【摘要】 以ALOS获得的影像(10 m)为原始数据,借助ArcGIS等软件和景观生态学方法分析了科尔沁沙地疏林典型分布区的景观格局特征。结果表明:①研究区景观破碎化程度不高,类型较单一;另外景观以少数几个大斑块为主,并且斑块的形状相对简单且不稳定。②农田和蒙古黄榆疏林是该地区的主要景观类型,分别占到研究区总面积的33.5921%和20.2617%;同时,虽然农田斑块穿插分布于蒙古黄榆疏林斑块之间,但是蒙古黄榆疏林仍然具有大面积成片分布。③研究区流动沙地分布面积较小、斑块数最多、平均斑块面积最小,以固定沙地和半固定沙地为主。更多还原

【Abstract】 Based on remote sensing data(10 m) obtained through the ALOS,the landscape pattern features of the typical sparse forest distribution area in Kerqin sandy land has been analyzed using ArcGIS software and some methods of landscape ecology.The results showed: ① The landscape revealed a lower degree of fragmentation,showed a single style in the research area.And it was dominated by a few large patches and the shape of patch was relatively simple and instability.② Farmland and Ulmus macrocarpa sparse forest were the main landscape types in this area,taking up 33.5921% and 20.2617% separately.At the same time,although farmland patches distributed between the Ulmus macrocarpa sparse forest patches in this area,but there was still a large continuous distribution of Ulmus macrocarpa sparse forest.③ In this area,the bare sand land distributed smaller,the number of patches was the largest and the patch average area was the smallest,and fixed and semi-fixed sandy lands were the main styles.更多还原
