Abstract:: In order to explore the change and its causes of land-use landscape pattern characteristics in Wuyu’er River Basin, by using 1995 and 2000 TM images for basic information in the typical watershed Wuyu’er River Basin in Heilongjiang Province, and 3S technology and Fragstats software, the new changes of land-use and landscape pattern in Wuyu’er River Basin was studied and landscape index quantitative analysis was carried out from the level of patch type and landscape pattern. The main land use of landscape for Wuyu’er River Basin is cultivated land, and there is an increasing trend on the area of cultivated land. In the level of landscape types, the fragmentation index grasslands, waters and land for construction showed the slight decrease or in performance of flat, landscape fragmentation index increased of arable land, forest land and unused land, in particular the large increase of the index of arable land. In the level of landscape pattern, the main trend rate of change adverse the entire basin ecosystem function, and the ecological system vulnerability are increasing. The results can provide reflection for Wuyu’er River Basin in aspect of land-use planning and reasonable utilization and ecological landscape design.
