摘要:
雄安新区的设立是千年大计、国家大事，地面沉降状况是关乎新区环境承载容量的重要因素。利用2012年1月至2016年11月获取的28期RADARSAT-2影像和时间序列InSAR技术，提取了雄安新区的平均沉降速率和累计沉降量，并用相近时段内的水准测量数据对InSAR监测结果进行了精度验证；对雄安新区地面沉降的原因进行了分析，并对雄安新区地面沉降危险性情况进行了评价。结果表明：雄安新区约78%的面积处于地面沉降轻微区（沉降速率小于每年10 mm），地面沉降危险性评价为较严重和严重的地区都集中在雄县，面积合计67.9 km2，占雄安新区面积的4.38%；雄县地面沉降主要是地热资源开采及塑料包装业采用地下水所致。研究结果对雄安新区的建设与发展具有参考价值。
Abstract:
The establishment of Xiong’an New Area is a millennium plan and a national strategy. Located in the North China plain, the largest subsiding zone of China, the ground subsidence condition of Xiong’an New Area is an important factor related to its environmental carrying capacity. The ground subsidence of Xiong’an New Area was monitored using time-series InSAR technique with 28 RADARSAT-2 images acquired from January 2012 to November 2016. The annual subsidence rate and the accumulative subsidence series over Xiong’an New Area were retrieved. The InSAR monitoring result was validated by leveling data measured over the similar period with the SAR image acquisitions. Subsequently, driving forces of ground subsidence over Xiong’an New Area was analyzed, and the land in Xiong’an New Area was categorized into 4 subsiding risk levels according to annual subsidence rate. The results show that about 78% of Xiong’an New Area had little ground subsidence with annual subsidence rate less than 10 mm per year, and the large subsidence occurred only in Xiongxian county which was mainly caused by extraction of geothermal resources and groundwater. There were 67.9 km2 with the subsiding risk categorized as relatively serious and serious levels, accounting to 4.38% of Xiong’an New Area. The result of this research could provide decision-making reference for the construction and development of Xiong’an New Area.
