This paper obtained the data of land use change based on the TM images interpreted in 1980,1995 and 2005 taking Suzhou as a case study.First,this paper analyzed the characteristics of land use change during 1980-1995 and 1995-2005.Then,eco-environmental quality was associated with land use types according to the relative ecological service value of different land use types.The effect of land use change on the eco-environmental quality was measured and quantified by calculating the regional eco-environmental indices.The major land use transformation types causing the change of eco-environmental quality were found out by calculating the contribution proportions of land use transformation types to eco-environmental quality.The regional eco-environmental quality index decreased from 0.4609 to 0.4431 in Suzhou from 1980 to 2005,which reflected that the eco-environmental quality was continually decreasing; and the rate was faster and faster.In the study phases,the transformation from arable land to constructive land was the major land use transformation type deteriorating the eco-environmental quality; the transformation from arable land to water area was the major land use transformation type improving the eco-environmental quality.
