黑河流域2019-2020年地表形变InSAR监测与生态响应分析
InSAR monitoring and ecological response analysis of surface deformation in Heihe River Basin from 2019 to 2020
摘要
Abstract
[Objective]The Heihe River Basin(HRB)is the second-largest inland river basin in the arid to semi-arid region of northwest China.Existing studies have mostly focused on its ecological environment,while research on surface deformation related to groundwater extraction for dryland agriculture and mineral resource exploitation remains insufficient.[Methods]In response to the need for surface stability monitoring in the HRB,an improved IPTA-InSAR technique was employed to process a total of 101 Sentinel-1 SAR images from two orbital tracks covering the study area from 2019 to 2020,generating a time series of surface deformation.The reliability of the result was verified using independently processed data from overlapping adjacent tracks.Furthermore,high-resolution optical remote sensing data were integrated to comprehensively analyze deformation characteristics.[Results]The result showed that the root mean square error between adjacent track result was 0.2 mm/year,and six significant deformation zones were identified within the basin.The maximum annual average subsidence rate reached 56 mm/year,and the maximum seasonal subsidence and uplift along the satellite line of sight were-70 mm and 60 mm,respectively.[Conclusion]The spatiotemporal distribution characteristics indicate significant heterogeneity in deformation mechanisms:(1)periodic subsidence due to seasonal over-extraction of groundwater in midstream oasis irrigation areas;(2)seasonal rebound influenced by groundwater rise during the rainy season in the saline-alkali lands along the Great Wall in eastern Jiuquan;and(3)continuous subsidence caused by mining activities in the Jinchang open-pit mine and Shandan coal mining areas.The findings of this study can provide a scientific basis for the optimized allocation of water resources in river basins,dynamic regulation of mining operations in mining areas,and protection of ecologically vulnerable zones,and offer important references for the coordinated development of human-land systems in the inland river basins of Northwest China.关键词
