中文摘要	本計畫執行期自109年5月18日起至110年5月17日止，各項工作皆已完成(詳表1)，並依規定於110年4月27日前提交期末報告初稿送審，於110年6月15日收到審查意見後，於6月30日將委員意見回覆同意修正提送貴局審核。以下即為各項工作執行成果摘要：本計畫橫向結合其他計畫之UAV空拍能量，滾動式掌握裸露地分佈現況，推動河川管理單位以超前部署的概念，提早完成裸露地改善作業，統計109年(1~12月)共改善651.2公頃裸露地，較108年提升8%，為近5年裸露地改善面積最高，另依據工法抑制期程分析可削減16.73公噸之PM10。此外，也透過辦理跨局處之「濁水溪河川揚塵改善成果參訪觀摩」，邀請水利署第七河川局共同參與，藉此汲取濁水溪河川揚塵改善之經驗，進行高屏溪河川揚塵改善工法之發想，並於「高屏溪河川揚塵防制聯繫會議」共擬「高屏溪揚塵改善作戰策略圖」，以因地制宜及因時制宜的裸露地改善概念，新增不受地形侷限之UAV植保機撒草籽工法，以及怪手灑水之緊急應變能量，強化防制河川揚塵能量。統計109年3次河川揚塵事件日最高PM10最大小時平均濃度為440.3 μg/m3，比對108年河川揚塵事件日最高PM10平均濃度為601.7 μg/m3，其PM10最大小時平均濃度降低約27%，另110年依據環保署3次河川揚塵預警資訊(5月4日、5月14日、5月15日)，進行6次滾動式ISCST3之PM10增量模擬作業，並比對UAV空拍資料，分析可能造成河川揚塵事件之關鍵性裸露地，並將相關資訊協請河川管理單位進行預防性揚塵抑制作業，以減少河川揚塵影響濃度或發生機率。統計110年1~5月17日並無高屏溪河川揚塵事件發生，亦優於106~109年同期情況。在環境清理方面，本計畫共執行3,057.8公里河川揚塵環境清理作業，推估PM10削減量為7.9公噸。在教育宣導會議的辦理方面，本年度共辦理1場次沿岸河川揚塵教育訓練、3場次學校河川揚塵教育宣導活動及1場次高屏溪河川揚塵預通報及自我防護演練作業。透過教育宣導活動後之問卷調查，有95%之受訪者對於環保局推動河川揚塵相關業務給予正面的評價，另環保局委外之問卷調查結果，受訪民眾對於本縣河川揚塵改善給予89%的正面評價，與本計畫之問調結果相呼應，而針對環保署之河川揚塵改善考評項目，達成率則為100%。

摘要	The implementation period of this project is from May 18, 2020 to May 17, 2021. All work items have been accomplished and the first draft of term report was submitted by April 27, 2021 in accordance with the project contract requirements. After receiving the opinions and suggestions from scholars and commissioners on June 15, 2021, this project modified the term report and replied to scholars’ and commissioners’ opinions and suggestions, and submitted their consent replies to the bureau for review on June 30. Extracts of the enforcement results of all work items are shown as follows: This project has been horizontally combining other projects’ capacity of unmanned aerial vehicle (UAV), grasping the distribution of exposed riverbed in a rolling manner and urging the river management offices to finish exposed riverbed improvement earlier under the concept of preventive deployment. A total of 651.2 hectares of exposed reverbed have been improved in 2020, which is 8% higher compared with 2019 and the most improvement areas for exposed reverbed in the recent five years, and correspond to 16.73 tons of PM10 emission reduction based on their actual control periods. In addition, this project invited the 7th River Management Office to extract river dust improvement experiences from Zhuoshui River to go forward the creative and strategic thinking by hosting an inter-office observation tour for river dust improvement of Zhuoshui River. This project also drafted a battle strategy map for Gaoping River dust improvement with river management offices by holding the liaison meeting for Gaoping River dust control. The river management offices have been adding scattering grass seed method by using Plant Protection UAV and spraying water method for emergency response capacity by using refitted excavators to reinforce river dust prevention capacity under the concept of site-based and time-based exposed riverbed improvement. The highest maximum hourly average concentration is 440.3 μg/m3 based on analyses of three river fugitive dust episode days during January to December of 2020, which is 27% lower compared with 2019 (601.7 μg/m3). Furthermore, this project has utilized ISCST3 Dispersion Model with three times (May 4, May 14 and May 15, 2021) of river dust early-warning data provided by Environmental Protection Administration (EPA) to simulate the PM10 incremental concentrations at monitoring stations and potential impact levels and extents six times in a rolling manner and also compared the simulation results with UAV aerial photographs to analyze the critical exposed riverbed that may cause river fugitive dust events. This project has offered related information to river management offices to go forward preventive dust control operations so that the river dust influence concentration or occurrence probability may decrease. There is no river fugitive dust episode day during January to May of 2021, which is a significant progress on number of episode days compare to the same periods in the past four years (2017~2020). As regards the environmental cleanup, this project has finished 3057.8 kilometers of river dust environmental cleanup with a total PM10 emission reduction of about 7.9 tons. With respect to the river dust educational propaganda, a training session of river dust education for villages along the Gaoping River, three propaganda of river dust education for schools and a river dust pre-notification and self-protection drill have been held this year. Through the questionnaire survey after the educational propaganda, 95% of the respondents gave positive evaluation to Environmental Protection Bureau, Pingtung County Government for their promoting related work regarding river fugitive dust control. Furthermore, according to the results of the public satisfaction survey executed by Nsysu Survey Center, the public gave this county a positive rating of 89% for river dust improvement, which was consistent with the result of this project’s questionnaire survey. As for 2020 EPA evaluation, both achieving rates of river dust improvement items are 100%.
