The paper synthesized the remote sensing data obtained by Landsat series satellite(MSS,TM,ETM+) to survey and assess the land utilization,development of vegetated land,non-vegetated land and water area in Daya Bay district from 1979 to 2004.According to the data derived from Landsat in the past two decades the vegetated area around the Daya Bay remained stable while the non-vegetated land rose from 5.1% in 1991 to 10.5% in 2004 and the water area decreased by about 5% correspondingly.It showed a pattern of "human expansion,water retraction" which was highly related with the environmental and economic development in Daya Bay district.By building the relationship between the mode of human's impact on regional environment,we can predict the impact of developmental action on land utilization and apply it to regional EIA.The study demonstrates that remote sensing can be applied as an effective tool for monitoring the changes of coastal land utilization.
