| 摘 要： | 选择武汉市城市发展较快的时间段(1996～2001年)的遥感图片作为信息源提取湿地景观信息,采用部分景观格局指标评价5年间景观格局的变化;利用马尔科夫矩阵计算湿地景观与非湿地景观的转化概率,再据此分析湿地景观格局变化与城市建设之间的关系;根据分析结果提出湿地景观的保护与城市景观建设的协调,使得湿地景观成为城市景观的重要组成部分,突现湿地景观与城市景观部分与整体的不可分割的密切关系.

| Abstract: | The spatial information data on wetland is built up by using 1996 and 2001 remote sensing data as basic information sources and with the Geographic Information System (GIS). Through a selection of the indices such as patch size, fractal density, fractal dimension, fragmentation, diversity and dominance and uniformity index, the dynamic development of wetland landscape pattern in five years is analyzed. Then, transform probabilities from each type of the wetland landscapes to others (including non-wetland landscape) are calculated based on the Markov Model, and the relationship between changes in wetland landscape pattern and urban construction in Wuhan City is discussed. The analytical result shows that urban wetland landscape is one of important components of the urban landscape of Wuhan City and, therefore, the wetland landscape should be protected. |
