摘要
以渤海新区1970,2000,2009年卫星遥感影像为基础,综合利用RS,GIS方法,解译并分析了研究区近40年间湿地的变化情况。结果表明,研究区在监测时段内湿地面积变化明显,湿地面积总量保持上涨趋势。不同湿地类型面积在不同监测时间段均有明显且不同程度的变化,湿地面积的变化方向有差异。
This paper interpreted and analysised the changes of wetland in Bohai new area, comprehensively used the method of remote sensing and geographic information system, based on the satellite remote sensing image of 1970, 2000, 2009. The results show that the changes of wetland area are significant, the total area of wetland to maintain the upward trend. The changes of the different types of wetland are obvious with different degrees in monitor period ; there are differences in the changes of wetland area.
