| 摘 要： | 以苏尼特右旗荒漠草原为例分析了荒漠草原的景观格局.结果表明:苏尼特右旗荒漠草原主要是由面积较小的斑块组成,多样性和均匀度均较高,但优势度较低,属于比较匀质的景观类型;景观的破碎度和异质性较高,且有沙化的趋势;锦鸡儿景观、针茅景观和多根葱景观占据着主要地位,其它草地景观居于次要地位;不同景观类型间景观格局差别较大,景观面积越大景观多样性越高.

| Abstract: | The landscape pattern of desert-steppe of Suninteyou district was analyzed.The results showed that it consists of smaller patches and had high landscape diversity and evenness index though low in landscape dominance index,so it was a uniform landscape.There was a high fragmentation and heterogeneity,also it had a trend toward desertification.Caragana landscape,Stipa landscape and Allium polyrrhizum landscape occupied the most important positions;other landscape types were in less important positions.Landscape patterns were completely different with different landscape type;the bigger area it was,the higher landscape diversity it was. |
