基于高分辨率遥感影像的城市土地利用景观格局分析

Analysis of Urban Land-use Landscape Pattern Based on Remote Sensing Image with High Spatial Resolution

以IKONOS卫星遥感影像为基础数据源,在GIS技术的支持下,获取了泸州市区的土地利用类型。借鉴景观生态学的基本原理和方法,基于Fragstats 3.3软件,用景观格局指数定量分析了泸州市区土地利用景观格局的特征。分析结果表明,泸州市区土地利用景观类型丰富,景观多样性程渡高,景观类型均匀程度也较高,但优势景观类型不明显;由于人类干扰程度较大,土地利用景观破碎,稳定性较差。

Taking IKONOS satellite remote sensing image as study data sources,this paper got classification of land-use landscape in Luzhou City,with the help of GIS.Adopting the basic principles and methods of landscape ecology and based on the software of Fragstats 3.3,this paper quantitatively analyzed the land-use landscape pattern in Luzhou City using landscape pattern indices.The results showed that,Luzhou City,landscape types were abundant and degree of landscape diversity was high.Uniformity degree of landscape type was higher,and absolute landscape type was not obvious.Landscape was broken,and less stable,due to the large degree of human disturbance.
