摘要
凌河口湿地位于辽宁省境内,与双台子河口湿地相邻,是辽宁省一个比较重要的河口湿地,不仅具有重要的生态和科学研究价值,而且具有巨大的经济价值。本研究综合利用GPS、RS、GIS技术,采用目视解译法对研究区2000年和2005年的遥感图像进行了解译,实现了湿地识别、类型划分、面积值计算等功能,初步建立了凌河口湿地信息系统。
The estuarine wetland of Linghe River is located in Liaoning Province and is adjacent to the estuarine wetland of Shuangtaizihe River; which is a more important estaarine wetland that not only has important values for ecological and scientific researches, but also has great economic values conceIlaed. Based on the comprehensive application of the technologies of GPS, RS and GIS, the remote sensing images of 2000 and 2005 within the study area are visually interpreted, and then the functions of identification, classification, area calculation, etc. for wetland are realized along with the preliminary establishment of an information system of this wetland.
