中文摘要	基于研究区2001年Landsat7 ETM+遥感影像资料,综合运用遥感与GIS技术手段,利用景观格局分析软件APACK分别从景观生态类型面积统计、景观水平指数、斑块类型水平指数及斑块类型间水平指数定量化分析了2001年额济纳天然绿洲景观空间格局特征,并结合研究区1987年和1994年的景观格局指数进一步探讨了关于格局指数间的相关性问题.研究结果表明:①研究区景观具有典型的"基质-廊道-斑块"结构特征;②研究区景观具有较高破碎化、较低多样性及粗糙质地特征,景观稳定性差;③各景观格局指数相互之间并不完全独立,有些指数之间具有明显的相关性.
英文摘要	The Ejin natural oasis landscape lies in the lower reaches of the Heihe river basin in the arid interior regions of northwestern China.With decreasing water resources from the upper reaches of the Heihe river basin,many urgent ecological and environmental issues in the Ejin natural oasis have become more pressing in recent years.Analysis on landscape patterns not only can clarify the characteristics of the natural oasis landscape spatial structures,but also can provide a scientific basis for the study of the landscape degradation,protection and its sustainable development.Using remote sensing techniques,GIS,and landscape pattern analysis software APACK,the landscape patterns of Ejin natural oasis landscape are studied respectively from the aspects of area statistics,indices at landscape level,indices at classes level and indices between attribute classes based on Landsat 7 Enhanced Thematic Mapper plus data in 2001.Moreover, correlation analysis between different landscape indices is carried out with the integration of Ejin natural oasis landscape indices in 1987,1994 and 2001.Results show that: 1) typical"matrixcorridor-patch" landscape structure was shown in Ejin natural oasis landscape; 2) it was not steady for Ejin natural oasis landscape with high fragmentation,low landscape diversity,and coarse landscape texture; and 3) it was not independent of each other between different landscape indices, and the relations between some of the indices was obviously correlated with each other. Furthermore,the authors suggest that it should be careful to select some of the landscape indices during landscape patterns analysis.
