四湖流域湿地景观空间格局研究

采用遥感和GIS技术对四湖流域景观结构进行空间分析，结果表明，四湖各景观类型所占比例差异较大，湿地景观分布不太均匀。各景观类型的破碎度较低，整个流域是以少数大斑块为主体构建起来的。采用分形模型对四湖流域景观要素镶嵌结构的复杂性和稳定性进行分析，证明各种景观要素类型的稳定性和复杂性存在明显差异。稳定性排序与复杂性排序正好相反，越复杂的景观越是不稳定的景观。

The study on landscape space structure of the Four-lake basin

Using the remote sensing and GIS to analyze the landscape structure of he Four-lake basin, the result shows that the proportion of each landscape types differs greatly, and the distributing of wetland landscape is uneven. The fragmentation of the various landscapes is relatively lower. Some large patches, as the minority, become of the main part of the whole area.Furthermore, using the Fractal model, the analysis of complexity and stability of the landscape structure in the Four-lake basin proved that complexity and stability of every landscape types are obvious different each other. The order of the stability is just opposite to that of the complexity, the more complex of the landscape, the more unstable.
