天津滨海新区湿地景观格局变化研究

Study on the Change of Wetland Landscape Pattern in the New Coastal Region of Tianjin

以天津滨海新区湿地景观为主要研究对象,基于ETM/TM遥感及非遥感数据,以1999～2007年为时间尺度,以滨海新区新的行政区划为空间(尺度)范围开展景观格局变化研究。结果表明,湿地景观变化的主要特征是自然湿地和农用地呈减少趋势,盐田、养殖区、建设用地面积有明显增加。整体景观的形状均向着简单化和规则化的方向发展;随着人口与社会经济的发展,人类对景观过程的干预能力也不断提高。

With the wetland landscape in the new coastal of Tianjin as research object,based on the remote sensing and non-remote sensing data of EM/TM,and took 8 years as time scale which from 1999 to 2007,and took new administrative division of new coastal region as spatial scale.The results showed that when the natural wetlands and agricultural lands had a decreasing trend and the area of salt fields,culture area and building site had been increasing obviously,the wetland landscape was chaning.The shape of whole landscape was changing more and more simpler.With the development of popularity and society,the capacity of human disturancing the landscape improved constantly.
