摘要
为解决粤港澳大湾区水资源、水生态、水环境高需求与水利行业监管能力不足之间的矛盾,实现粤港澳大湾区重要饮用水水源地由被动管理向主动管理的转变,采用遥感宏观监测、无人机巡航监测、定点监测等多手段的智慧监测技术体系开展重要饮用水水源地监督性监测工作。结果如下:①采用重要饮用水水源地监督性监测技术体系实现了粤港澳大湾区35个重要水源地全覆盖、动态、准实时监管,高效发现风险源和水质问题;②采用遥感宏观监测和无人机巡航监测2种技术方法识别水源地5种疑似风险源——建设项目、重点监测的入河(库)支流、航运临时停靠点、物料堆放、农业生产活动,遥感宏观监测风险源准确率为65.7%;③对广州-东莞-惠州东江北干流水源地叶绿素a、COD Mn开展了同期的遥感宏观监测和人工定点监测工作,2种技术手段监测结果吻合性好。该技术体系应用于重要饮用水水源地监督管理,实现了智慧水利监管手段与业务管理深度融合,为监督管理提供有效的技术支撑。
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 Mn monitoring 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.
