Abstract:

Danjiangkou Reservoir is the water source of the middle route of “south to north water transfer project”，so land use/cover change of the reservoir area may result in ecological and environment problems which have attracted great attention.Based on the 2000 and 2004 multisource remote sensing image， the land use/cover classification is built by interpretating the data.Then the overall characteristics of land use/cover change and the variation speed，the change of the index of landscape dominance and landscape effects were also analyzed in the study area.It is showed that the area of farmland and land for building increased，the forest land and the unused land reduced；the landscape heterogeneity declined，and the landscape types showed a trend towards a singlebalanced direction.The decrease of the forest land deteriorated soil erosion,so that the ecological environment of the reservoir area is worse and some steps should be taken to promote the harmonious development between the economy and the environment.

Key words: Danjiangkou Reservoir Area, remote sensing image, land use/cover change (LUCC), landscape pattern〖
