| 摘 要： | 从历史演化和景观格局动态变化两个方面对天津滨海新区湿地生态系统的演变进行了研究。历史上天津地区为海洋,自滨海新区成陆以来,经历了多次的海浸和洪水淹没,海浸期间发生陆地湿地化,海退和洪水退却时发生水体湿地化。本文总结了自地质时期以来的历史演化模型。同时在GIS和RS技术支持下,运用FRAG-STATS软件,研究了1979-2008年滨海新区湿地景观格局动态变化特征。结果表明,随着滨海新区的发展和土地利用强度的增大,研究区景观斑块数量增加、平均斑块面积减少的趋势比较明显,景观呈现破碎化的趋势;总体上,近30年中,滨海新区湿地总面积变化不大,并没有大面积持续减少。景观破碎程度从1979年开始持续上升,中间略有波动,但总体上升较快。

| Abstract: | Wetland environment evolvement and dynamic change of wetland landscape patterns in Binhai new area of Tianjin were studied.Tianjin area was sea in history.Since Binhai new area became terrene,the area had been experienced time after time flood and transgression.The evolvement model was put forward from antiquity,the dynamic change characteristic of the wetland landscape pattern of Binhai new area was analyzed utilizing the FRAGSTATS software on the basis of GIS and RS from 1979 to 2008.The results showed th... |
