Abstract:: Majiang County of Guizhou Province was taken as the study area. This paper analyzed the change of woodland landscape in topographic gradient by using the theory and method of landscape ecology from 1992 to 2012.The results showed that: (1) CA, NP, PD, PLAND, AREA-MN and LSI of woodland changed with the slope and altitudinal gradient zone changed during the study period; landscape fragmentation of woodland reduced and landscape pattern became simpler at high altitude and steep slope areas, landscape fragmentation of woodland increased and landscape pattern became complex at low altitude and gentle slope areas; (2) COHESION and AI showed a downward trend at low altitude and gentle slope areas, while SPILT showed the upward trend, which reflected that landscape distribution of woodland tended to scattered and the aggregation and connectivity tended to decrease, COHESION and AI showed the upward trend at high altitude and steep slope areas, while SPILT showed the downward trend, which reflected that landscape distribution of woodland tended to concentrate and the aggregation and connectivity tended to increase.
