Abstract Based on the remote sensing data in 2005,the general features of land use type and landscape patterns in Changwu County,Shaanxi Province,in the Loess Plateau were studied with the methodologies of remote sensing,geographical information system（GIS）and the landscape ecology.It is shown that: the matrix landscape in this area was garden plot and woodland,which were embedded by other landscape patches.The current landscape pattern in the study area illustrated its landscape features as low biodiversity,high distribution evenness,low level of heterogeneity and low fragmentation and fractal dimension of the overall landscape in this area.It was learned from the patch area and the patch density that the fragmentation of farmland and garden plot is high,but it is low in the woodland. The results also showed that there was obviously negative correlation between the area of the garden plot and the woodland and there was obviously positive correlation between the dominance and the contagion.The results demonstrated that Penggong village had mainly high level of dominance and contagion and low level of fractal dimension dominated by large blocks of garden plot and woodland.
