A sustainable land use information system

摘要

Soil moisture plays a major role in atmospheric and hydrological processes, since it influences the partitioning of both surface available energy into sensible and latent heat fluxes, and of precipitation into evapotranspiration and runoff. Soil moisture is also an important parameter for ecologial processes, for instance, the availability of soil water directly affects plant growth. For studies of plant growth and land use sustainability, there is na increasing demand for detailed predictions of soil moisture over large areas.
