| 摘要: |
| 以艾里克湖滨绿洲1989年9月的TM, 2000年9月的ETM+和2005年9月的CBERS遥感影像为数据源, 借助RS和GIS技术, 以人机交互方式进行景观分类, 生成景观分类图;运用景观生态学原理, 通过景观统计软件Fragstats For Arcview对研究区景观格局与土地利用变化过程分析并进行驱动力研究.结果表明, 1989-2005年的17年间, 主要在人类活动的影响下, 艾里克湖滨绿洲在外观特征和空间格局均有显著变化, 绿洲面积呈先退缩后扩张趋势, 湖泊面积也呈先萎缩甚至干涸后扩大趋势.整体景观异质性、多样性和丰度下降;景观优势度、蔓延度和破碎化程度增加.要实现干旱区绿洲的可持续发展和景观生态功能的良性发挥, 必须注重景观格局的优化, 从而维护景观生态过程与格局的连续性. |

| Abstract: |
| Using September 1989 of TM, September 2000 of ETM+ and September 2005 of CBERS remote sensing image of Lakeside Oasis in Lake Eric as the data sources, the landscape was classified and the formation of classification map was made by RS and GIS technology and human-computer interactive approach. Using principles of landscape ecology and the landscape statistical software Fragstats For Arcview analyse the driving forces to landscape patterns and land-use change of the study area. Results showed that the 17 years during 1989-2005, the distribution and characteristics of the appearance of lakeside oasis in Lake Eric significantly changed. The oasis area underwent reduce to expansion, and the area of the lake gradually reduced and even dried up. It is essential to intensify the spatial relationships among landscape elements and to maintain the continuity of landscape ecological process and pattern in the course of area expansion. |
