摘要

近年來，科技的進步，亦幫助人們能夠更加詳盡地了解到環境之狀況。以本研究中所使用之自動監測船為例，有別於傳統的監測方式，體積較小、較便於操作且防水，並且能運用在各個水域中。
本研究將自動監測船應用至新竹縣寶山水庫，進行水庫內沿岸的監測後，再針對監測結果中可能為污染熱區之區域進行迴圈型之監測。監測期間自2018年6月21日至2019年5月15日，在完成監測後即可將數據整理，匯入ArcGIS軟體中進行水質濃度分析。本研究所使用之軟體為ArcGIS將得到之水質資料進行分析，再透過軟體內的特殊分析工具的Kriging內插法分析監測區域內的水質項目濃度分布，並且以不同之顏色能夠將濃度低至高作為漸層比對。另外，可以將寶山水庫之土地利用圖做為底圖，能夠更加了解污染熱區之分布位置，亦能再找出污染源之變化趨勢並加以分析。
本次研究之結果顯示，寶山水庫內之葉綠素a、溶氧濃度以及pH值在靠近寶山水庫二號監測站及碧湖周圍之濃度較監測平均值高，監測到的最高濃度分別較平均值高0.02、0.4mg/L及26μg/L。鉀離子之濃度則是在寶山水庫二號監測站附近農地密度較高之區域之濃度介於73 mg/L至96.6 mg/L，相較於靠近寶山水庫取水口附近之平均鉀離子濃度1.8 mg/L來說較高。綜合上述幾項水質檢測之結果顯示在寶山水庫二號監測站周圍較需注意。目前自動水質監測系統仍有電力問題須克服。若未來能夠克服電力之問題，該系統及能夠以全天連續監測之方式長期應用於水庫中，並且將監測之資料應用於其他分析中，以提供相關單位著手於水質改善之管理。

In recent years, advances in technology have helped people understand the state of the environment in more detail. Taking the automatic monitoring ship used in this study as an example, it is different from the traditional monitoring method, small in size, easy to operate and waterproof, and can be used in various waters.
In this study, the automatic monitoring ship will be applied to the Baoshan Reservoir in Hsinchu County for monitoring the coastal areas of the reservoir, and then the loop-type monitoring of the areas that may be polluted hot areas in the monitoring results will be carried out. During the monitoring period, from June 21, 2018 to May 15, 2019, after the monitoring is completed, the data can be sorted and imported into ArcGIS software for water concentration analysis. The software used in this study analyzes the water quality data obtained by ArcGIS, and then analyzes the concentration distribution of water quality items in the monitoring area through Kriging interpolation of special analysis tools in the soft body, and can use the color to be low to high in different colors. Gradual comparison. In addition, the land use map of Baoshan Reservoir can be used as a base map to better understand the distribution location of the polluted hot zone, and to identify the trend of pollution sources and analyze them.
The results of this study showed that the concentration of chlorophyll a, dissolved oxygen concentration and pH value in Baoshan Reservoir near the monitoring station No. 2 of Baoshan Reservoir and Bihu Lake were higher than the monitoring average, and the highest concentrations monitored were higher than the average. 0.02, 0.4 mg/L and 26 μg/L. The concentration of potassium ions is between 73 mg/L and 96.6 mg/L in the area with high density of agricultural land near the monitoring station No. 2 of Baoshan Reservoir, compared with the average potassium ion concentration near the water intake of Baoshan Reservoir: 1.8 mg. /L is higher. The results of the above-mentioned several water quality tests show that it is more important to pay attention to the monitoring station No. 2 of Baoshan Reservoir. At present, automatic water quality monitoring systems still have power problems to overcome. If the power problem can be overcome in the future, the system can be used in the reservoir for a long time through continuous monitoring throughout the day, and the monitoring data will be applied to other analyses to provide the relevant units to start the management of water quality improvement.
