摘要
介绍了InSAR技术湿地水位监测原理,分析了影响InSAR湿地监测结果精度的因素。以江苏盐城射阳县的湿地为实验区,研究了InSAR监测湿地水位变化的可行性。结果表明,InSAR技术能大范围监测湿地水位变化情况,且水位变化监测结果与实际情况相符,表明利用InSAR技术监测湿地水位变化是可行的。
The principle of wetland InSAR was described in this paper. And the factors, affecting the accuracy of detecting results, were analyzed. And then, taking the wetlands, locating in Yancheng of Jiangsu Province, as the experimental area, the feasibility of wetland water level change detection was investigated using InSAR technique. The results show that large-scale water level change of wetlands can be detected by InSAR technique. The wetland water level change obtained by InSAR is consistent with the actual situation. Wetland water level change detection using InSAR is feasible.
