Abstract:: Using remote sensing images of Huairou Reservoir Watershed of Beijing in 1990, 1995 and 2000, with the help of ArcView, the change of spatial pattern of protection forest was obtained. At the same time, using the data of daily runoff of Huairou Reservoir Watershed in 1990-2006, the response relation between the change of the structure of protection forest and the local runoff was studied. The results showed that: the total area of protection forest had not changed obviously, but there were significant changes in the areas of various kinds of forest, from dominated by shrub to dominated by highwood. On the basis of the little change of the precipitation, the annual runoff had a tendency to reduce, the main reasons were the changes of the pattern of protection forest and the constant perfection of shelter-forest system. With the functions of protection forest played, after the year of 2000, the runoff decreased to 5% of the 1990’s, the runoff decreased year by year and had a steady trend.
