基于马尔科夫模型的芜湖市景观格局演变研究

Dynamic Change in Landscape Pattern of Wuhu Based on Markov Model

在遥感和地理信息系统的支持下,利用1996年和2003年2个时期的Landsat-TM假彩色合成影像作为信息源,获取芜湖市景观类型的转化数据,并结合国土局的土地详查数据,确定相应的转移概率矩阵,应用马尔科夫过程模拟土地类型景观的动态演变情况和未来演变的趋势。结果表明,随着城市化过程的发展,研究区内各种土地类型不断地向城市用地转化。

Based on GIS and KS, making use of Land.sat - TM image of 1996 -2003 period as resource , and the development of landscape pattern in Wuhu were quantitatively analyzed during those two period, and combined the sifting data. The transition probability matrices at two primary states were established. Then, the development and the future tendency of landscape patterns in Wuhu were simulated and forecasted with Markov Model. And the result showed that with the development of urbanization, all different natural areas were tuming into urban area.
