摘要: 以QuickBird卫星影像解译的贵港市城市建成区景观类型图为基础,选取合适的格局指数对该区域的景观格局进行了分析。结果表明,整个景观区为一个较典型的居住、公共市政和工业用地城市景观镶嵌体;整个景观的多样性指数和景观破碎度比自然景观高5.1%~64.7%;各种不同类型城市景观的斑块面积及形状复杂程度和破碎度差异明显。

Abstract: Based on the landscape classification map interpreted by high-resolution QuickBird imagery,the landscape structure of Guigang City was analyzed.The results showed that the whole landscape was a typical mosaic of residential land,municipal public utility land,and industrial land.The Shannon diversity indices and fragmentation indices of the landscape were 5.1%~64.7% higher than those of the natural vegetation landscape,and the differences in shape complexity and fragmentation of key landscape elements were obvious.
