基于GIS和RS技术的楚雄市景观格局研究

A Study of the Landscape Pattern in Chuxiong City Based On Gis and Rs Technology

以2005年楚雄市影像图为基础数据，结合景观生态学的分类方法，应用RS、GIS技术，通过斑块、类型和景观三个水平上景观格局指数对分类后的楚雄市景观格局进行分析。结果表明：楚雄市的景观类型较分散，破碎度化程度较高。森林景观作为楚雄市景观的优势类型，分布较集中；城市景观和草地景观受人为干扰的程度较高，分布较分散；水域景观的分布较分散，并且破碎化程度较高；耕地景观的形状较复杂，在整个景观中具有重要的作用。

Choosing Chuxiong images in 2005 as materials, based on the classification of landscape ecology, applying Remote sensing and Geographic Information System technology in terms of indices, analyzed the landscape pattern in Chuxiong city on three scale levels of patch, class and landscape. The results showed that： Chuxiong City landscape type is dispersive, have a higher degree of fragmentation; Among them, forest landscape advantage on the distribution, The urban landscape and lawn landscape be disturbed, distribution of high degree of a decentralized, The distribution of water landscape scattered, and a high degree of fragmentation; FarmLand landscape shape more complex in the landscape, plays an important role.
