主 题：Dry lands rangelands biomass remote sensing monitoring
摘 要：The paper describes the capabilities and opportunities of Remote Sensing and GIS technologies for monitoring the rangeland vegetation and its dynamics under different type of factors. Potential of satellite data of Landsat 7 Enhanced Thematic Mapper Plus （ETM＋） Imagery for monitoring the rangeland condition of Karnabchul semi desert was exemined. The paper presents the first stage of a method for vegetation assessment of rangelands based on spectral vegetation indices such as Normalized Difference Vegetation Index （NDVI） derived from remotely sensed data. Initial results of the research showed the Landsat satellite images can provide relevant information about current condition of rangeland vegetation. It is recommended to conduct further studies using remotely sensed data for improvement of the rangeland monitoring methods.
