本研究中首先調查了廣州市河涌沉積物及底棲生物體內重金屬含量及分佈，並以珠江水產研究所培育的水生實驗動物?劍尾魚為實驗材料，利用環境生物技術，電鏡觀察等技術方法研究了重金屬?汞對劍尾魚組織的毒害及機體必需微量元素硒對其毒害的拮抗性影響。 -
The main study in this paper included as follows : the content and distribution of heavy metals in sediments and benthic organisms from the sewage stream in guangzhou city ; the acute toxicity and joint toxicity of mercury and selenium to swordtail fish ( xiphophorus helleri ) ; the damage of mercury to the indexes of antioxidant system in the gills and livers in swordtail ( including the measurement of the activities of total antioxidative capacity [ t ~ aoc ], superoxide dismutase [ sod ], glutathione peroxidase [ gsh - px ] and the concentration of malondiald - ehyde [ mda ] ) and the relief effects of selenium on it, as well as the physiological damage of mercury on the tissues, namely : the antagonistic effect of na + - k + ~ atpase activity on the tissues between selenite and mercury, and the ultrastructural damage under the exposure of mercury
研究內容主要有：廣州市河涌沉積物及底棲生物體內重金屬含量及評價；汞和硒對劍尾魚的急性毒性和聯合毒性及安全濃度的評價；汞對劍尾魚鰓和肝臟中抗氧化系統的毒性，包括對總抗氧化能力、超氧化物歧化酶、谷胱甘肽過氧化物酶活力及丙二醛含量的測定及硒對其保護作用；汞對劍尾魚組織生理毒性即：汞對na ~ + - k ~ + atpase活力的影響及硒的保護作用和汞和對劍尾魚組織超微結構的損傷等。以高氯酸?硝酸消化法和火焰原子吸收分光光度法測定了廣州市河涌沉積物和底棲生物中重金屬含量。 -
One of wetland s function is to filter the pollutants. when the river goes through wetland with pollutants, the hydrophyte will slow down the speed of the stream and attract heavy metal so that those pollutants will steep in the ground. the chemical reaction of nitrogen and phosphorus from those water plants prevent water from oxidation
濕地具有過濾污染物的功能，當河水挾帶著污染物流經濕地時，濕地上的水生植物，會使水流速度減緩，吸附重金屬，且讓污染物沈澱在濕地的底部，並藉著植物留存氮和磷，來預防水質優氧化。 -
What ' s more, we put forward some experienced formulas on the basis of the cortical analysis. the result of the research show that by installing diffluent piers with low ridge, we can eliminate the root of oscillatiny water jump, perfect the energy dissipation effect of water jump, also, we can improve the flow condition of down - stream. the fact that the main flow of down - stream is in the middle, not only effectively lower the speed of the bottom flow in the ridge rear, alleviate the erosion to the river bed, but also avoid the heavy wave resulted from the main flow in the surface, thus improve the surface wave of down - stream obviously. we can work out the body style parameters of diffluent piers with low ridge according to the project flow condition and experience formulas, and then reckon the down - stream surface wave condition for the protected building of the down - stream bank
研究結果表明：設置低坎分流墩后，消除了擺動水躍水舌擺動的根源，提高了水躍的消能效果，改善了下游水流流態。下游水體的主流在中部，既有效的降低了坎后水流底流速，減輕水流對河床的沖刷，又避免了主流位於表面導致波浪過大的結果，下游的水面波浪明顯得到削減。依據經驗公式，可根據工程水流條件設計出低坎分流墩的體型參數，進而估算出下游沿程的水面波浪，為下游岸邊的砌護提供依據。 -
