水利遗产保护规划图图例设计研究

Legend design of planning map for water heritage protection

由于古代水利工程保护的特殊性,在保护规划图编绘过程中发现已有规划图编绘技术标准不能满足实际工作需求,突出表现在现有规划要素图例不能完整地表达保护规划内容。根据古代水利工程保护的特殊要求,结合当前已有的规划图编绘技术标准和成果,提出了京杭运河保护与管理规划图图例系统和具体设计方案。

Considering the special characteristic of ancient water conservancy protection works, it is found that existing technical standards for map drawing of protection plan cannot meet the actual needs and requirements, for instance the legends are unable to reflect the contents of the plan completely. In accordance with the spe- cial requirement in the protection of ancient water conservancy project, the current technical standards and achievements are studied and a legend system and specific legend design for the protection and management plan of Beijing-Hangzhou Grand Canal is put forward.
