| 摘 要： | 利用TM、ETM+遥感影像,通过遗传神经网络分类方法提取了1995～2010年贵阳市土地利用/覆盖类型变化(LUCC)信息,并分析了LUCC的空间分布特征和近15a来的整体变化情况.结果表明:林地、草地、农作和裸地、建设用地和水体是贵阳市的主要地表类型,其总体变化特征为城市建设用地扩张明显,水体、草地面积保持平稳,农田和裸地面积减少,林地面积稳步增加.

| Abstract: | In this paper,using the TM and ETM+ remote sensing images,we got the information of the land use/cover change in Guiyang by the classification method of genetic neural network,and analysised the overall changes and spatial distribution of LUCC between 1995 and 2010.Results showed that woodland,grassland,cropland/barren,land used for construction and water bodies are the main surface types of Guiyang,and their overall changes concluded that land used for construction in urban expanded obviously,water bodies ... |
