摘要
在遥感与GIS技术支持下,利用景观格局分析软件Fragstats分别计算了研究区内1987、1999和2004年的景观格局指数,对研究区17a来的景观格局变化进行了分析。结果表明:该区域景观整体上处于破碎化过程,尤其是沙地在1987-1999年间迅速扩大,虽然在1999—2004年经过了一定的恢复,景观异质性有所下降,但仍然没有恢复到1987年的水平。
Based on GIS and remote sensing, applying the landscape pattern analysis software - Fragstats, landscape metrics were calculated in 1987, 1999 and 2004 to analysis the dynamic of landscape pattern. The results showed that the landscape pattern of Bashang is in the process of fragmentation as a whole, and sandy expanded rapidly in 1987 -1999. Although landscape heterogeneity has decreased after a certain recovery in 1999 -2004, it still did not return to the level in 1987.
