南水北调中线工程沿线文物分布特征及其受渠道工程影响的模糊评价

水资源开发利用必须与文物保护紧密结合。南水北调中线工程的设计和建设中必须考虑其对沿线数量多、分布广的文物的影响评价 ,以便通过调查和评价来保护这些文物。工作中我们从对水系分布、地层岩性、地貌类型划分 ,文物级别、保护状况及同引水渠道空间关系等调查入手 ,一方面在输水渠道两侧各 3km宽的影响范围内 ,对不同时代的文物地貌分布特征进行了统计 ,另一方面 ,用影响指数E对沿线文物受影响的程度及保护等级进行了模糊定量评价。

GEOMORPHOLOGICAL DISTRIBUTION OF CULTURAL RELICS ALONG THE CANAL LINE OF THE MIDDLE ROUTE PROJECT OF WATER TRANSFERRING FROM SOUTH TO NORTH CHINA AND POTENTIAL INFLUENCE APPRAISAL

Development and utilization of water resources must be closely combined with the preservation of cultural relics. That' s the case found in the plan and design of Middle Route Project of Water Transferring from South to North China. In this work, we investigate the river system, lithologic characteristics of geomorphic , grades of cultural relics their preservation situation and the spatial relation to the delivering canal. On the basis of these investigations, a statistics of the distribution characteristics of different-time cultural relics within 3km wide zones on both sides of delivering canal with respect to landforms was carried out. On the other hand, by using influence index E, a fuzzy quantitative appraisal of the influence degree on the cultural relics and their preservation graded was completed. Thr result enabled us to have a systematical recognition of the statistical characteristics of the cultural relics distributed within the 6 km wide zone. Meanwhile, it has also important referential and instructive meaning in planning of concrete sections of the project, adjustment of canal line, as well as design of impevious works.
