然而，与此同时，用于生产芦苇浆的芦苇生物质的产量已增加到每年40万公吨。本文叙述了为提高造纸工业用芦苇产量所作的巨大努力，包括（1）从河流中引淡水到芦苇地，（2）地下水位的管理，（3）收获和燃烧以防治害虫，（4）海水灌溉以恢复杂草丛生的芦苇地。造纸业促进了芦苇湿地及其相关生态系统服务的保护。除了是纤维的来源，湿地还为野生动物提供了重要的栖息地，固碳，并为当地人民创造就业机会和经济收入。(C)2014爱思唯尔有限公司版权所有。
The largest Phragmites reed field in the world, with a historical area of approximately 1000 km(2), is located in the Liaohe Delta in northeastern China. The Phragmites wetlands are extensively managed to maximize the production of reed biomass for the paper industry. Based on satellite remote sensing we estimated that the total area of the Phragmites wetlands has decreased from 857 km(2) in 2003 to 786 km(2) in 2009 to accommodate oil field infrastructure and societal developments. However, at the same time the production of Phragmites biomass used for the production of reed pulp has increased to 400,000 metric tons per year. This paper describes the great efforts that have been made to increase the Phragmites yields for the paper industry, including (1) diversion of freshwater from rivers to the Phragmites fields, (2) management of the water table, (3) harvesting and burning for pest control, and (4) seawater irrigation to rehabilitate Phragmites fields infested with weeds. The paper industry has facilitated the conservation of the Phragmites wetlands and their associated ecosystem services. Besides being a source for fiber, the wetlands provide important habitat for wildlife, sequester carbon, and create job opportunities and economic income for the local people. (C) 2014 Elsevier B.V.
