Abstract: Based on the high resolution IKONOS data, remote sensing(RS) and geographic information system(GIS) were used to study the characteristics and its influential factors of landscape pattern in the hilly region of the central Sichuan basin. The results indicate that, with the relief increment and the reduction of human activities, the diversity index in the low hill, middle hill and high hill is 1.1437, 1.3598 and 1.4367, respectively;the dominance is 0.8022, 0.5861 and 0.5092, respectively;the fractal dimension is 1.2652, 1.3019 and 1.3272, respectively;the degree of fragmentation is 23.9488, 30.1556 and 24.4666, respectively. Therefore, landscape pattern in the hilly region of the central Sichuan basin is mainly controlled and influenced by climate, relief, gradient, human activities and the distribution of residential areas.
