The problem of stratum subsidence in Taiwan is mainly related to the unbalanced development of groundwater resources. First, the rapid urban development of the Taipei Basin in the 1950s and 1960s caused a large amount of over-pumped groundwater, which resulted in serious stratum subsidence. The relevant units carried out water resources development and groundwater. With proper control, the stratum subsidence can be controlled. However, due to the development of water-consuming industries in the southwestern coastal areas, severe stratum subsidence also occurred in the south of Changhua to Pingtung.。

As of 2004, the largest cumulative total subsidence was in Pingtung Yanfeng at 3.22 meters (from 1972 to 2004). The subsidence rate was the most significant in Xihu Town, Changhua County. The maximum annual subsidence rate was 14.2 cm, followed by In the Baozhong and Yuanchang areas of Yunlin County, the maximum annual subsidence rate is 10.4 cm. There are many methods for monitoring and investigating stratum subsidence, including stratum subsidence monitoring wells, leveling measurement, and the application of satellite technology. The occurrence and process of stratum subsidence can be monitored from different angles. Among them, the setting of stratum subsidence monitoring wells is mainly used to monitor the compression behavior and characteristics of the stratum. The discussion of the subsidence mechanism can provide the most direct verification data and can also play the role of early warning.

The establishment of the stratum subsidence monitoring well network was mainly coordinated with the implementation of the "Taiwan Area Groundwater Observation Station Network Project" and the "stratum subsidence prevention and control implementation plan" after 1994. It was planned by the Water Resources Department of the Ministry of Economic Affairs at that time (later restructured into the Water Resources Bureau) , And set up in the severely subsided area of ​​the southwest coast of Taiwan. Later, the Water Resources Department of the Ministry of Economic Affairs continued to promote the second phase of the stratum subsidence prevention and control plan, and continued to add stratum subsidence monitoring wells in the new stratum subsidence area and the stratum subsidence potential area to monitor the formation caused by pumping water The compression behavior of different depths.
