Abstract: Based on the TM images in 1984 and 2002, and with the application of GIS and RS, this paper studied the landscape dynamic variation of Wuzhong district of Suzhou City. Using the means of stepwise regression, the human driving forces were analyzed.The results showed that the regional landscape pattern has changed dramatically, especially from cultivated land to water area, and to urban land and other construction areas. The decrease of cultivated land occupied 79.3% of total decrement,while the increase of the construction and water areas accounted for 63.5%,36.5% of the total increment, respectively. The patch area of human landscape such as land for towns and industries has been increasing, and their patches have been congregating. The ragmentation of natural and seminature landscapes such as cultivated land and woodland has increased, and their patches have been separating. The shape of cultivated and urban land has become more complex. The regional landscape diversity has increased because of the cultivated land dominance reduction. Because of the location and topography, the intense loss of cultivated land takes place around Suzhou City and in the eastern plain, and the distribution centroid of cultivated land patches has moved 4.74 km towards southwast in the last eighteen years. The human driving factors for landscape spatial change are the rapid growth of population, fundamental construction investment, foreign investment and development of the tertiary industry which were based on tourist industry.

Key words: landscape pattern, dynamic variation, human driving factor, around Tai Lake
