中文摘要:
      近年来广西地区滑坡坍塌灾害频频发生,威胁着人民生命和财产安全。为了给相关部门提供科学的滑坡监测数据以及提前制定合理有效的防治计划,本文以广西岑溪地区为例,利用干涉合成孔径雷达技术和岑溪地区2016年至2019年的20景哨兵-1A数据,提取了岑溪地区地表形变结果,结合地区历史降水数据综合评估了研究区内主要滑坡隐患和进行了形变时序分析。结果显示,岑溪地区的滑坡隐患主要分布在矿山采空区、公路沿线边坡、乡村山岭地带,其地表及边坡沉降多受生产建设等人为活动影响,加之广西地区重山复岭的山体地貌以及结构多变复杂的地质特点,在持续降雨的影响下加速下沉;此外,随着产业转移和地区经济的快速发展,区域内矿山、城乡公路沿线及边坡的沉降呈逐渐增强和扩大趋势。该案例可为岑溪地区的防灾减灾提供有力的数据与技术支持,并为丘陵山区的滑坡灾害隐患与形变分析提供思路与参考,也证明了干涉合成孔径雷达作为新兴雷达遥感测量手段,可以高效准确地对丘陵区域进行滑坡灾害隐患识别。
英文摘要:
      In recent years, landslide disasters in Guangxi have increased, threatening people's safety.In order to provide relevant departments with scientific landslide monitoring data to formulate a reasonable and effective prevention plan,this article takes the Cenxi area of Guangxi as an example, the surface deformation was extracted using InSAR technology and the Sentry-1A data from 2016 to 2019 in the Cenxi area. Combined with precipitation data, the main landslide hazards were evaluated and the deformation time series analysis was carried out. The results show that the landslides in Cenxi area are mainly distributed in mine goafs, highway slopes, and country mountains, and the slope settlement is mostly affected by human activities. The complex geology of Guangxi and the impact of rainfall are also the reasons for the sinking. With the industrial transfer and the rapid development of the regional economy, the settlement of mines, urban and rural roads and slopes in the region has gradually increased and expanded.
