| 摘 要： | 以1976年MSS、2001年ETM和2007年CBERS为数据源,利用人机交互目视解译和野外检验方法获取湿地数据,在GIS技术的支持下,利用动态度、转移矩阵、景观格局指数和质心迁移模型,揭示了东北三省湿地景观的时空变化特征。结果表明:30年来东北三省天然湿地大量减少,趋于复杂化;人工湿地快速增加,趋于大规模规则化;大量沼泽湿地转化为人工养殖种植景观;尽管近期在降水增多及采取湿地保护措施下使天然湿地略有增加,但海岸湿地退化趋势仍较明显。

| Abstract: | Using the MSS data in 1976,ETM data in 2001 and CBERS data in 2007 as data source,we obtained the wetland data by the way of man-machine interactive interpretation and field checkout.Under the support of GIS technology,the authors analyzed the spatial-temporal change characteristics of wetland by dynamic degree,conversion matrix,landscape pattern index and barycenter excursion in three provinces of Northeast China.The results show that the natural wetland decreased largely,and landscape pattern tend to comp... |
