在县域低空资源利用中，普遍存在多部门重复飞行、数据孤岛、重建设轻运营等问题，严重制约基层治理效能提升。“综合飞一次”县域低空多跨协同治理模式以统一航线规划、统一数据采集、统一集中处理、按需定向分发4个环节为核心，将水利核心业务作为主线统筹全县域低空航线，创建跨域数据分发机制，构建低空资源集约利用治理闭环。模式设计以高频次的水库大坝巡检、河湖巡查等水利巡查为主干线，在执行水利监测任务时同步采集非水利要素，实现一次飞行、多方复用的目标。浙江省新昌县试点期间累计完成无人机飞行超3万架次，基层主动办件量上升32.5%，执法类投诉下降35%，平均处理时长缩短21.3%，初步验证了该模式在打破部门壁垒、提升治理效能方面的实践潜力，可为县域低空经济发展和数字化改革提供参考。

In the utilization of low-altitude resources at the county level, issues such as redundant drone patrols across departments, fragmented data silos, and a persistent emphasis on infrastructure construction over operational management have long constrained the improvement of governance efficiency at the county level. The county-level low-altitude multi-span collaborative governance model of “one comprehensive flight” centers on four key steps: unified route planning, unified data collection, unified centralized processing, and on-demand targeted distribution. It takes the core water conservancy business as the main line to coordinate low-altitude routes across the county, creates a cross-domain data distribution mechanism, and establishes a closed-loop governace system for intensive utilization of low-altitude resources. High-frequency water conservancy inspections including reservoir dam inspections and river and lake inspections, serve as the operational backbone, during which non-waterrelated environmental elements are simultaneously captured, enabling a single flight mission to yield multi-departmental value. During the pilot period in Xinchang County, Zhejiang Province, a total of over 30,000 drone flights were completed. The number of proactive cases handled at the county level increases by 32.5%, complaints related to law enforcement decrease by 35%, and the average processing time is shortened by 21.3%. These findings preliminarily validate the practical potential of this model for breaking down departmental barriers and improving governance efficiency and can serve as a reference for the development of county-level low-altitude economies and digital reform.
