Using Fragstats 3.3 and interpreted results of remote sensing images in Banchengzi Reservoir watershed in 2000 and 2005, changes of forest landscape pattern is obtained. Results showed that forest land is the matrix of Banchengzi Reservoir watershed from 2000 to 2005. Dominant index of coniferous and broad-leaved and mixed forest is higher than other landscape elements. The area of the patches is distributed unevenly. In landscape heterogeneity aspect, the heterogeneity of coniferous forest is increased; patch complexity of forest is higher than other landscape types; patch quantity of landscape elements is enhanced; and landscape elements are distributed more evenly. In spatial inter-correlation aspect, landscape fragmentation is increased and whole spatial aggregation of landscape level is reduced.
