TY - Jour T1 - 遥感和土地利用GIS的综合方法和土地覆盖变更检测 - 以Madhya Pradesh，India Y1 - 2017-04-15 N2 - 土地利用和陆地覆盖的班尔河流域案例研究地区是目前评估流域和决策政策的发展策略的主要担忧之一。该国人口随着需求日益增长的情况下，对威胁到印度的发展中国家的土地对土地的巨大压力造成了巨大压力。The study was carried out to detect the land use and land cover changes observed in the Banjar River watershed lies in between Balaghat and Mandla districts of Madhya Pradesh, India using the multi spectral satellite dataset for two different years i.e. 2009 & 2013. The supervised classification was done in ERDAS IMAGINE software. The images of the study area was classified into seven classes namely, river, water body, waste land, habitation, forest, agriculture/other vegetation, open land/fallow land/barren land. The result indicates that during the last five years, forest, water body, waste land and open land/fallow land/barren has been increased by 2.26%, 0.55%, 0.23% and 0.48% respectively and the river, habitation and agriculture/other vegetation has been decreased by 0.26%, 0.04%, and 3.22% respectively. Accuracy assessment was also performed in this study to determine the quality of land use/cover map and overall accuracy was found 89.70% for 2009 and 91.91% for 2013.Present study emphasizes on digital change detection techniques for recognizing temporal changes in land use/land cover of the watershed. Outcomes of this study indicate need of implementing conservation and management practices for the socioeconomic development.
