| Abstract: | The Guanting Reservoirwill be the second water resources of Beijing for drinking, but the alluvial problem
has been puzzling for decades. The paper studied the shoreline dynamic evolution of the GuantingReservoir from1988 to
2001 using change detection technique, with multitemporal Landsat TM data(1988, 1994, 2001). After geocorrecting
and radiometric normalization, principal component analysis and global change detection methodwas used. Several prob-
lems, such as reservoir silting, shoreline types etc.,have been discussed.
The remotely sensed temporal and spatial analytic method to shoreline slope and shoreline stability discriminant have
been presented, according to the relationship of proportion between thewidth of change detections and difference ofwater
level on shoreline. With this method, shorelines were chassified to 3 types, alluvial, erosive, as well as balance shore-
line. The affects of the above-mentioned factors to thewater resources in the Reservoir have been analyzed. The shoreline
stability discriminant will be applicable potentially on the low-lying beach areas of ocean and lake, andgle between
