摘要

One of the emerging areas of scientific interest in the control of non-point-source pollution (NPS) is the detection and analysis of impervious surfaces within watersheds. NPS runoff from urban surfaces is now a leading threat to water quality and the percentages of impervious surface within a particular watershed has been recognized as a key indicator of the effects of non-point runoff and of future water and ecosystem quality. Although the effect of land use, population and impervious surface cover on water quality has been generally known for thirty years, a basic problem exists in quantifying the detailed spatial extent and distribution o various classes of impervious surface phenomena.
