唐山城市用地现状遥感调查方法

Investigation for Tangshan urban land use situation based on remote sensing method

为查清唐山市中心城区的用地类型及现状分布,发现城区用地存在问题,采用高分辨率遥感影像为主要数据源,Arc GIS为内业数据处理与分析工具,研究了基于RS与GIS的唐山市城市用地现状调查研究的过程,详细论述了地类解译、外业调绘过程以及数据库的建立方法,制作了土地利用现状图并对统计数据进行了探讨.研究结果表明:RS结合GIS应用于土地利用现状调查具有快速、经济、实用的特点,基于此方法得出的数据可为唐山市中心区国土资源规划提供依据.

In order to investigate the type and the distribution status of Tangshan urban land use, and find some existing problems, this paper utilized the high-resolution remote sensing image as the main data source and ArcGIS as the internal business processing and analysis tools, researched the process of investigation for Tangshan current land use situation based on RS and GIS method, and discussed the detailed method of land type interpretation, field annotation process as well as the database creation. The current land use map was created and the statistical data was further discussed. The research shows that RS combined with GIS applied to the Investigation of land use is rapid, economic and practical, and the data obtained with this method can provide a basis for planning land resources in Tangshan downtown area.
