| 摘 要： | 在ERDASIMAGE中对白洋淀流域2000年的TM数据解译处理,并在ARCGIS和景观结构分析软件FRACSTATS软件的支持下,计算出不同高程带下景观格局指数,并做进一步的分析,结果表明:白洋淀流域景观格局受高程影响显著,分别表现在景观水平和景观要素类型上,空间格局特征随高程呈有规律的分异,但是人为景观类型耕地和居民点表现出与自然景观草地和林地随高程变化不同的分异特征。同时,白洋淀流域东部的人为景观与西部的自然景观也表现出不同的景观格局特征。耕地作为白洋淀流域的主要景观类型,对各个高程带的总体景观格局影响很大。而丘陵区由于其位于农牧和林牧交错带,也表现出与其它高程带不一致的格局特征。 |

| Abstract: | By interpreting the TM data of Baiyangdian Watershedin 2000 with the ERDAS IMAGEas the basic information and with the supportof ARCGIS and FRACSTATS, the indexes of landscape patterns in different elevationzones were calculated, and the further analysis was taken. The results showed that: landscape patterns affected by elevation distinctly. The changes of patterns of artificial landscape types such as cultivated landand resident sites differed with the nature resources such as grassland and woodland. At the same time, the artificiallandscape in eastwere different from the nature landscape in west. Cultivated land as the biggest landscape type had a great influenceon the landscape patterns of every elevation zone .The landscape of eco-tone between cultivated land and grazing land or forest and grazing land were more vulnerable and the pattern was instability. |
