　　摘  要：景觀湖等水體流動性弱，易發生水體缺氧等水生態問題，嚴重損害水體質量，造成水體黑臭等現象，威脅著水體生態安全。為解決此類生態問題，保持水體良好的環境質量，研究一種基于太陽能的水體垂向循環裝置系統，以加強水體交換，從而提升深層水體溶解氧含量，改善水體生態循環。配套水質在線監測設備，基于LoRa自組網，保證在太陽能供電條件下裝置的持續在線，提出一種以溶解氧含量和設備剩余電量為聯合約束指標的動態調節方法，通過實時監測水體溶解氧含量，自動控制水體循環裝置調節水體溶解氧濃度。并在龍湖進行實驗驗證，實驗結果表明：裝置運行能有效提升水中溶解氧含量，減少溶解氧含量波動變化，有助于維持水體健康水質。

　　Abstract：Water bodies such as landscape lakes have weak fluidity and are prone to water ecological problems such as poor water oxygen, which seriously damages water quality, causes black and odorous water bodies and threatens water ecological safety. In order to solve such ecological problems and maintain good environmental quality of water body, a water body vertical circulation device system based on solar energy is studied to strengthen water body exchange, thus to increase the content of dissolved oxygen in deep water body and improve water body ecological circulation. Equipped with a water quality online monitoring equipment and LoRa self-organizing network, a dynamic adjustment method based on the constraint index of combining dissolved oxygen with remaining power of the equipment is proposed, which can ensure that the device is continuously on line under solar power conditions. By real-time monitoring of the dissolved oxygen content in water bodies, the water circulation device can automatically control the dissolved oxygen concentration in water bodies. Experiment carried out in Longhu shows that the device can effectively increase dissolved oxygen content, reduce the fluctuation of dissolved oxygen content, and help maintain healthy water quality of the water bodies.
