摘要
Researching the long-term and dynamics law of runoff has important scientific and practical significance for the sustainable using and planning the water resources. Studying the relationship between changes of vegetation cover and runoff dynamics is the basis for regulation of water resources. Vegetation regulation of runoff was affected by vegetation type, age, spatial distribution of coverage. Application of remote sensing (RS) and geographic information system (GIS) analyzes the changes of vegetation cover in watershed, and using the gray relationship analysis researches the relevancy of vegetation change and the runoff, and discusses the laws and mechanisms of vegetation cover affecting the runoff. Reliable results, but still facing many challenging scientific problems, theories and methods must be resolved.
