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.
