摘要

This entire issue is dedicated to an ambitious modeling effort put together by Guest Associate Editors Stephen D. Pre ston and David M. Wolock, along with Associate Editor Richard B. Alexander. SPARROW - SPAtially Referenced Regres sions On Watershed attributes - is a hybrid empirical/process-based mass-balance model that can be used to estimate the major sources and environmental factors that affect the long-term supply, transport, and fate of contaminants in streams. Other major models such as SWAT and MODFLOW have adapted successfully to the GIS age, but SPARROW is perhaps the first to be developed originally using GIS technology and geospatial data. The spatially explicit model structure is de fined by a river reach network coupled with contributing catchments.
