【摘要】 以广东省一村级河长监管河段岸线管理范围为研究区域,利用民用轻型无人机采集现场数据,经影像拼接、目标解译和相关资料叠加分析,快速获取了岸线侵占后的界桩、围栏与补种乔灌草等整改措施实施情况,通过整改设计图与遥感判读出的现状结果对比,精准筛查整改措施未落实或整改不到位等监管所需掌握的现存问题区域。研究结果显示:相比传统现场核查,基于无人机遥感方法对于点状目标(如界桩)和线状目标(如围栏)的排查更加高效直观,对面状分布目标(如植被栽植)的复核更具备现场核查所无法比拟的优势,部分不易到达区域的复核的任务也都能较好地解决。无人机遥感作为获取空间数据的重要手段之一,具有机动灵活、影像分辨率高等特点,基于无人机技术的岸线监管可较好解决当前日常监管中存在的问题,对河流岸线监管具有重要意义,应用前景广阔。更多还原

【Abstract】 In the process of the comprehensive implementation of the river chief system,the river chief must strictly control the control the ecological space along river shorelines control the ecological space along river shorelines.Thus,it is necessary to analyze and govern outstanding problems such as occupation,abuse,and unauthorized use of shorelines.Traditional ground monitoring has been unable to fully meet the demands of the current efforts to manage/protect the shoreline.The study area is a river shoreline which was supervised by a village chief in Guangdong.Using civil small unmanned multirotor aircraft,aerial photos of the shorelines were collected.The images were then extracted,interpreted,and analyzed,and measures to identify problem areas and rehabilitate the shoreline were determined.This result can provide useful reference for supervision departments in on-site inspections.The river inspection workload can be greatly reduced while efficiency can also be significantly improved.Compared with traditional ground monitoring,the results of this research show that unmanned aerial vehicle(UAV)-based remote sensing technology is more efficient and intuitive in the detection of point targets(e.g.,boundary stones)and linear targets(e.g.,enclosures).It has superior advantages in the monitoring of surface distribution targets(e.g.,vegetation);the problem of monitoring hard-to-reach areas can also be solved.The equipment used in this research is a widely used product in the market.The process of obtaining UAV photos is simple and easy to learn,and can be applied in the monitoring of village-level river sections.With its operational convenience and intelligence,it can conduct inspections of fixed river shorelines,eliminating the need for manual and repeated inspections.Taking into account some limitations on the use of UAV remote sensing technology,a combination of satellite remote sensing,UAV remote sensing,and ground investigation is needed in the supervision of long river shorelines to achieve complementary advantages.After the application of this UAV remote sensing technology to river shoreline resource supervision,some defects in UAV technology,sensors technology,aerial data processing technology,and remote sensing image interpretation were also found.These can be used as a reference for subsequent research and development.UAV remote sensing is an important method for obtaining spatial data with flexible,high-resolution image characteristics to solve the problems of daily supervision.In this study,we explored the application of UAV to monitor river shorelines.The application of UAV remote sensing technology is proposed to support the river management system,which is of great significance for waterfront shoreline management.更多还原
