摘要
从遥感技术特点出发,以黑土区为研究对象,运用景观生态学研究方法,在斑块类型水平和景观水平两个层次上选取10种景观格局指数对1990~2000年黑土区景观格局变化特点进行分析。结果表明：耕地是该区的主导景观类型;10年来耕地面积逐渐减少,建设用地和其他类面积均增加;区内各景观存在破碎化趋势。
Combining the advantage of remote sensing technique and using the methods of landscape ecology,the author selected 10 landscape indices and analyzed the change character of landscape pattern from patch-level and landscape-level from 1990 to 2000. The result shows that：The farmland is the dominant landscape in this region; In the past 10 years,the area of farmland is decreasing and construction land and others is increasing; Every landscape exist fragmented trend.
