The invention discloses a sensor water body parameter measuring device and method for identifying water body methane boiling emission, the measuring device comprises a control box and a box body fixed in a floating ring, a vacuum pump is arranged in the control box, the vacuum pump comprises a gas inlet and a gas outlet, the gas inlet is connected with a first gas pipe communicated with the outside, and the gas outlet is connected with a second gas pipe communicated with the outside; the air outlet is connected with a second air pipe, and a first air vent and a second air vent located on the opposite side of the first air vent are formed in the box body; the second air pipe is communicated with the first air vent; the second air vent is connected with a third air pipe surrounding the box body by a circle. The method comprises the following steps: when identifying boiling discharge of methane in a water body, calculating carbon dioxide diffusion flux, methane diffusion flux and methane boiling flux discharged by the water body according to carbon dioxide concentration and methane concentration in each time period when a vacuum pump stops working; and water body methane boiling discharge is identified by analyzing methane concentration data at a set time interval. According to the method, water body methane boiling emission is identified, and the accuracy of water body methane emission flux calculation is improved.

    本发明公开了一种识别水体甲烷沸腾排放的传感器水体参数测量装置及方法,测量装置包括控制盒和固定在漂浮圈中的箱体,控制盒内设有真空泵,真空泵包括进气口和出气口,进气口连接有与外界相通的第一气管,出气口连接有第二气管,箱体上开设有第一通气口,以及位于第一通气口对侧的第二通气口;第二气管与第一通气口连通;第二通气口连接有围绕箱体一圈的第三气管。本发明识别水体甲烷沸腾排放时,根据每次真空泵停止工作时间段的二氧化碳浓度和甲烷浓度计算水体排放的二氧化碳扩散通量、甲烷扩散通量和甲烷沸腾通量;通过分析设定时间间隔的甲烷浓度数据识别水体甲烷沸腾排放。本发明识别水体甲烷沸腾排放并提高了水体甲烷排放通量计算的准确性。
