长江南京段岸线水源地适宜性分析与评价

结合前人的研究成果、相关最新统计资料以及有关专家的意见综合衡量,通过实地调查和论证,基于水源地岸线适宜性分析的目的,选择确定了岸线稳定性、岸前水深、流速、岸线利用情况等4大判定因素,制定了岸线评价的基本程序和主要步骤。通过运用GIS、统计分析、综合分析等定量、定性方法,完成了研究区域4大因素的评价。基于简化的层次分析法(AHP法),对长江南京段岸线进行水源地适宜性评价,给出了初步的定量评价结果。

Evaluation on suitability of riverbank water source in Nanjing section of the Yangtze River

Combined the former research results, interrelated new statistical data and opinion of some experts together, via investigation and argumentation, based on the goal of suitability analysis of riverbank water-source, the paper chose four determinant facts that included stability, depth, current velocity and using status of water-front resources, and laid down the primary process and step of riverbank evaluation. The evaluation of the four determinant factors are completed by GIS tools, statistic methods and synthetic analysis. Based on the predigested AHP, it evaluated the suitability of riverbank water-source in Nanjing section of the Yangtze River and got primary results which has better combination with interrelated plan.
