(一)環境負荷及變化趨勢 104年臺南市人口數188.5萬，密度860.2人/km2，人口數每年持續成長，在六都直轄市中排名第六；本市工廠約8,831家，密度約為28.9家/km2；列管工廠家數2,282家，以塑膠製品製造業所列管的362家為最多(約占總列管家數15.9%)，其次為金屬工業296家(約占總列管家數13%)，再則為加油站業290家(約占總列管家數12.7%)及金屬表面處理業208家(約占總列管家數9.1%)；本市營建工地數104年呈現下降趨勢，目前工地數為9,688處，其中一級工地3,120處，二級工地為5,399處。 本市總車輛數為193.7萬輛，每人擁有車輛數為1.03輛/人，其中汽車數約54.9萬輛、機車數約128萬輛，近十年車輛數都呈現成長之趨勢，但機車數在100年起呈現負成長。本市發油量及加油站設站數皆呈減少之趨勢，發油量自94年1,182千公秉至104年為1,086千公秉，近十年來下降8%；加油站設站數則由95年302站減少到目前的277站。 (二)空氣品質現況及問題分析 臺南市空氣品質不良比例，自95年7.62%下降至104年0%，良好比例則呈現逐年提升為36.2%，創下本市歷年最佳紀錄，顯示近年來本市的管制策略具成效。 各項空氣污染物濃度，近年大致呈現改善趨勢，其中PM10年平均值及日平均值更是首次低於法規標準值。分析95~104年之監測資料，PM10年平均值改善率為26.6%，日平均值改善率為22%；PM2.5年平均值改善率為37.2%，24小時平均值改善率為29%；O3小時平均值改善率為18.6%，八小時平均值改善率為15%；SO2年平均值改善率為33%，小時平均值改善34.5%、NO2年平均值改善率為23.7 %，小時平均值改善率為24.2%；CO小時平均值改善率為19.8%，八小時平均值改善率11.4%。從長期變化趨勢來看，顯示近年臺南市施政方向正確且空氣品質改善策略奏效。 本市整體細懸浮微粒指標值，低等級(≦35µg/m3)由103年65.8%增加至104年73.9%，而高、非常高等級不良率(≧54µg/m3)由103年10.2%降至104年8.2%，顯示本市PM2.5已有改善。 (三)空氣品質模式模擬分析結果 進行2010年四個月(1, 4, 7, 10月)之模式模擬，分析本市減量策略推動後之PM2.5、PM10與O3空氣品質改善成效，評估臺南市達到空氣品質目標之程度，評估結果除PM10年平均值及O3最大小時值在109年可達到空氣品質標準外，其餘污染物仍無法達成空氣品質標準。 (四)分析各類排放源結構 依據TEDS 8.1排放量資料庫及本計畫檢討更新結果，本市99年點、線、面源之排放清單已更新，各類污染源之排放狀況如下表所示： 類別 TSP PM10 SOx NOx NMHC 點源(公噸/年) 2,717 1,871 3,855 5,593 5,103 面源(公噸/年) 34,363 10,439 419 1,692 240,884 線源(公噸/年) 2,780 2,006 130 20,152 16,857 總排放量(公噸/年) 39,860 14,316 4,404 27,437 46,048 (五)檢討修正本市空氣污染管制策略 本計畫針對104年空氣污染管制目標，包含固定、移動、逸散污染源及便民措施等共計74項管制工作進行追蹤及檢討，大致來說各計畫達成度良好。 因應本市102年空氣品質懸浮微粒呈現惡化情形，故協助環保局擬定「亮麗晴空-懸浮微粒削減管制行動計畫」，針對9項容易產生懸浮微粒的污染來源，確立管制目標，擬定37項行動管制策略，希望在109年懸浮微粒及細懸浮微粒年平均濃度達成65 µg/m3、15 µg/m3空氣品質目標。 本計畫協助研擬104年版臺南市空氣污染防制計畫書，規劃了104-109年之空氣污染管制目標及研擬本市空氣品質管制策略，包含固定、移動、逸散污染源等16項策略59項工作目標進行管制。 (六)管理空氣污染防制計畫辦理品質及成效 1.環保署考評成績檢討 103年度環保署所公佈之考評成績，本市獲得85.22分，在六都評等中獲得優等，顯示本市各項工作獲得委員及環保署肯定。 2.擬訂「104年度臺南市空氣改善維護計畫管理及考核評分辦法」，對各計畫實施管理及考核評分。 3.104年度各委辦計畫考評結果：在執行性重點計畫中以「柴油車動力計排煙檢測計畫」得分最高，該計畫皆能依據工作規劃進度執行、每月工作進度達成率佳、人員離職或異動率低、資料庫查核無缺失、AQMP月查核及重點工作特色執行成效等執行狀況良好，整體表現優異。 (七)空污管制工作之民眾滿意度調查 本計畫針對104年度之問卷調查結論：在一般民眾滿意度調查，68.9%民眾對於台南市環保局改善空氣污染之整體努力感到滿意，初步解析其結果可能與本市103年空氣品質良好率上升、不良率下降及陳情案件下降有密切關係。 (八)空氣品質淨化區維護管理 1.空品淨化區基地數自100年(192處)起逐年增加104年達220處，增加28處，包含環保公園23處、環保林園大道10處、社區綠帶187處，總面積78.45公頃、長度74.24公里。 2.104年設置補助申請共計10件，經審查後全數核定，面積達0.7902公頃；另淨化區維護補助經費共94處基地提出，申請金額為191.701萬元，經審核予以補助191.024萬元。 3.完成各淨化區二次平時考核，共計考評376處次，獲得90分以上的基地共計34處；81~89分128處；80分以下26處。 4.協助環保局及社區等團體獲得環保署第二屆「空氣品質淨化區優良認養單位甄選及獎勵活動」特優、優等及績效卓著佳績。
