中文摘要	本計畫主要採取測點中之微生物、藻類、魚類、蝦蟹及底棲生物整合其各項生物指標，並利用當中優勢魚種、水棲昆蟲、藻類及多樣性指數（Species diversity index）判定水質等級，藉此得知淡水河整治的環境有無改善。大漢溪大溪以上河域總生菌數、大腸桿菌群及硫氧化菌數稀少。武嶺橋至豆荳世界的總生菌數及大腸桿菌群開始明顯上升。淡水河從新店溪及大漢溪匯流開始至二重疏洪道注入之前的這段河域，微生物的數量均顯著高於二重疏洪道以下的河域。大漢溪及淡水河23個測站，水層中及石頭表面共記錄295種藻類，分別為藍綠菌29種、矽藻141種、綠藻118種、裸藻5種及雙渦邊藻類2種，而矽藻種類占分布的大多數。下游感潮段浮游藻類調查結果所估算之GI值均甚低，大致能反應下游河域的藻類群聚屬於嚴重污染水域的特性。 98年度大漢溪和淡水河共記錄35科74種魚類，大漢溪河域記錄35種魚類，淡水河43種魚類。溪洲大橋至後村圳取水口非感潮河段共記錄31種魚類，城林橋至新海橋感潮河段共捕獲7種魚類，大眼海鰱最常見，烏魚出現在接近淡水河交匯口河域。新店溪匯流處至淡水河出海口記錄43種魚類，烏魚最常見，淡水河感潮區新增12種魚類記錄。 98年淡水河及大漢溪共採獲89個類群的底棲生物，總數達23,214隻個體。大漢溪底棲生種類的多樣性高於淡水河，大漢溪上游非感潮河域以水棲昆蟲為主，下游感潮河域底質中僅有耐污的環節動物。淡水河的物種數明顯比大漢溪河段少，以環節動物及甲殼動物為主。綜合整理97-98年度調查所得之淡水河系生物指標，結果顯示感潮河域水質最差的是大漢溪(城林橋至大漢溪口)，最佳河域是淡水河本流(洲美快速路至出海口)。非感潮河域水質最差的是基隆河(長安大橋至瑞芳)，最佳河域是新店溪碧潭至南北勢溪匯口，大漢溪(溪洲橋至鳶山堰)的綜合得分與新店溪碧潭至南北勢溪匯口河域及相近。根據97-98年度調查分析結果，淡水河系在94年之後生物群聚的多樣性逐漸增加，其中以魚類的群聚改變最為明顯，97-98年的物種豐富度是歷年最高的記錄。目前的淡水河除了大漢溪城林橋至新海橋之間的河域屬於嚴重汙染之外，其他河域已逐漸轉為中度汙染，部分原為中度汙染水域也逐漸轉為輕度汙染，水質獲得明顯改善。

摘要	In this research, we primarily sample the microorganism, algae, fish, shrimp, crab and benthonic organism at all monitoring site. We analyse data to understand the species diversity index of the fish, aquatic insect and algae. We finally integrate each biological indicator to determine the water quality rank and take advantage of this to know whether the renovation of Dan-Shaei river was improved. Population density of micro-organism was low in Da-Han stream upper than Da-Si township, we have less total plate count, coliform and E. coli. The area range from Wu-ling bridge to Dou-Dou-Shih-Jie, total plate count and coliform of stream water increased conspicuously. In Dan-Shaei river, the population density of micro-organism was higher in the region between Sin-dian stream and Da-Han stream converge site, and from here down to Er-Chong flooding canal converge site. In this study, 295 taxa of algae were found from the collection of phytoplankton and periphyton. There were 29 taxa of cynobacteria, 141 taxa of diatom, 118 taxa of green algae, 5 taxa of euglenophytan and 2 taxa of dinoflagellate. The GI index derived from algae community indicated the downstream area was highly polluted in general. In one year of collection from Da-Han stream and Dan-Shaei river, 74 species belong to 35 family of fishes were found in 2009. In Da-Han stream, we had 35 species of fishes, non-tidal effected area from Si-Jhon bridge to Hou-Cun-jyun water collection site with 31 species, the tidal effected region from Chen-Lin bridge to Sin-Hai bridge with 7 species. Between Chen-Lin bridge and Sin-Hai bridge Megalops cyprinoides was common species and Mugil cephalus only can collected from the converge site. Dan-Shaei river was tidal effected from Sin-Dian stream and Da-Han stream converge site down to river mouth to Taiwan strait, we had 43 species of fishes in 2009, 12 species were new records, Mugil cephalus was the most common species. The benthic macroinvertebrate collected from Da-Han stream and Dan-Shaei river in 2009 total with 23,214 individuals belong to 89 taxa. The species diversity was higher in Da-Han stream than Dan-Shaei river. Non -tidal effected Da-Han upstream with more aquatic insect than the other area, tidal effected region only have pollution tolerant species such as annelid. The species richness in Dan-Shaei river lower than Da-Han stream, macroincertebrate community dominated with pollution tolerant annelid and crustacean. Dan-Shaei river sytem in 2008 and 2009, water quality indicated by IBI, FBI, EPT and BI, the most polluted area of tidal-effected region was from Chen-Lin bridge to Da-Han river mouth, the most clean water was in the area range between Jhou-Mei express way entrance and river mouth to Taiwan strait.

摘要

In this research, we primarily sample the microorganism, algae, fish, shrimp, crab and benthonic organism at all monitoring site. We analyse data to understand the species diversity index of the fish, aquatic insect and algae. We finally integrate each biological indicator to determine the water quality rank and take advantage of this to know whether the renovation of Dan-Shaei river was improved. Population density of micro-organism was low in Da-Han stream upper than Da-Si township, we have less total plate count, coliform and E. coli. The area range from Wu-ling bridge to Dou-Dou-Shih-Jie, total plate count and coliform of stream water increased conspicuously. In Dan-Shaei river, the population density of micro-organism was higher in the region between Sin-dian stream and Da-Han stream converge site, and from here down to Er-Chong flooding canal converge site. In this study, 295 taxa of algae were found from the collection of phytoplankton and periphyton. There were 29 taxa of cynobacteria, 141 taxa of diatom, 118 taxa of green algae, 5 taxa of euglenophytan and 2 taxa of dinoflagellate. The GI index derived from algae community indicated the downstream area was highly polluted in general. In one year of collection from Da-Han stream and Dan-Shaei river, 74 species belong to 35 family of fishes were found in 2009. In Da-Han stream, we had 35 species of fishes, non-tidal effected area from Si-Jhon bridge to Hou-Cun-jyun water collection site with 31 species, the tidal effected region from Chen-Lin bridge to Sin-Hai bridge with 7 species. Between Chen-Lin bridge and Sin-Hai bridge Megalops cyprinoides was common species and Mugil cephalus only can collected from the converge site. Dan-Shaei river was tidal effected from Sin-Dian stream and Da-Han stream converge site down to river mouth to Taiwan strait, we had 43 species of fishes in 2009, 12 species were new records, Mugil cephalus was the most common species. The benthic macroinvertebrate collected from Da-Han stream and Dan-Shaei river in 2009 total with 23,214 individuals belong to 89 taxa. The species diversity was higher in Da-Han stream than Dan-Shaei river. Non -tidal effected Da-Han upstream with more aquatic insect than the other area, tidal effected region only have pollution tolerant species such as annelid.

The water quality of Da-Han stream from Si-Jhon bridge to Yuan-Shan-Yan is similar to upstream of Sin-Dian stream. Biological community of Dan-Shaei river system with diversity increased from 2005 to 2009 gradually, the fish community with more species and higher population density.
