Conteúdo:  The IBP Grassland Biome Program is a major ecosystem analysis involving 88 principal investigatigators systematically describing the functioning of natural grasslands. A compre- hensive remote sensing research program has been undertaken in the context of this ove- rall experiment to determine the utility of various sensor devices in supplying input data into this biosystem model. The initial objective of this effort has been to design and test a multi- faceted approach to measure and map percent cover of areas ranging from small grass- land plots to much larger landscapes. These maps provide the basic data from which to interpret standing crop or above ground biomass and in turn, the primary productivity of a grassland. The amount of vegetation on a prairie can be measured by its characteristics spectroradiance or spectroreflectance. A variety of approaches to exploiting this relation- ship are covered in the report, including the use of airborne and satellite multispectral sca- nner imagery, aerial and ground photography, and ground spectrometry. Each of these approaches is explained in detail and preliminary results are presented. A description of the design, construction, and testing of the trailer-mounted, field spectrophotometer is also included. A landscape model is described which has been designed to interface the data taken by mapping remote sensors to the biosystem or hydrologic models which statistica- lly describe the functioning of a natural grassland.
