摘要:
长江扬州段是南水北调东线的源头水域,也是江淮生态大走廊的核心区,生态区域敏感性和重要性尤为突出。通过高分辨率卫星遥感筛查-无人机遥感详查-地面人工核查的星空地协同技术对长江扬州段沿岸自然岸线保有率、土地利用状况以及周边环境风险源进行全面调查。结果表明:(1)长江扬州段自然岸线保有率为46.20%,岸线范围内建设用地占比达33.35%,开发强度较高;(2)沿岸有码头114座,入江排口104个,部分排口存在水色异常等环境问题;(3)沿江生态保护红线区域内存在加油船溢油现象和驳船违规堆放固体废弃物等环境安全隐患。

Abstract:
Yangzhou section of the Yangtze River is the water source area of the East Route of the South to North Water Diversion Project and the core area of the Yangtze-Huaihe River Ecological Corridor, and its ecological sensitivity and importance are particularly prominent. This paper conducted a comprehensive investigation on the natural shoreline retention rate, landuse status and risk sources of surrounding environment along the Yangzhou section of the Yangtze River based on the technology of high-resolution satellite-UAV-ground collaboration. The results show that: (1) the natural shoreline rate of Yangzhou section of the Yangtze River is 46.20%, and the construction land within the shoreline accounts for 33.35%, indicating a high degree of development. (2) There are 114 wharves along and 104 sewage outfalls into the Yangtze River, and some outfalls have environmental problems such as abnormal water color. (3) Some potential environmental safety hazards in the ecological conservation redline area have been found,such as oil spill by tanker and illegal stacking of solid waste on barge.
