| 摘 要： | 绿洲景观是干旱区受人类活动强烈干扰的区域，也是生态较为敏感和脆弱的部分．本文以武威绿洲为例，运用景观生态学的相关理论、研究方法和数量分析方法，对武威绿洲景观空间格局的现状特征作了初步分析，发现该区域开发利用程度较高的绿洲区，土地利用趋于多样化和均匀化，各类景观类型比例相差不大，景观优势度小，但景观中因人为活动造成的退化景观类型如盐碱地和沙地裸地占有较大的比例，并与耕地镶嵌分布，反映了该区域生态退化趋势较为严重． |

| Abstract: | The oasis is a strangely influenced region by human activities and the ecology is sensitive and vulnerable there. This paper, applying the theory, study and analysis methods of ecological landscape, analyzes the characteristics of the spatial pattern on Wuwei Oasis. Results show that the land use tends to be diversification and equality with small difference of proportion of landscape types and with landscape predominance in the highly exploited oasis area. However, landscapes caused by human activities ,like salt land and sand land, have a large proportion and they alternate with plow land in distribution, indicating a severe degradation of regional ecology. |
