中文摘要	本計畫主要針對台灣本島及離島之重點水庫、一般水庫及主要入庫溪流水質水量監測，並彙集調查結果資料，掌握水體水質變化，提供環保單位污染整治參考。要入庫溪流水質與流量調查，於 21 座水庫之入庫溪流計有 24 個測點，每月監測一次水質。監測期間各測站有部分測值不符合所屬陸域地面水體水質標準情形，以大腸桿菌群超過標準占最高比例 (58 %)，生化需氧量比例次之 (37 %)。以河川污染等級評估，各測站大致屬未(稍)受污染等級。其中僅 2 個測站屬輕度污染等級，主要影響因素為水中懸浮固體較高。另 2 個測站屬中度污染等級，其中港西抽水站水質較差，溶氧較低，有機污染物較高。重點水庫水質計有 21 座水庫，74 個測點，114 個水樣，每月監測一次。監測結果顯示，各水庫不符合甲類陸域地面水體水質標準，以pH 值超過標準比例占最高 (31 %)，總磷與溶氧量比例次之 (26 %、21 %)。整體而言，監測期間以日月潭水庫水質較佳，貧養等級占最高比例 (67 %)，蘭潭水庫水質次佳，均屬普養等級 (100 %)，明德水庫及鳳山水庫水質較差，均屬優養等級 (100 %)。與近 5 年水質比較，石門水庫卡爾森指數下降水質略有轉佳趨勢，德基水庫、霧社水庫、曾文水庫、白河水庫及鏡面水庫卡爾森指數有上升趨勢，水質略有轉差，其餘水庫監測期間水質變化，與歷年結果相近。一般水庫水質計有 30 座水庫，30 個測點，每季監測一次。監測結果顯示，本島一般水庫水質除大埔水庫監測期間，水面均佈滿布袋蓮，無法採樣，其餘皆以普養等級占最高比例 (75 %~100%)，金門縣、連江縣及澎湖縣離島水庫水質較差，大致以優養等級占較高比例 (25 % ~ 100 %)。一般水庫水質與近5年水質監測結果比較，后沃、儲水沃下壩及坂里水庫卡爾森指數有降低趨勢，水質略有轉佳，其餘水庫則長期屬優養等級，無明顯變化趨勢。

摘要	The aim of this project is to properly understand the changing trend of water quality in those types of water bodies that including “Major reservoirs,” “The other reservoirs” and “Major Rivers” of not only Taiwan main island but also offshore islands by the water quality monitoring. For the water quality and discharge investigation of “Major Rivers,” water quality monitoring was conducted once a month in twenty-four monitoring stations where located in twenty-one rivers. However, there were not all monitoring measurements could meet Class-A or Class-B criteria of“Surface Water Classification and Water Quality Standards”in all monitoring stations during monitoring period, especially on coliform group (58 %) and BOD5 (37 %), respectively. On the other hand, most of monitoring stations were categorized to non(slightly)-polluted level, there were only two monitoring stations categorized to light-polluted level, which may resulted from higher suspended solids concentration; furthermore, only two stations categorized to medium-polluted level, not only lower dissolved oxygen but also higher organic pollutants concentrations were observed in Gang Si pumping station. For the water quality investigation of “Major reservoirs”, water quality monitoring was conducted once a month in seventy-four monitoring stations where located in twenty-one reservoirs.

However, the results indicated that there was the highest proportion of oligotrophic ratings for the water quality of the Sun-Moon-Lake Reservoir (67%), on the contrary, 100% of mesotrophic ratings was observed for Lan-Tan Reservoir; furthermore, 100% 0f eutrophic ratings were observed for not only Mingten Reservoir but also Feng-Shan Reservoir.

摘要

The aim of this project is to properly understand the changing trend of water quality in those types of water bodies that including “Major reservoirs,” “The other reservoirs” and “Major Rivers” of not only Taiwan main island but also offshore islands by the water quality monitoring. For the water quality and discharge investigation of “Major Rivers,” water quality monitoring was conducted once a month in twenty-four monitoring stations where located in twenty-one rivers. However, there were not all monitoring measurements could meet Class-A or Class-B criteria of“Surface Water Classification and Water Quality Standards”in all monitoring stations during monitoring period, especially on coliform group (58 %) and BOD5 (37 %), respectively. On the other hand, most of monitoring stations were categorized to non(slightly)-polluted level, there were only two monitoring stations categorized to light-polluted level, which may resulted from higher suspended solids concentration; furthermore, only two stations categorized to medium-polluted level, not only lower dissolved oxygen but also higher organic pollutants concentrations were observed in Gang Si pumping station. For the water quality investigation of “Major reservoirs”, water quality monitoring was conducted once a month in seventy-four monitoring stations where located in twenty-one reservoirs. The results showed that all “Major reservoirs” could not meet Class-A criteria of“Surface Water Classification and Water Quality Standards”, among these measurements over the standard, the highest ratio item was pH (31%), second, total phosphorus was 26%, and third DO was 21%, respectively. However, the results indicated that there was the highest proportion of oligotrophic ratings for the water quality of the Sun-Moon-Lake Reservoir (67%), on the contrary, 100% of mesotrophic ratings was observed for Lan-Tan Reservoir; furthermore, 100% 0f eutrophic ratings were observed for not only Mingten Reservoir but also Feng-Shan Reservoir. Compared to the recent five years monitoring, the decreasing Carlson trophic state index could be observed in Shimen Reservoir, however, the increasing trends (worse water quality) of Carlson index were found in Te-Chi Reservoir, Wu-She Reservoir, Tsengwen Reservoir, Pai-Ho Reservoir and Ching-Mien Reservoir, respectively. While the water quality changes during the monitoring period at the other reservoirs were within historical norms. For the water quality investigation of “The other reservoirs,” water quality monitoring was conducted once every season in thirty monitoring stations where located in thirty reservoirs. The results showed that the highest proportion of mesotrophic ratings for “The other reservoirs” of Taiwan main island, except for Ta-Pu Reservoir that being unable to sample resulted from full of Water Hyacinth on the surface of water during monitoring period, on the contrary, the worse water quality (the higher proportion of eutrophic ratings) was observed in “The other reservoirs” of Taiwan offshore islands, such as Kinmen County, Lienchiang County and Penghu County. Compared to the recent five years monitoring, the decreasing Carlson trophic state index (better water quality) could be observed in Houwo, Chu-Shui-Wo Lower Dam and Pan-Li Reservoir, respectively.
