Ecological landscape mapping is one of thematic types in cartography. Based on remote sensing, the ecological landscape information is extracted and classified in the middle reaches of Tarim River Basin. Moreover, landscape fragmentation, landscape evenness, landscape diversity and landscape dominance are 0.0035, 0.1856, 1.276 and 3.068 respectively. The river course and highway are main corridors in the area. Meanwhile, sand dunes and desert are matrixes which decide the ecological fragility in the area. Natural vegetation distributed far from the main course, which has improved the richness of landscape. Human activities are the main reasons for land partition and landscape fragmentation. Using remote sensing and relative techniques of Geographical Information Sciences, the ecological landscape can be understood thoroughly and systemically.
