At the same time, it inspected and recorded the gravel storage sites along the Gaoping River from time to time. It inspected 5 times until the end of June, purchased 2 satellite images and executed 8 aerial photographs. Follow-up on the basis of the map data and aerial photography results to handle 2 scenes of Gaoping River bare land survey operations, and indeed grasp the distribution of bare land along the Gaoping River. The bare areas of Gaoping Creek are mainly concentrated in the river sections of Dashu and Daliao District. There was 3 river dust incident in Kaohsiung City from July 2021 to June 2022.
The 7th River Management Office and Southern Region Water Resources Office also implements the dust improvement method on the bare ground of Gaoping River every year based on the bare land analysis data provided by this project to reduce the area of exposed riverbed and reduce the dust phenomenon of the Gaoping River. From January 2020 to June 2022, a total of 2,036.9 hectares of improvement related methods were implemented, such as: water cover method, mulch method, straw mat mulch, dredging works, sowing grass seeds and planting of Pennisetum. This project will discuss the next stage of the implementation focus through the action plan meeting. In addition, by cleaning up the surrounding environment along the coast to prevent road dust from being blown up, and to prevent the negative effects caused by river dust. During the implementation of this project, a total of 1,608.7 kilometers of environmental cleanup was completed. The reduction of TSP reached 22.2 metric tons and the reduction of PM10 reached 4.18 metric tons.
In 2021, this project will focus more on the promotion and improvement part, and realizes that the action should start with education. The promotion targets are divided into two parts as follows.

According to the division of rights and responsibilities, the goal of this project in 2021 is to reduce the number of dust incidents by 2 times and clean up the coastal road environment to reach 15,000 kilometers. According to statistics, the number of dust occurrences in 2021 is 0, and the environmental cleaning of coastal roads has been completed for 26,069.5 kilometers, which has reached the standard. the goal of this project in 2022 is to reduce the number of dust incidents by 3 times and clean up the coastal road environment to reach 15,000 kilometers. According to statistics, the number of dust occurrences in june 2022 is 3, and the environmental cleaning of coastal roads has been completed for 11,684.9 kilometers, still in line with the planning progress.(The target for the number of days of dust incidents is based on 8 occurrences in 2020, and is planned to decrease year by year).
