Abstract The middle Shiyang River valley with a sensitive ecological environment was chosen as the study area. First of all,
land use/land cover information was extracted by using multi-temporal and multi-source remote sensing image. Then the landscape
change tendency, change area, change rate and specific conversion type were studied quantitatively through the transfer matrix
calculation. Through extracting characteristics of landscape pattern indexes, the regional pattern of landscape ecology and
landscape heterogeneity were analyzed. Finally, the driving factors for landscape pattern change were investigated. This study is
likely to deepen the scientific understanding of the ecological environment in the middle Shiyang River valley and can promote
the comprehensive management of Shiyang River Basin, thus having both scientific significance and practical significance.
