Abstract

Human activities are important factors leading to the change of regional land utilization/coverage. In order to reveal the influence of human activities on the oasis landscape ecosystem in arid area, in this article, the various landscapes of human acting regions in 2000 and 2005 were compared and analyzed for Xinjiang Manas County of West-China using remotely sensed data, which showed that there is a great increasing tendency in farmland and urban landscape area, however, a dramatically decreasing tendency in forest and grass areas and patch numbers. Meanwhile, the internal structure of forest and grass landscape also changes greatly. The main driving factors of this change are agricultural technology and innovation of agricultural organization system, which strengthen the replacement of forest and grass landscape by farmland. And at the same time, the quality and areas of some forests and grassland loom optimizing tendency with the policy of "change the farmland back to forest and grassland" implemented and ecological protecting forest constructed.
