摘要
以黄骅湿地为例,在RS和GIS技术支撑下分析了湿地1987~2003年16 a间景观类型间的变化情况,并通过生态环境指数、区域土地利用转变类型生态贡献率评价了景观类型间的转变对生态环境带来的影响。结果表明,黄骅湿地生态环境受到破坏,生态质量下降,其生态环境指数由1987年的0.492变为2003年的0.422;湿地处于退化状态,应加强对湿地的保护。
Based on Geographic Information Systems(GIS) and Remote Sensing(RS),the landscape-change is analyzed in Huang-hua wetland from 1987 to 2003,and the influence on environment was evaluated due to the landscape transit based on eco-environment quality index and contribution rate.The main results and findings include that the environment of Huang-hua wetland was destroyed,the eco-environment quality index dropped from 0.492 in 1987 to 0.422 in 2003.Wetlands is in a degraded condition,and efforts should be made to strengthen the protection of wetland.
