| 摘 要： | 以崇明东滩这一河口潮滩湿地为研究对象,利用ERDASIMAGINE图像处理软件,结合地面景观类型调查,对其1988年和2002年的SPOT遥感数据进行监督分类;对监督分类结果进行人机交互目视解译纠正,得到精度较高的崇明岛东部海岸带的景观图,并可此基础上进一步进行各种景观特征的定量分析和景观变化研究。最后讨论了不同研究目的对景观分类精度的要求,以及所采用信息源的分辨率能够划分至最细的景观要素类型。

| Abstract: | The landscape of Chongming Dongtan, a typical area of estuarine tidal flat wetland, was made a supervised classification by using ERDAS IMAGINE software and minimum distance rule, combined with a survey to the landscape types of this area. The result of supervised classification in 1988 and 2002 was modified through the method of Man-machine Interactive Interpreting and attained landscape classification map of relatively high precision. On this basis, the quantitative analysis of landscape features and research on landscape change could be done. Lastly, this paper discussed the demand for the pricision of landscape elements classification catering for different research purposes, as well as the maximum capacity of identifying the finest landscape types from the data source. |
