摘　　要：基于河北省曹妃甸地区1993、2007年获取的Landsat-5TM和ALOS卫星遥感数据，提取该区地表主要地质环境要素信息，分析其时空变化特征。结果表明：①湿地、非湿地农用地和居民及工矿用地的面积在1993年分别为32．3×10^4hm^2、20．6×10^4hm^2和4．21×10^4hm^2在2007年分别为27．7×10^4hm^2、21．8×10^4hm^2和6．8×10^4hm^2。14a间，湿地面积呈减少趋势，减幅为14．3％，其中稻田面积减少的绝对值居首位，为2．34×10^4hm^2；三角洲湿地面积减少的幅度最大，为77．3％；非湿地农用地和居民及工矿用地均呈增加趋势，增幅分别为5．6％和61，6％。②1993～2007年，海岸线发生较大变化，以大清河口的捞鱼尖为界，东部岸线表现为向陆侵进，最大侵进长度为500m；西部岸线表现为向海退缩，最大退缩长度为1000m。Taking Caofeidian area in Hebei Province as the study area and based on the remote sensing data of Landsat- 5 TM acquired in 1993 and ALOS acquired in 2007, the authors analyzed the temporal and spatial variations of surface geological environmental elements. Some conclusions have been reached ： （ 1 ） The areas of the delta wetland, agriculture land of non - wetland and residential and industrial land were 32.3 ×10^4hm^2,20.6 ×10^4hm^2 and 4.21×10^4hm^2 in 1993, and 27.7×10^4hm^2 ,21.8×10^4hm^2 and6.8 ×10^4hm^2 in2007, respectively. During the 14 years, the area of wetland decreased by 77.3% , while the agriculture land of non - wetland and residential and industrial land increased by 5.6% and 61.6% respectively. （2） From 1993 to 2007, the coastline varied obviously. The eastern coastline invaded the mainland with the largest invasive distance up to 500 m. On the contrary, the western coastline moved back to the sea with the largest retreated distance up to 1 000 m.
