108年度「屏東縣河川揚塵防制及改善推動計畫」期末報告(正式搞)

中文摘要 本計畫執行期自108年5月18日起至109年5月17日止,各項合約工作目標均已完成,並依規定於108年11月17日及109年4月27日前提交期中及期末報告初稿送審。以下即為各項工作執行成果摘要:本年度計畫執行期間共發生3次高屏溪河川揚塵事件(108年9月20~21日及109年2月15日與3月26日),為確認河川揚塵潛勢區,本計畫透由事件日分析與衛星圖資比對及現地巡查結果,持續調查評估可能的揚塵潛勢區,並劃定里港鄉沿岸村里為河川揚塵高度影響區域,而調查分析結果亦提供第七河川局做為揚塵抑制場址選址之參考。統計108年共改善601.8公頃河床裸露地,依據實際抑制期程推估,其PM10削減量為41.4公噸。為了提升相關單位及民眾應變之時效性,本計畫利用氣象預報資訊比對自擬之高屏溪河川揚塵預警參考標準,提供6次揚塵預警資訊,並成功預測108年9月21日中級河川揚塵事件、109年2月13日河道揚塵情事(該日亦為高雄市中級河川揚塵事件)、109年2月15日中級河川揚塵事件、109年5月15日河道揚塵情事(該日亦為高雄市中級河川揚塵事件)及109年5月16日河川揚塵預警(該日亦為高雄市中級河川揚塵事件),而為使未來能及早掌握揚塵可能之影響範圍,本計畫也以ISCST3模擬上述河川揚塵事件影響之程度及範圍,模擬結果顯示測站PM10增量濃度層級及擴散結果與事件日相似,顯示其結果有助於河川揚塵事件可能影響範圍之掌握。本計畫於執行期間共完成3,071.9公里之河川揚塵影響區域環境清理作業,推估PM10削減量為8.0公噸。另彙整各單位及各計畫於高屏溪沿岸鄉鎮之洗灑成效,截至108年共洗灑32,243.5公里,推估PM10削減量為83.8公噸,而根據中山大學社會科學院民意與市場調查中心之民眾滿意度調查結果,屏東縣高屏溪沿岸重點鄉鎮之民眾對於道路乾淨之改善給予87.7%的正面評價。本年度共辦理辦理2場沿岸村里河川揚塵教育訓練,3場學校河川揚塵教育宣導活動,2場高屏溪河川揚塵防制聯繫會議,以及1場河川揚塵預通報及自我防護演練作業,另透過本計畫之問卷調查,有96%之受訪者對於環保局推動河川揚塵防制相關工作給予正面的評價。

Prevention and promotion to improve river fugitive dust programs in Pingtung County, 2019.

英文摘要 The execution period of this project is from May 18, 2019 to May 17, 2020. All contract goals of work items have been accomplished and the first drafts of midterm report and term report have been submitted by November 17, 2019 and April 27, 2020 respectively. Extracts of the enforcement results of all work items are shown as follows: During the execution period of this project, three river fugitive dust episodes of Gaoping River occurred on September 20~21, 2019 and February 15 and March 26, 2020. To make sure the dust emission potential areas on riverbed, this project continued to investigate and assess possible dust emission potential areas by episode day analyses, satellite image comparisons and field inspections, and marked out the riverside villages of Ligang Township as high-impact areas of river fugitive dust. This project also offered the Seventh River Management Office related results as reference for selecting the dust control sites. A total of 601.8 hectares of exposed riverbed have been improved in 2019 and reduced about 41.4 tons of PM10 emission per year based on their actual control periods. To enhance response efficiency of departments and organizations concerned and the public, this project compared weather forecast information to the self-developed Gaoping River Dust early-warning parameters to predict river dust episode event and offered six times of dust early-warning information to the Bureau, and successfully predicted the intermediate river dust episode for Pingtung County on September 21, 2019, and the intermediate river dust episode for Kaohsiung City on February 13, the intermediate river dust episode for Pingtung County on February 15, the river course dust episode for Pingtung County and the intermediate river dust episode for Kaohsiung City on May15, and the intermediate river dust episode for Kaohsiung City on May 16, 2020. For holding the possible major impact areas earlier in future, this project also utilized ISCST3 Dispersion Model to simulate the impact levels and extents of the episodes mentioned above, and the results showed that the levels of PM10 incremental concentration at monitoring stations and dispersion trend of river fugitive dust met the actual situation occurred during episode days. It shows that the simulation results can help us have a better knowledge of the possible impact extents of river fugitive dust events. This project has finished 3,071.9 kilometers of environmental cleanup in river fugitive dust impact areas during the execution period with a total PM10 emission reduction of about eight tons. In addition, a total length of 32,243.5 kilometers of road washing/cleaning executed by government organizations concerned and related projects has been reached in 2019 with a total PM10 emission reduction of 83.8 tons. According to the results of the public satisfaction survey executed by Nsysu Survey Center, the public of the key townships along the Gaoping River in Pingtung County gave a positive rating of 87.7% for the improvement of road cleaning. Two training sessions of river dust education for villages along the Gaoping River, three propaganda of river dust education for schools, two liaison meetings for Gaoping River dust control and a river dust pre-notification and self-protection drill have been hold this year. Furthermore, through the questionnaire survey executed by this project, 96% of the respondents gave positive evaluation to Environmental Protection Bureau, Pingtung County Government for its promoting related work regarding river fugitive dust control.
