Abstract：To fully grasp the nature and human geography situation information and solve the problem of ecological environment, economic and social development of China, it is of great significance to monitor the resource and environment indexes. The authors studied the spatial and temporal distribution of resources and environment in Haidian District of Beijing from 1986 to 2010 with Landsat TM images. Meanwhile, the driving forces were analyzed. The results show that, from 1986 to 2010, farmland decreased by 45.7%, build-up land increased by 38.95%, forest and grass land increasd by 23.44%, and water and other land kept constant. Urban area extended westward and northward, especially in Xibeiwang area. The mass center of Haidian also moved to the northwest. The urban compactness decreased and the fractal index increased gradually, indicating that the city saturation degree was reduced, and the city boundary became complicated gradually. The comprehensive land use dynamic degree first decreased and then increased. Population growth, economic development, infrastructure construction and the formulation of policies and regulations all contributed to the changes of resources and environment.
