Supervisory Monitoring Technology System for Key Drinking Water Sources in Guangdong-Hong Kong-Macao Greater Bay Area by CUI Fan, KOU Xinyue, FENG Youbin, XIE Yuning, HE Yingqing, ZHENG Ning

“…In order to resolve the contradiction between the high demand for water resources,water ecology and water environment in the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) and the insufficient supervision capabilities in the water conservancy industry,and achieve the transformation from passive management to active management of key drinking water sources in the GBA,this paper carries out supervisory monitoring of key drinking water sources through remote sensing macro monitoring,UAV cruise monitoring,fixed-point monitoring and other intelligent monitoring technology system.The results show that:①After application of a supervisory monitoring technology system for key drinking water sources,the full-coverage,dynamic and quasi-real-time monitoring of 35 key water sources in the GBA is realized,and the risk sources and water problems can be identified efficiently.②For identifying five suspected risk sources in water source areas,namely construction projects,key river (reservoir) tributaries,temporary shipping stops,material stacking places,agricultural production activities by remote sensing macro monitoring and UAV cruise monitoring,the accuracy rate is 65.7%.③For the chlorophyll a and COD_Mnmonitoring of the water source of main Guangzhou-Dongguan-Huizhou Dongjiangbei River by remote sensing macro monitoring and artificial fixed-point monitoring during the same period,the monitoring results of the two technical means are in good agreement.Therefore,with application of the technology system in supervision and management of key drinking water sources,the smart water conservancy supervision and business management are deeply integrated,and the effective technical means for supervision and management are available.…”

Spatial and Temporal Distribution of Sand Mining in Poyang Lake and Its Impact on Lake Basin Morphology Based on Remote Sensing Images by LIU Jiahao

“…The results show that: ① sand mining vessels were mainly distributed in the north lake part of Poyang Lake from 2000 to 2006, and the number of sand mining vessels plummeted in 2008 due to the impact of the banning policy, and 2016 was the peak of sand mining activities, in which the policy regulation is the main factor for the change of spatio-temporal distribution and number and scale of sand mining vessels in Poyang Lake from 2000 to 2021; ② the human sand mining activities have affected to a certain extent the hydrological sediment balance of Poyang Lake to a certain extent; ③ sand mining activities led to a decrease in the beach area in the inlet channel of Poyang Lake and Songmen Mountain area, while the net increase in the beach area in the southeast area of Tangyin was about 7.95 km², mainly due to siltation caused by the spreading of sediments from inlet tributaries of the lake. This study not only assesses the effectiveness of the regulation of sand mining activities in Poyang Lake in recent years, but also provides a reference for the regulation of sand mining activities in similar waters and the assessment of its effectiveness.…”
