Subsidence of the stratum is a global problem, which has great damage to water and soil resources, especially in the face of global climate change and warming today, which highlights the seriousness of the problem. The problem of stratum subsidence in Taiwan has been around for a long time. First, in Taipei City in the 1950s and 1960s, the subsidence amounted to 2.5 meters. Fortunately, the relevant water resources were properly planned and controlled, and the subsidence was controlled. However, the migration of aquaculture fisheries and related water-consuming industries in the southwest coast in the past one to two decades has caused a widespread subsidence in the coastal area of ​​Pingtung in Zichanghua. As far as the subsidence rate is concerned, the rate of subsidence is currently 11.6 cm/year in the inland area of ​​Yunlin. Serious (Institute of Energy and Resources of the Industrial Technology Research Institute, Republic of China, 1994), so every torrential rain and typhoon, the accumulation of water is always a serious social and economic problem. Because stratum subsidence poses a serious threat to people's lives and property, the safety of public works, and the sustainable development of land and resources, and its prevention and control cannot be achieved overnight. Therefore, in the continuous promotion of prevention and control work, it is very important to establish a normal monitoring system. In addition to understanding the prevention and treatment effects of stratum subsidence, if you can further analyze the results of monitoring information and take timely warning measures for stratum subsidence, you can better understand Gradually to stop the continuous deterioration of the stratum subsidence.
