| 摘 要： | 应用遥感与地理信息系统技术,结合辽河三角洲地区实际情况分别对该地区1988、1998、2008年3期遥感影像进行分类、解译,系统地获取地区景观格局状况,分析动态变化特征,并运用CA-Markov模型对未来湿地景观格局进行模拟预测。结果表明:在1988-2008年辽河三角洲地区湿地景观格局随时间变化明显。具体表现在自然景观类型面积不断减小,人为景观类型面积不断增大;近海地区景观格局变化剧烈,内陆地区景观格局变化趋于稳定;同时通过CA-Markov模型对2018年景观格局进行预测可以发现景观格局未来将继续向人为驱动方向发展,人类活动将对该地区景观格局变化产生更为深远的影响。

| Abstract: | Remote sensing images of the Liaohe Delta wetland in year of 1988,1998 and 2008 were analyzed with the tools of RS and GIS regarding its dynamic characteristics.At the same time,by using CA-Markov model future landscape of the Liaohe Delta wetland was predicted.Studies of situation change of the landscape pattern in Liaohe Delta wetland during 1988-2008 and its predicted situation in the year 2018 indicate that the change of landscape pattern in the Liaohe Delta wetland was mainly driven by human activities,whose far-reaching impact on the landscape pattern will continue. |
