基于知识的厦门市生态环境遥感系列制图

本文利用厦门市2001年3月的LANDSAT TM／ETM+图像为主要信息源,在拟订生态环境要素:地质、地貌、土壤、植被、土地利用等的分类系统和编码基础上,确定了厦门市生态环境遥感综合系列制图的内容,进行了遥感影像的解译。讨论了系列制图的方法与步骤,轮廓界线的确定和地图综合过程,同时阐述了厦门市生态环境遥感综合系列制图的软件。

Study on the Making of 1:100000 Serial Integrated Remote Sensing Maps on Eco-environment in Xiamen City

This paper firstly introduces the general condition and characteristics of the regional environment.Then it identifies the classification systems on ecological elements composed of environmental landscapes, such as geology, landform, soil, vegetation, etc. Based on these and two satellite images from Landsat TM/ETM+ in March,2001 in Xiamen city, the contents of the study on the serial integrated remote sensing mapping of eco environment in Xiamen city are defined. Its theoretical foundation, in fact, is a methodology of map deduction which is analyzed and discussed. Its cores or key contents are the synthesis based on the analysis and in the meantime on the analysis under the guidance of the synthesis. After the identified symbols of image interpretation are established, the remote sensing images are interpreted through the naked eyes and the results are corrected by field investigations. The paper further discusses the methods and steps, including confirmation of the outlines of the map and the methods of cartographic generalization, etc. Finally, the detailed processes are described on how to use GIS ArcView software to make the serial integrated remote sensing maps at a scale of 1:100 000 on Xiamen eco-environment, and the latest development tendencies and the view of new century of cartography are also briefly outlined.
