摘要
基于遥感卫星影像数据及分析技术,以齐齐哈尔市境内的河湖岸带为研究对象,Landsat影像为数据源,采用NDVI像元二分模型,运用GIS叠加分析功能,分析齐齐哈尔市境内的河湖岸带植被覆盖度空间变化特征。结果表明,齐齐哈尔市境内河岸带植被覆盖度空间变化主要受地形和水文情势影响。本文研究成果及结论有助于剖析齐齐哈尔市境内河岸带生态问题,为岸线生态修复提供决策支持。
Based on remote sensing satellite image data and analysis technology,taking the riparian zone in Qiqihar city as the research object and Landsat image as the data source,using NDVI pixel dichotomy model and GIS overlay analysis function,this paper analyzes the spatial change characteristics of vegetation coverage in the riparian zone in Qiqihar city.The results show that the spatial change of vegetation coverage in the riparian zone in Qiqihar city is mainly affected by the terrain and hydrological situation.The research results and conclusions are helpful to analyze the ecological problems of the riparian zone in Qiqihar city and provide decision support for the ecological restoration of the riparian zone.
