水利工程管理保护范围遥感划定方法研究与应用

Research and application of remote sensing-based methods for defifi ning the management and protection scope of water conservancy projects

摘要:

针对小型水利工程管理保护范围划定工作无现行规范标准指导，也无既定可适用的流程问题，提出一种基于无人机高分影像的水利工程管理范围划定流程与方法。对无人机高分影像进行分类和信息提取，结合 GPS 勘测及空间数据输入，按照提出的判别方法、划定流程进行水利工程管理保护范围的划定，可明确具体的划定范围值。将划定方法在北京市通州区水利工程管理保护范围划定工作中予以应用验证，验证结果表明：基于无人机高分影像的水利工程管理范围的划定方法不仅可用于小型水利工程管理保护范围的划定，也可为大中型水利工程的具体划定提供参考，对加强水利工程的实施与管理具有重要意义。

Abstract:

Aiming at the lack of current norms and standards to guide the delineation of management and protectionareas for small-scale water conservancy projects，as well as the absence of an established and applicable process，this paper proposes a method and process for delineating the management scope of water conservancy projectsbased on high-defi nition imagery from unmanned aerial vehicles（ UAVs）. By classifying and extracting informationfrom UAV high-definition imagery，combined with GPS surveying and spatial data input，the management andprotection area of water conservancy projects is delineated following the proposed discrimination method anddelineation process，thereby clarifying specifi c delineation values. The proposed delineation method is applied andverifi ed in the delineation work of the management and protection area of water conservancy projects in TongzhouDistrict，Beijing. Verification results show that the method based on UAV high-definition imagery for delineatingthe management area of water conservancy projects can not only be applied to small-scale water conservancyprojects but also provide references for the specific delineation of large and medium-sized water conservancyprojects，making it of signifi cant importance to enhance the implementation and management of water conservancyprojects.
