预控与协调:城市水系保护区的划定路径及管制措施

Prevention And Coordination: Path And Control Measures For Delineation Of Water Conservation Area

在完善水利工程的基础上,因地制宜、科学合理地划定重要水系的保护范围并制定相应的管控策略,对保障地区的生态安全格局具有重大意义。文章以淠史杭工程的重要分干渠—合肥市滁河干渠沿线水系为研究对象,阐述了城市水系保护区的划定方法与路径:采用数值模型计算法、经验法和GIS辅助法等多元方法,在科学预控的基础上,守住水系保护的底线,通过协调多方面利益群体的利益,"有保有压"地划定保护线,统筹考虑水系周边地形、坡度、汇水条件、重大项目及景观等要素对保护区范围的综合影响,确保生态优先、绿色发展的目标的实现,以期对今后同类型水系保护区的划定以及国家层面出台关于水系保护区划定方法与标准细则提供一定参考。

Water conservation area delineation is significant to regional ecological security. This paper takes Chuhe canal, a major sub-channel of Pishihang hydrology project, as a study case, discusses the method of urban water conservation area delineation. With numeric model calculation, empirical approach and GIS assistance, it makes scientific prediction, sets bottom line, coordinates multiple benefits, integrates geographical and other elements, secures ecology first and green development visions, and provides a reference for other cases.
