摘要
在遥感和地理信息系统的支持下,利用1996年和2001年两个时期的Landsat-TM假彩色合成影像作为信息源,获取武汉市湿地类型的转化数据,确定相应的转移概率矩阵,应用马尔科夫过程模拟湿地景观的动态演变情况和未来演变的趋势.结果表明,武汉市主要湿地类型面积都有减少趋势,而建设用地有增加的趋势,说明城市化对于湿地景观各具有很大影响.
Based on dynamic changes of wetland l types from remote sensing data at 1996～2001 period, the development of wetland landscape pattern in Wuhan are quantitatively analysed during those two periods. The transition probability matrices at two primary states(1996 and 2001) are established. Then, the development and the future tendency of wetland landscape patterns are simulated and forecasted with Markov process. And the result shows that most natural wetlands areas are increasing and urban area is decreasing, which shows urbanization process has great impact on wetland landscape pattern.
