摘要
采用地形图对比法、精密水准观测法和合成孔径雷达干涉测量技术（InSAR解译法）,研究不同时段盘锦湿地的地面沉降历史和现状。结果表明,盘锦湿地泵站作废和灌渠无法正常引水等是地面沉降所致。1956～1984年,盘锦湿地地面最大平均沉降速率为3.21 mm/a,沉降程度低,处于稳定阶段;1982～1994年,盘锦湿地地面最大平均沉降速率为10.41 mm/a,沉降程度较低;1994年以后,盘锦湿地地面最大平均沉降速率远超过80mm/a,局部地区最大平均沉降速率达到240 mm/a,地面沉降程度很高,破坏了湿地环境。
The subsidence history and current situation of Panjin wetlands in different periods were studied by topographic map comparison, precision leveling and synthetic aperture radar interferometry（In SAR） methods.The results showed that the land subsidence in Panjin wetlands caused the pump station to be abandoned and the water diversion can not be normal. From 1956 to 1984, the maximum sedimentation rate of Panjin wetlands was 3.21 mm/yr, with a low degree of subsidence and a stable stage. From 1982 to 1994, the maximum settlement rate of Panjin wetlands was 10.41 mm/yr. After 1994, the maximum subsidence rate of Panjin wetlands was more than 80 mm/yr, the maximum land subsidence rate was 240 mm/yr in partial area. The land subsidence destroyed wetland environment and affected the local economic development.
