| 摘 要： | 通过NetWeaver设计模糊知识库，利用EMDS模型定量评价了岷江上游1986--2000年景观变化．结果表明：整个流域景观的斑块类型、面积、数量及空间配置均发生了较大变化，且朝着有利于生态恢复的方向变化．森林类型的变化主要发生在北部（松潘县和黑水县）．草地类型的变化主要发生在北部（松潘县）和最南部（汶川县）．流域景观变化是人类活动强度增大和自然变化共同作用的结果．

| Abstract: | 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. |
