Abstract: Regional land use and land cover change is an important part of global change.Based on the land cover data in 1986,1996 and 2001,and employing ARC/INFO software and landscape ecology method,this paper studied the past 15 years' land use and landscape pattern changes (LULPC) in coastline buffer zone (3 km) of Bohai Sea,with the affect degree and scope analyzed.The results showed that spatially,the land use degree comprehensive index (Y) of Bohai Sea coastline buffer zone in 1986 and 2001 increased with the distance to Bohai Sea coastline (X),with the linear correlation equations Y86=7.728X+96.584,R=0.979**,and Y01=19.156X+112.2,R=0.983**.While in 1996,the index did not change dramatically.Temporally,the index increased from 1986 to 1996,as well as from 1996 to 2001.Other landscape pattern indexes except dominance index had no significant correlation with the distance to the Bohai coastline.
