Wetland Ecosystem Service Value Analysis and Forecast in TBNA
利用遥感与GIS分析天津滨海新区1984-2008年湿地景观变化，计算生态服务价值，并预测两种情景下2009-2020年的价值变化，发现湿地保护计划可缓解社会发展压力。
Taking the landsat TM images in 1984,1995 and 2008,and the present land use map of 2004,and the other data of Tianjin Binhai New Area(TBNA) as the basic information resources,this paper analyzed the landscape changes of TBNA wetlands in 1984-2008 by RS and GIS.The provisioning,regulating,cultural and supporting ecosystem services were chosen as the main functions of the wetlands of TBNA.With local environmental experts investigation,the ecological service value of TBNA was calculated by the evaluation system.Under the two scenarios‘WWP’and ‘WP’,the area of wetlands develops toward different direction.With the evaluation system,we calculated the ecological service value from 2009-2020 under the two scenarios,we concluded that the wetland protection plan will alleviate the stress from social development.
