Discussion on studying biodiversity by remote sensing

Remote sensing for biodiversity study has the advantage of the total coverage of extended area that includes the investigation regions and their peripheries, which assures easy assessment of structural parameters in a synoptic way and visualization of the studied area. Remote sensing can provide various useful data at different scales. However, a comprehensive assessment of biodiversity not only needs data from remote sensing, but from other biological, ecological and socio_economic information. Therefore, it is necessary to establish a biodiversity information system under the framework of geographical information system(GIS), which have the required special functions and contents. To extract knowledge from these data, theoretically rational mathematical models are necessary. In general, the combination of remote sensing data with GIS and mathematical models is an essential foundation for obtaining ideal results, which can be used to quantitatively assess biodiversity, ecologically preserve biodiversity and economically utilize biodiversity.
