| 摘 要： | 通过对天津1993、1998、2004、2006年的遥感影像解译,探索新区开发过程中湿地类型的转化过程、内、外部原因机制,并根据已有湿地生态系统服务价值的研究,讨论变化引发的后果和影响。结果表明,从1993年至2006年,滨海新区湿地、湿地中天然湿地类型面积减少;从转化的趋势来看,湿地类型向着居民点及建设用地转化,天然湿地向着人工湿地转化。这些转变既带来了丰厚的经济效益也会对当地生态系统造成一定的影响,改变湿地生态系统的格局和功能。

| Abstract: | Through the comprehensive analysis of remote-sensing images of Tianjin Binhai New Area,this research explored the transformation of wetland and it's intrinsic and extrinsic reasons,discussed the effects of changes.The outcome showed that a lot of wetlands have been lost from 1993 to 2006.The main trend of translation was from wetlands to city,besides the natural wetlands change into constructed wetlands.These changes brought some economical benefit,but they also affected the pattern of ecosystem and its functions. |
