摘要
以沈阳市为例,对四期遥感影像进行了景观类型分类提取,并分析了城市扩张、景观指数变化以及两者之间的相关性。结果表明:1979～2007年沈阳市城市用地快速增长,耕地逐年减少;景观类型趋于多样化;景观破碎化程度日趋复杂;城市扩张与景观格局变化相关性明显。
Taking Shenyang city for example, the landscape type information was extracted from four remote sensing images, and then land use and landscape indexes were calculated in order to analyze the changes of urban expansion and these indexes as well as their correlation. The results showed that urban land use revealed an upward trend from 1979 to 2007, but the farmland area was reducing year after year; landscape types tended to be of diversification; the fragmentation degree of landscape was increasingly complex; there was an obvious correlation between urban expansion and the change of landscape pattern.
