| 英文摘要 | Qinghai-Tibet Plateau is an important part of global terrestrial ecosystem, and plays a significant role in regional sustainable development. The land cover classification in Qinghai-Tibet Plateau has been a topic research in recent years. Digital elevation model (DEM) have proved to be an effective aid to improving land cover classification. The objective of this study is to assess the contribution of incorporating DEM data in image classification to improve the spectral information accuracy. Two different bands combining methods, band I and band 3 of Moderate Resolution Imaging Spectrometer (MODIS), combining with Normalized Difference Vegetation Index (NDVI), band 1 and band 3 of MODIS, incorporating with NDVI and DEM, were used to classify the land cover of Shannon Prefecture. Results showed that the DEM data considerably improved the classification accuracy, the overall classification accuracy in test area improved 12.89%. As for most land cover types, the method combing DEM improved the classification accuracy at the same time, the producer accuracy of alpine meadow steppe and temperate steppe improved 23.06% and 27.03%, the user accuracy of cultivated land and alpine steppe improved 26.42% and 21.45%. |
