辽宁省盘锦市具有丰富的石油、天然气、煤等矿产资源，由于油气开发及南部沿海区域因海水入侵地下水开采持续增长等影响，导致该地区地面沉降明显。为掌握和分析该市地表形变的变化特征，本文利用2007~2011年间22景L波段的ALOS/PALSAR数据，采用PS-InSAR技术对其进行了地面沉降监测。从得到的年沉降速率图和沉降中心的时间序列图可知，盘锦市地面沉降主要分布在城镇、油田开采区以及沿海区域。四年间，最大年沉降速率达194mm/a，经调查发现主要是因该区域油气开采所致；沿海地区的年沉降速率约为50mm/a。研究表明，盘锦地区的地面沉降与油气开采存在空间一致性，同时也证明PS-InSAR技术可用于长时间序列的地面沉降监测。
遼寧省盤錦市具有豐富的石油、天然氣、煤等礦產資源，由于油氣開髮及南部沿海區域因海水入侵地下水開採持續增長等影響，導緻該地區地麵沉降明顯。為掌握和分析該市地錶形變的變化特徵，本文利用2007~2011年間22景L波段的ALOS/PALSAR數據，採用PS-InSAR技術對其進行瞭地麵沉降鑑測。從得到的年沉降速率圖和沉降中心的時間序列圖可知，盤錦市地麵沉降主要分佈在城鎮、油田開採區以及沿海區域。四年間，最大年沉降速率達194mm/a，經調查髮現主要是因該區域油氣開採所緻；沿海地區的年沉降速率約為50mm/a。研究錶明，盤錦地區的地麵沉降與油氣開採存在空間一緻性，同時也證明PS-InSAR技術可用于長時間序列的地麵沉降鑑測。

Panjin is located in the southwest of Liaoning Province and possesses abundant oil, natural gas, coal, and other mineral resources underground. Land subsidence has already occurred in the Panjin region due to oil and gas exploration together with water erosion. To monitor this ground deformation, permanent scatterer interferometric synthetic aperture radar （PS-InSAR） was used to process 22 L-band ALOS/PALSAR images obtained between 2007 and 2011. The average annual subsidence rates and time series for the region show that subsidence is mainly located in the cities and towns, oil ifeld exploration areas, and coastal areas. Maximum subsidence rates reached 194 mm/year over this four-year period, mainly because of oil exploration, while the deformation in the coastal area was only about 50 mm/year. The results obtained from the PS-InSAR analysis are in good spatial agreement with the underground extent of the oil ifeld, and also prove that the PS-InSAR technique can be used for ground subsidence monitoring over long periods.
