%X The research on land use and land cover changes is a core for studies on the global change. The study on spatial pattern and its change of land use is important for better understanding land use/land cover changes and environmenta l management. Remote sensing and geographical information system were used to an alyze the landscape pattern and its driving factors of land use in China. First, the types of land use in China were divided into six major types and twenty-si x sub-types. The major types include cultivated land, forestland, grassland, wat e r area, built-up land and barer land. Second, the information of land use class i fication was extracted from a database of resource and environmental with 1:1000 00 scales and in raster format. The spatial pattern of land use based on the lan d use classification database was analyzed. Third, we calculated the landscape d iversity index(H), the landscape dominant index(D), the landscape homoge neity in dex(E) and the landscape broken index(C).These indexes of spatial patter ns showe d a clear picture of disturbance caused by human activities. With the increasing of disturbances, the diversity index, the homogeneity index and the broken inde x all increased and the dominant index decreased. However, when natural landscap e was transformed completely by human activities, shown as the increased human i mpact, the diversity index, the homogeneity index and the broken index all decre ased and the dominant index increased. Fourth, According to characteristic of la ndscape patterns and its eco-environmental background of land use, five transec t s were selected and the driving factors of land use landscape patterns were anal yzed.
