| Zheng drainage is not only one of the oldest canals but also a monument of ancient water conservancy project in China. with a history of 2200 years, planty of historical sites of Warring States, Qin, Han, Tang, Song, Yuan, Ming and Qing dynasty,distributed into its headworks; Jinghe River Basin which located at the headworks still has an important ecological significance to the evolution of landscape structure, along which natural resources is abundant, making it to be the outstanding universal value- "the natural and cultural heritage."Landscape architecture, landscape ecology, urban planning study, heritage protection and other disciplines theory are adopted to build the theory and methods in research for the Canal Heritage Corridor,which is applied to the construction of the headworks of Zheng Heritage.It is possible to make contribution to the protection of canal heritage and the inscription of Zheng drainage.Firstly, the heritage structure, value composition and evaluation principles are clearly clarified based on the analysis the concept of canals.After that, the basic theoretical framework structure and construct canals Heritage Corridor are summarized. It is suggested that the research on the construction of Heritage Corridor can be determined by the suitability analysis, resource,ecological survey analysis and evaluation, themes, the protection and display, the overall plan and implement countermeasures.On the basis of these theoretical, headworks of Zheng drainage are studied in practice in the following.Through literature and field research, its irrigation canal includes headworks sites(8), oxbow sites(7) and the ruins of the old bridge(4); other intangible cultural heritage, including records of ancient water conservancy stone( 28) and stone writing(4); intangible cultural heritage of water technology(4), folklore(3), folklore(9), folk culture(8), archives and documents(13).Besides, elaborating the history, present situation and characteristics of heritage respectively, building the corresponding evaluation index system with AHP and quantifying evaluation of heritage resources, divided into three levels.Headworks segment of natural systems, including natural resources and natural landscape ecological corridor in two parts. Natural resources include mountain landscape(6), water(12), vegetation(5), rock(8), beaches(5). First of all natural resources, landscape characterization, and the establishment of evaluation index system and its quantitative evaluation is divided into three levels; principles and methods followed by the natural ecological corridor elements characterize and use them Landscape Ecology ecological assessment.By the investigation, characterization analysis and evaluation of the classification of the heritage and natural systems, Heritage Corridor for headworks of Zheng segment is built. First of all, the theme of "natural Water Conservancy Museum" is determined in the consideration, and goals and principles for the construction are also set; secondly, on the basis of the heritage distribution and ecological assessment,the scope of protection are divided as the core protection, main protection and perimeter protection,and the guidelines are formed relatively. In the same time,the conservation and presentation methods and measures of heritage resources are also determined on the basis of the natural landscape resources evaluation; Finally, build the overall pattern of Heritage Corridor, explore the implementation of countermeasures from the green corridor, recreation system, interpretation system and services facilities. |
