摘要
以1992年和2000年唐山市两期Landsat TM/ETM遥感影像数据为主要数据,在影像分类的基础上,进行土地利用信息的提取,并借助于GIS软件对唐山市土地利用变化进行分析。结果表明:唐山市各区土地利用均处于发展期,且各区土地利用变化幅度和速度的空间分异显著;唐山市耕地急速减少,城市化水平显著提高,耕地减少与居工地增加有明显的相关性。
Abstract： The paper, taken two landsat TM/ETM images extracted the land use information and analyzed the land which were taken in 1992 and 2000 as main data, use changes in Tangshan with the assistance of GIS software based on the image classification. The results indicate, the land use of all districts in Tangs- han were in the period of development, and the land use change extent and speed were marked differently in space; arable land of Tangshan was decreased rapidly and the urbanization level of Tangshan was greatly improved. The decrease of arable land has great relativity with the increase of residential area/industrymining area.
