【摘要】：于2013年4月,在葛洲壩1號(hào)船閘下游閘首,利用雙頻識(shí)別聲納(DIDSON)對(duì)船閘不同運(yùn)行狀態(tài)下(關(guān)閘、放水、開(kāi)閘)近閘區(qū)域的魚(yú)類(lèi)數(shù)量和密度進(jìn)行了定點(diǎn)探測(cè),并同步進(jìn)行水質(zhì)水動(dòng)力現(xiàn)場(chǎng)監(jiān)測(cè),研究船閘啟閉閘門(mén)對(duì)近閘區(qū)域魚(yú)類(lèi)活動(dòng)規(guī)律的影響。研究結(jié)果表明:葛洲壩1號(hào)船閘在放水期間,對(duì)下游近閘區(qū)域流速及水體溶解氧(DO)濃度影響較大,對(duì)pH值及水溫的影響不明顯;魚(yú)類(lèi)密度與流速及DO呈顯著相關(guān)性,與pH值及水溫的變化相關(guān)性不顯著;船閘在放水期間對(duì)近閘區(qū)域水體環(huán)境的改變,產(chǎn)生了誘導(dǎo)魚(yú)類(lèi)進(jìn)入閘室下游出口的明顯趨勢(shì)。本研究為中低水頭水利樞紐船閘與魚(yú)道結(jié)合的可行性研究提供基礎(chǔ)數(shù)據(jù),同時(shí)也為魚(yú)類(lèi)行為學(xué)的研究提供參考依據(jù)。
[Abstract]:In April 2013, at the downstream head of Gezhouba No. 1 shiplock, the number and density of fish near the lock under different operating conditions (closing, releasing and opening) were detected by using dual frequency identification sonar (DIDSON). The water quality hydrodynamic field monitoring was carried out simultaneously to study the influence of lock gate on the fish activity in the area near the lock. The results show that during the discharge of Gezhouba No. 1 lock, it has a great influence on the velocity of water near the sluice and the concentration of dissolved oxygen (DOO) in the water body, but has no obvious effect on the pH value and water temperature, and the density of fish has a significant correlation with the velocity of water and do. There was no significant correlation between the change of pH value and water temperature, and the change of the water environment in the near lock area during the release period of the lock resulted in an obvious tendency to induce fish to enter the downstream outlet of the lock chamber. This study provides the basic data for the feasibility study of the combination of the lock and the fish track of the middle and low water head water conservancy project, and also provides the reference for the study of fish behavior.
