基于实测河网的河流编码算法

River Coding Algorithm Based on Surveyed River Network

摘要: 提出了直接对实测河网进行河流编码的思想，设计并实现了基于实测河网的编码算法．解决了实测河网编码过程中出现的双线河转换、河段流量确定、拓扑结构描述等难题，提高了河流编码的实用性．通过对长江等流域的编码测试，验证了本文所提出方法的有效性．

Abstract: An idea for coding the surveyed river directly is presented,and a river coding algorithm based on surveyed river is designed and implemented.Some difficult problems in river coding such as the double-line river transformation,river flow matching,and river network topology expressing are solved,so the practicability of river coding is improved.The algorithm presented in this paper is validated by coding the YangTze drainage area is test.
