[Landscape change in upper reaches of Minjiang River].
Based on the fuzzy logic knowledge database designed by NetWeaver tools, and using ecosystem management decision support system (EMDS), a quantitative evaluation was made on the landscape change in the upper reaches of Minjiang River from 1986 to 2000. The results showed that the type, area, amount, and spatial distribution of landscape patches in the reaches changed greatly, and the changing direction was in favor of ecosystem restoration. The changes of forest landscape mainly occurred in the north part of study area (Songpan County and Heishui County), while those of grass landscape mainly occurred both in the north part and in the furthest south part (Wenchuan County). The joint effect of increasing human activities and nature change was the driving force of the landscape changes.
